I tried many silver cables, like Nordost cables 10 years ago. I did not like silver cables even though it provides very high details and resolution. But the sound is thin and image size is small. I like pure copper cables because of its warm sound. I feel that it is more close to vinyl sound.

However when I listen to Duelund hook up wire version2, I love its sound. It provides neutral sound with both excellent ends. It gives very high resolution, details in both high and low, fast transients and long note decay, good airy and excellent trimbre. impact bass, slam and bass textures and excellent dynamics.

I make one 5 feet IC from Duelund hook up wire version2 (4 cables per channel) and WBT 0110 Ag RCA Male plugs. I love this cable. It beats my MIT Avalon IC by substantial margin in term of details and dynamics.

This IC does not have RF shield braid, same concept of AntiCables, which provides open sound with excellent transparency. It is completely silent when I use my ear close to speaker. It confirms no RFI problem.

The weakness of IC is that the 4 wires of Duelund hook up wire have to rearrange to separate each wire not to close or contact each other. The more space between them, the more transparency.

DIY cone spikes under ZMA.

In evaluate listening section of each mod stage, I did not use Sub-woofer. Because it is time consuming to adjust sub-woofer to seamless integration with main speakers. Now I finish my mod ZMA and doing more burn-in of mod parts installed in ZMA. It transforms ZMA to be much more sublime now.

But by adding sub-woofer Martin Logan Depth to my main speakers Avalon Avatar (Frequency response from 45 Hz to 20 MHz), my system improves to next level top notch. It is quite close to my friend system of Wilson Audio Alexia speakers and VTL Siegfried Series I Reference Monoblock Amp. My friend system is super top notch in both end top and bottom frequency extension and macro and micro dynamics. I think that this is current trend sound quality of new super expensive Hi Fi system. However by adding sub-woofer, my system is close to him now. But my system has better refine and delicate sound quality to him. I am very satisfied.

More tips of sub-woofer set up.
1) Please use interconnect cable quality as same as your main interconnect cable of your main amp. In the past, I tried to save money in sub-woofer interconnect cable. The result was poor integration of sub-woofer to main speakers. I blamed poor sub-woofer and though that sub-woofer sound quality concept did not work as same as full frequency floor standing speaker.  But when I change sub-woofer interconnect cable to synergistic research IC which is quite expensive. Now sub-woofer can integrate to my main speaker seamlessly and produce top notch sound. And it is flexible to tune bass to suite your listening room.
2) I just place small remaining piece of Soundcoat damping materials under sub-woofer spikes. It transforms bass to be very tight, perfect control and details. it is a surprise. Now Soundcoat damping materials is my magic for doing vibration isolation in my system with very low cost.
3) Make sure that your sub-woofer is fast enough to match your main speakers. It is about time alignment. The sound wave from your sub-woofer should arrive at the same time as the sound wave from main speaker. In the past many sub-woofer are fail in speed to match with main speaker so that they can do poor integrating with main speakers for superb musicality sound. But nowadays sub-woofer improve a lot and many owners of Avalon Isis are using sub-woofer to integrated with Avalon Isis successfully.

Hi South - i run old Wilson X1/Grand Slamms. I run a Velodyne DD18 in parallel, from 41hz down (using a 48db rolloff above 41hz.) The Velodyne set directly on the floor used to be at volume 8 (quite low)...and then upon placing it on an Auralex isolation platform, i ended up finetuning the volume to 32 after the distortion from vibrating the floor was largely taken care of...and thus, i could drive much purer, clean bass to even better integrate with the Wilsons.

Some Avalon owners use subwoofers as an option to complement the last octave down



4) The Martin Logan Depth sub-woofer has phase selector of 0, 90, 180 and 270 degree and volume attenuating of freq 25 Hz which is very essential to dial your sub-woofer to be seamless integrated with your main speakers and solve low freq problem from room reflection. My cut off LFP is 30 Hz. It can be selected from 30, 35, 45, 55, 65 and 80 Hz.  

My next trial will be downloading Dirac Live for 15 days trial period of Digital Room Correction program.

