Thanks Steve, for these updates. I hope your back is healing up.

I plan on purchasing the Mystery Amp. I have returned my Primaluna Dialogue Five and PS Audio PWT/PWDII. I have freed up the funds to proceed with this Amp.

I own the SE84CS stock & SuperZen CKC.....never to be sold. I regret letting my Torii MKIII go. Point being, you don't make Amps that sound "just good enough". You sir, pain staking create instruments for the music to get out.

I look forward to its release. Cheers to all, and all have a safe and fun Labor Day Weekend.    -Stone of Tone

Too bad you didn't love the PS Audio Duo, sorry if I steered you wrong, I just adore mine.

Why the Mystery Amp Tone?  Why not a used Torii Mk III (I bet you'll see some on the market!) or a Mk IV?  I mean, you don't need the power of the Mystery Amp. I can't see myself needing the power of one until I buy a big ass house somewhere if I ever do in the future. And if that happened it would probably be the Mystery Amp Mk XXVI!

Lon, you did not stir me wrong. I have always appreciated your input. I am also very pleased with Music Direct not having a restocking fee. I also returned the Primaluna Amp as noted. I took a hit on that one...but I needed to reconfirm to myself how Decware is just plain superior.

I do need the Power. I sold my Torii MKIII because I wanted more Power in my Living Room Rig.....where the Mystery Amp will be.

"That actually started the night, and so far I've just been snuggling into the midrange in one of the most juicy amplifiers I've ever heard...   Think Mini Torii with 10 times the power and 80 times the weight...  it's just insane...  I really can't believe this design can sound this good...  it certainly didn't with my first choice of tubes and misc settings....

So, if I stopped tonight, it would be a success, I'm certain of it.  I'm just getting started".
I have heard the Mini-Torii in 2008 with Tube regulation....now add 10 time the Power and 80 times the weight.

The development of the Torii Mono's & the Mystery Amp, I believe has led to the significant development now found in the Torii MKIV***. Steve will need to confirm my speculation on this. That development being the no negative feedback circuit for more Transparency.....bring these push pull Amps with no Negative Feedback closer to the Transparency of the SE84CS which is benchmark for me...and will reign in my Listening Room until it is dethroned. The huge Caps on the Mystery Amp will take for ever to burn in....then I bring it in the Listening Room someday. But, it is for the Power to run my Polk SRS SDA 1.2 Speakers.

•In place of the adjustable bass dampening control I have created a re-constructive feedback circuit that improves clarity, detail, and definition at all frequencies.  It is on a switch so that you can use it or not use it.  (everyone will likely use it)   This mod replaces the bypass caps that were on the cathode of the input stage.  Those caps eliminated the naturally occurring local negative feedback in that tube.  Instead of a bypass cap, I use the output transformer in series with a couple networks that float the output stage above ground slightly.  The result is less phase angle distortion resulting in better transparency.  This was an accident, that turned into another discovery.  It's one of the cooler things that's happened in the past couple years and it will be fun to here peoples impressions of it as they get their MK III's updated.

Okay cool. I'm not at all tempted by the Mystery Amp or the Mk IV. I don't need more power, and I think the Mk III is more "flexible" than the Mk IV will be, and a well seasoned Mk III is just butter for me, just what I want. More transparency does not mean more musicality for me, I have more bad recordings than good to listen to and with the flexibility of the Mk IIIs I have I can make things listenable, and I listen.

I have a Vaughn-modified C amp in my Dad's system and while my original Mk III was back in Peoria for upgrading I had it in my main system. I really do see the super transparency and magic in those amps, but I can honestly say I missed my Mk III insanely and really prefer its mellow drive and ability to be made more forgiving. That I need most. It has gobs of weight too with the HR-1s or ERRs. I can't ask for more and won't.

But I'm excited for you! Keep us posted! (I know you will).

I hear you Lon. I am very interested in the HR 1 as well. I am going to Decfest! I will hear them till the wee hours of the morning before retreating to my Hotel Room.

I have these Polk SRS SDA 1.2 Speakers I have become so enamored with (outside the Listening Room) in my Living Room. They can be run with as little as 21 watts per channel in Triode and 42 in push pull as I witnessed from the Primaluna Dialogue Five I had briefly. Briefly, is correct....Upscale Audio only had a 14 day trial period on the Prima and a 10% restocking fee. I spent a lot of time with them....and the short trial period was just as lame as the Primaluna Amp was! But, I digress..... .

I know the Mystery Amp can Power them (Polk SRS SDA 1.2) first hand and by the late Julian Hirsch measurements of these fun Powerhouse Speakers.
I am also interested in running the new KT120 Tubes in it. I want this different animal in the Living Room vs. what I have in my Listening room.

PS-Beowulf, YES.....I am fortunate to have Audio Alchemy since 1995 and it takes a back seat to nothing when decoding the Redbook Stnd. Peter Madnick was paid to go away I think (he never has really gone away/just stopped making 2k Dac combo's that kick the sh_ _ out of other under 10k DACS)....he should design for McGowan IMHO. The PMD 100 & 200 Chips from Pacific Microsonics/Prof Johnson of Referecne Recordings....dual 20 bit Ladder DACS (one per channel)...analog output stage....Peter's design.....and the Volume Attenuator with adjustable voltage output....I rest my case.  Party on Wayne-Party on Garth.

If I hit the Powerball....I will call Peter Madnick on the phone and have his Constellation System(s) installed!  hehe

.... including Peter Madnick, Audio Alchemy's co-founder. Audio Alchemy's little back boxes, long discontinued (the brand sadly disappeared after it was acquired from the original partners) (uhmmm), are still highly coveted by studios and audiophiles around the world.

Telarc used the Pro 32 & 3.0 DAC in Studio...to name one.

Stone, from the way you talk about those Polks I gotta hear them sometime!  Just checking, but is this the setup you have with the Audio Alchemy stuff?  If so, not a bad price ...

Another Update:  In the final hours with only 29 days to the opening curtain (DECFEST 2013) I'm pleased to report things are going well despite a few attempts to upset the applecart by the powers that be.

One attempt was the accidental improvement I made in the TORII MK IV.  Obviously if the audio Gods were going to pick a time to enlighten, it would be an attempt to humble, so they made the MK IV almost twice as good just to test my resolve on the Mystery amp.  I still like it.  No, Love it.  The two will no doubt be compared over and over again but it will always be apples and oranges making the