I just posted my impression in audiogon forum of
 Lightspeed Attenuator - Best Preamp Ever?
as below;


11-21-14: Vyokyong
Hi,

I am using Lightspeed Attenuator for 3 weeks already and want to share my impression here.

My system are;

Audio Note DAC 3.1 custom modded TC Reference MBX. by Bill Baker, Response Audio.with two separate mono power supply unit as same as preamp L2, Mac Mini, Offramp 5 USB convertor, DIY Duelund wire RCA IC, XLO Purple Rush power cord
Zen Mystery Amp. MIT Oracle RCA IC. Synergistic Research Tesla Reference power cable.
Avalon Avatar speakers. MIT Oracle speaker cable.
Hydra 8. ZSB. Kubala Sosna Emotion PC.

I have modded my Decware Zen Mystery amp by removing volume pot out of signal path. It improves much substantial transparency and dynamics to my system. I don't use any preamp. The source Audio Note DAC is connected directly to Zen Mystery amp. So that I need to have volume control for my amp. I read a lot forum about active premap, passive preamp and all types of volume control from volume pot, shunt resistor volume pot, Auto Transformer volume control (ATVC) and Lightspeed attenuator. My decision to go with Lightspeed attenuator.

I love my system to have amp connected directly to source, no preamp. The sound is fabulous. I temporarily use digital volume control in Pure Music software while Lightspeed attenuator was not arrived yet. The digital volume control is acceptable but still creates some sound distortion that you can hear.

When Lightspeed attenuator arrives, I connect it between my amp and source as a preamp. I hardly hear any different between having lightspeed attenuator in my system and without it in my system. It is so transparency. I give 99.5% transparency to directly connecting between amp and source. The 0.5% transparency short is for need of extra one interconnect cable which affects on sound quality. I am very happy and highly recommend to use Lightspeed attenuator as your preamp if you love your amp directly connecting with your source. Or your source has a very excellent sound and you don't want preamp to change its sound quality. And your system don't have any impedance mismatch with Lighspeed attenuator.

For active preamp, therea re some benefits because there are two more functions in active preamp which passive preamp does not have;
1) Gain stage function. Its function is to increase voltage of signal to improve loud and dynamics of system.
2) Buffer stage, its function is to prevent impedance system mismatch. If your source sound is harsh, buffer stage may help to reduce harsh sound.
Then active preamp is benefit for some hifi system.

You select the best for your system.

Hi,

I just tweak ZMA by using acrylic box to cover tubes on top of ZMA as in the picture. Its function is to prevent micro-vibration from sound wave attacking on tubes. It is the same function as Herbie tube damping. But acrylic box is prevention device while Herbie tube damping is passive device. I have one pair of Ultrasonic RX tube damping from Herbie. It is effective to make sound more focus and clearer. But its side effect is that it can make sound controlled too much and feel stress. The acrylic box make sound more focus and clearer without sound stress or be controlled too much.

One weakness is that when you want to turn volume or turn on, turn off the amp, you need to lift up the acrylic box.

However I highly recommend to go with Acrylic box rather than Herbie's tube damping for save more money and better damping function.  

I was going to say the same thing as Donnie - I'm betting that big panel on top resonates at an audible frequency, which is then dumped into the chassis where the acrylic box rests on the ZMA.

I'd also much rather not trap all that heat in there. Those small holes don't make me feel like it's well ventilated, especially when I don't see any place for the cool air to be drawn in (preferably from below).

I just don't see this as a good idea.

That's a great point Donnie. Though loud sweaty bands in bars are definitely NOT my thing, no stereo really replaces live music. Not even when you're just alone in your living room creating it yourself. But. . . Decware components and their few compadres tempt you to inch closer and closer. . . .

I personally find that leaving the amp open and Herbie's tube dampers and using Mapleshade footers as chassis weights work best for my setup (which includes Herbie's Iso-Cups and PS Audio PowerBase). We all have different tastes and different likes, and also things work differently in concert with other isolation and cabling components, etc.

Hi,

Thanks for all commend. The real problem is caused the reflective sound at big panel of acrylic box which is placed between my front speakers. It ruins sound stage a lot. Even though I feel instrument's image is more focus. But the whole sound stage is flatter, less wide and congest, just between the speakers. The previous sound stage is very depth and wider than both speakers.  I accept mistake and remove the box out.

Thanks again for commend.

vyokyong,
Your comment brings up an interesting thought.
Why do we put our equipment between the speakers? Is there some unwritten law about it?
Would it sound better if we placed all of these boxes somewhere else?
My amp sits behind my left speaker just because there is a wall outlet  close to it. The bad thing is that I have a 20" computer screen  setting more or less between  my speakers.
Maybe it is time for me to reconsider things around here.

Hi;
After reading Jim Smith's book "Get Better Sound" my equipment was removed from between my speakers and placed on the right wall of the listening area. Since the rearrangement I have noticed an all  round increase in sound quality as follows;-
(a) Increased sound-stage width and depth.
(b) better 3D imaging and clarity of notes
(c) performers and instruments are more focused.
(d) Increase and clarity in bass response. The sound from the four 15"
    mid bass drivers at the rear of the Zu Definitions is now bouncing  
    off the front wall into an open area and not into a rack full of
    equipment.
The only downside with this setup is that experimenting with various speaker cables is costly. However, having installed a twenty two feet length Clear Day Shotgun silver cables  my speaker cable search ended.

Enjoy the music
   

The bass is dull when power cord plug made with metal is wrapped with ERS sheet.

I recently saw a picture where a guy had put copper pipe sleeves over his power cord connector at his amp.  I don't know the theory but is this what the ERS sheet is for?  Some kind of Faraday shielding?

I'm looking at getting some power cords that have twisted main conductors and EMI/RFI shielding in the sheath.  I notice that some cords are not shielded.  I wonder if covering the connector brings the shielding right up to the amp?

Thanks for the explanation.  That makes sense.  I've been shopping for power cords and I was under the impression that shielding is important and a good thing.  Interestingly, The Decware power cords are not shielded.

If a copper pipe or other shield is used over the connector, does it have to be connected to the ground or anything to work?  Or is it completely passive?

I just ordered the Decware power cord.  I asked Steve about shielding and he sent this reply.  Seems to bear out
what Vyokyong quoted from Empiracal Audio above.

"As for cords, they emit no RF so the only thing to worry about is 60 cycle field which is mostly canceled by the braid.  When we were testing cords during the design process for the DHC-1, we found it to sound better than shielded cords.  Don't know why, just went it."

I agree, Bias is important. I think I might want to look more into where my sweet spot is. I've just been setting it at 50ma and forgetting about it, but maybe I should be paying more attention to the levels.

Hi Stone of Tone,

Nice to hear from you. I am very happy with my hifi system now.
I had not changed any thing in my hifi system for 8 years. I was quite happy with them. However my journey started when I read Decware forum about Decware tube gears.

First gear I changed is ZMA to replace Pass Labs X150. I wanted to try tube amp and I worried that ZMA cannot drive my Avalon Avatar speakers which has sensitivity only 85 dB. I wrote e-mail to Steve. He said that ZMA should not have any problem to drive Avalon Avatar speakers. However he insists that if I have chance to change speakers, he would recommend one full range driver speakers with high sensitivity > 90 dB. I told him that I love my Avalon speakers and did not want to change to other brand speakers . ZMA is a masterpiece amp. It turns my hifi system to next 2 -3 steps up to new league level.

Then I wanted to play music computer server instead of CD player. I have Accuphase CD/SACD player which can be accepted SP/DIF signal from computer. I heard that music comp server beat the best transport with much lower cost than expensive transport. And it is true.  I use Offramp 5 USB-SP/DIF converter, Mac Mini, Pure Music software and Mojo Audio LPSU for both Mac mini and Offramp 5 and feed signal to Accuphase DP77. The result is that I get much better sound quality than playing by Accuphase CD player or even SACD player.

However I wanted to upgrade DAC again.  I did research a lot of DAC and there are two main groups of DAC. First DAC group is Sigma Delta DAC chip which is main stream DAC products in market. The second group is minority in market, it is R2R DAC chip or multibit DAC chip. I choose to go with R2R DAC chip because I think that R2R DAC chip is like no-negative feed back amp design concept. It provides raw and keep original record signal. While sigma delta chip is like negative feed back amp concept. Then I read about Audio Note DAC of Non Over Sampling rate (NOS)  against high over sampling rate. I believe in NOS concept then I bough Audio Note DAC 3.1 modified to be DAC 4.1 level to replace my Accuphase DP77. It is a big step jump of my hifi system again. I read and follow your PS Audio Direct stream DAC and Yggdrasil DAC which use R2R DAC chip also. I confirm that you go on the right track of R2R DAC chip, not Sigma Delta DAC chip.

Third, I read about modified amp with boutique components or DIY. Then I went to route of mod ZMA. And this is one big 2-3 steps up to next level of my hifi system again. It is really huge improvement. I would like to suggest to give important to upgrade signal path by pure silver connection and wire in signal path. And I very, very, very  highly recommend to by pass your volume or gain control of ZMA. If the volume control is by pass or no volume control, your hifi system will gain huge transparency, micro dynamics and macro dynamics. It likes you take out blanket out of your hifi system. Now I use Light Speed Attenuator to control volume or gain instead. It is most transparency and cost you few fortune of less than USD 500. I ordered two mono volume control left and right so that it helps to balance your left and right sound level easily.

I think that my system is going to near peak level. But I am not sure that it is only my illusion. So that I visit many hi-end hifi dealers to listen to their expensive gears. But none of them make me impression compared to my current hifi system. I feel more confident in my system and big thank to ZMA. Even though my speakers is Avalon Avatar and now used price is only USD 1,800.

Even in my sub-optimal room, they truly disappear. It never sounds like the music is coming from a box; they have a very stable image that tends to be more deep than wide (in my room). It's easy to identify where each artist / instrument is and I think this contributes to a "live" sound. Others have commented on this characteristic, and it certainly bears out for me. It is as if you are transported to the original venue, recording studio or stage rather than having the venue brought to your room. I'm not sure if that makes sense without hearing them, but you'll understand if / when you audition.

The only drawback I hear in my system is they don't have the impact I have heard from some big-time systems on snare drums, etc. I once heard Take Five via a Walker TT and all burmester gear including their big speakers and I'll never forget the impact it reproduced on the drum solo. My system can't do that but it likely has as much to do with the other gear. I guess it's unfair to compare my $25k rig with a $100k + setup...haha.

Now there are two weakness of my system which I need to address.
1) If music file with low gain record is played, it is not loud enough. I need more gain so that I will add preamp to my hifi system. However I love passive preamp more than active preamp. Now I am looking at Coincident Statement Line Stage preamp (The synthesis of the best passive preamps with all the advantages inherent in an active line stage). There is no any resister and resister stepped attenuator volume control in signal path.

The Coincident Statement Line Stage is the most direct, purest approach in active pre amplification. The input signal travels from the transformer based mono volume pots to the transformer input and then to the 101D tubes for gain and lastly out through the output transformer. The 101D tubes are directly heated triodes that are the most linear amplifying devices ever invented.

2) My lovely small 2 ways Avalon Avatar speakers with martin Logan Depth sub-woofer.  I went to listen to Avalon Transcendent. It is not much improvement compared to my Avalon Avatar. Even I listen to Avalon Indra which is much much better than Avalon Transcendent. I am still happy with my Avalon Avatar and save my money. It is a magic of Avalon Avatar that it can still compete with Avalon Indra model. But I give big credit to mod ZMA that push Avalon Avatar performance to near Avalon Indra with Krell Amp or Boulder Amp.

Last week I went to listen to Avalon Eidolon Diamond speakers. OMG, it is very excellent and make my Avalon Avatar out of league. And I am lucky that dealer have special price clearance sale of Avalon Eidolon Diamond. Because it is discontinued models and will be replace by Avalon Compass Diamond model. This Avalon Eidolon Diamond is my dream speakers, I had never though that I can afford to buy them. But now it has 40% discount from MRSP. I made a deposit booking and be waiting to get them end of this month.

I think that I will be only one person in the world that have ZMA to drive with Avalon Eidolon Diamond Speakers. I will report back when I get them and set up the system well. I hope that I will get the impact sound that I heard from big dollar system.  
   

Hi,

I just want to update that I have changed my main speakers to be Avalon Eidolon Diamond replacing Avalon Avatar. Now the Martin Logan Depth sub-woofer is not used any more. There is enough bass and it is very high quality bass with pitch, texture, clean and control bass, no any bloated bass. What you get more than Avalon Avatar is that music has much more weight and body. Now I already understand that you cannot expect to get well body weight and impact sound if your speakers don't have more than 10" woofers. The book shelf speakers or floor standing speakers with lowest frequency to 35 - 45 Hz spec used with sub-woofer cannot provide real body weight and impact, it is just imitate in my experience of Avalon Avatar with Martin Logan Depth sub-woofer.

The Avalon Eidolon Diamond is one of the most sound coherent speakers. It is seamless integration from top to bottom frequency. First listening, you feel no dominant in any frequency of high, mid and low. But overall presentation is that it is so real LIVE music.      

It is like music band is playing LIVE in your room, you listen to music band, not HIFI sound reproduction system. The dynamics is effortless, no any compression or stress sound. The music can play loud with very clear note from each instruments, no blur, no congest at all. There is palpable singer and superb holographic image of all instruments. It is champion in 3D holographic sound imaging. The speaker boxes are disappeared.
Live, unamplified music has unmistakable presence and clarity. Yet, at the same time it also sounds relaxed and no fatigue at all. The very breath of music flows as dynamic nuances and minute details are reproduced with the gentle touch of a master's brush. Thunderous low frequencies are delivered with authoritative and articulate control as you are transported into an environment of music that is effortless, natural, alive and whole.
Every music notes and singer words have their own bouncing sprung with energy, they are dancing together! I love this sound characteristic.

When I compare Avalon Eidolon Diamond with 2150 monoblock Boulder AMP and Esoteric DAC in dealer showroom with my Audio Note DAC mod to 4.1 level and ZMA. I feel that it is not so different while dealers system is much higher price than my system. The sound dynamics may be less than dealer system but my system is more liquid and organic sound with more nuance and textures. I must give credit to ZMA. It is a great AMP. (However the dealer set up may be not in good set up and Avalon speakers are very sensitive of toe in degree and speakers location placing in room to get best sound out of them).
   
The Avalon Eidolon Diamond is very accurate and neutral speakers. It will show any fault in previous system chain, if there is. And it is very sensitive of speakers location placing in room and toe in set up of speakers. If anything wrong, its excellent sound will be collapsed and becomes just ordinary sound speakers. If toe in is not enough, no focus image and no soul sound or you will feel not involve in music, lifeless music. If toe in angle is too much, the bass sound dull. But if you set up correct, its sound will be superb excellent sound which you cannot imagine that it reaches to this excellent level. My Avalon Eidolon Diamond has just been playing for 200 hours and its burn in is 400 hours to get full open blossom. It can be better.

I am very happy

Hi,

I want to add more about loudness level I get from ZMA.

For well high gain record music album.

The max SPL is 95 dB measured at 230 cm from speakers when ZMA is connected with Avalon Avatar (84 dB sensitivity and 6 Ohm load, minimum 4 Ohm)

The max SPL is 99 dB  measured at 230 cm from speakers when ZMA is connected with Avalon Eidolon Diamond (87 dB sensitivity and 4 Ohm load, minimum 3.5 Ohm).

ZMA can dirive Avalon Eidolon Diamond without any power constrain, no stress. Bass is very articulate and well controlled.

However some low gain music record album, the maximum SPL is only 84 dB SPL while I normally listen at 87-92 dB SPL. Then I plan to switch my passive preamp (Light Speed Attenuator pre-amp) to be active pre-amp (Coincident Line Statement pre-amp) in order to get more gain of 13 dB variable volume control. Or I will use both pre-amps together by LSA acts as volume control of ZMA and Coincident Line Statement acts as pre-amp. So that I can play both volume control to fine tune to get optimal dynamic body and weight level.

HOW CAN A PREAMP MAKE THINGS BETTER?

A good preamp becomes an extension of the source enhancing it's dynamics and overall voltage swing as well as enhancing it's output impedance to more effortlessly drive difficult power amps.  A good preamp can extract detail and timbre that is otherwise hidden by these conditions.  A good preamp can add body and weight and size to a stereo image and improve the depth and palpability of the sound stage. A good preamp can make tiny speakers and or tiny amplifiers sound and perform as though they were bigger then they really are.  A good preamp can organize the presence in a recording to create several more layers to the music.  It can pull things apart and make recordings sound less like recordings and more like real music.  FROM PRE AMPLIFIERS - do they help or hurt the sound?

I will report back when I get Coincident Line Statement pre-amp. It is variable transformer volume control (TVC) with active gain by D101 DHT tubed circuit pre-amp.

Hi,

I would like to report of adding Coincident Statement Line stage preamp (CSL) to replace Light Attenuator passive preamp (LSA).

Pro:
1) Excellent Authority and Dynamics. It is like you change car from 1,600 cc to 3,000 cc turbo charge. Absolutely dynamics and in different world to LSA. It means that ZMA + CSL provides dynamic authority as same level or better than SS amp. It makes you feel excite and PRaT. It can play loud as 101 dB of any album record (high or low gain).

Con:
1) All nuances and micro details gone or disappear or high definition sound is gone. LSA or dierct connect between source and ZMA provides or keep all nuances and micro details (high definition sound) which makes you feel realism of LIVE music band playing in your room, very emotional music.

Now it is dilemma for me to choose between Excellent Authority Dynamics or Nuance and high definition sound.

Power Supply Unit of CSL.

Hello Beowulf,

My pre-amp project started one year ago before new Decware Preamp news. If I know that Decware will launch new Preamp with XLR in put and out put. I will be waiting for new Decware preamp. Because I love Decware ZMA and I trust Steve. I did not buy CSP3 preamp as I read mix results working with ZMA. Or I think that CSP3 preamp is not good enough for ZMA.

As I read a lot forum about pre-amp. My interest go to passive pre-amp. Then I bought Lightspeed Attenuator passive pre-amp to try first. It provides best transparency pre-amp which is totally better than any active pre-amp. You hear transparency in different world from active pre-amp. It likes direct connecting between source DAC with ZMA.  However its weakness is authority bass and dynamics, if your source DAC cannot provide enough drive or voltage to feed ZMA. Even ZMA in put needs only 2 volts and my Audio Note DAC3.1 provides 2 volts out put. In general it is okay but there are some low gain record album that it cannot be played loud enough. (may be 20% of all my collections). Then I have to try active pre-amp or get pre-amp with 13 dB gain.

I choose CSLS pre-amp because of its concept to use Transformer Volume control instead of general stepped (resistors) attenuator volume control and provide 13 dB gain by 101D DHT tube circuit.  The main lost in transparency of active preamp is caused by stepped attenuator volume control which is resistors in signal path. So that if TVC is used then there is no any single resistor in signal path.

The CSP3 is good enough to use with the ZMA. I would not use it, if it could not provide the transparent musical fidelity I require. The problem with your CS Lines Stage is....it's getting in the way of your music, with to much RUBE GOLDBERG in its Topology. Tough truth on that....for you... . But, don't feel bad, so many so called high-end Preamps can't get out of the way like the CSP3 can....when properly administered.

Using the proper voltage output from the CSP3 makes it ideal. Plus, the Input Tube I'm using matters too. Those using shitty cables and not knowing what their doing with the CSP3 will report on what they deserve=poor results.

I have my KS6063's in!
Talk about even further involvement in my Music! Without getting into all the superlative adjectives.....they are an incredible addition and immediately apparent. The even further clarity and decay with further differentiation of instrumentation, is Whoa!!!!!!!!!!!!!!! You just want to keep turning the System up and up! It continues to maintain tonal balance at higher SPL's and weight ~ like a properly done Live Performance WITH ALL THE JE NE SAIS QUOI of detail/clarity/decay aforementioned! Truly incredible. Especially, when you consider my System already and some serious underhung clarity from the Driver's in the Adagio's.
The fact that I got these for 52% off with the premium WBT-0681-Ag Spades...makes this deal so much Sweeter!

Stone, has left the building!!!

Cheers, and happy Oktoberfest to all!
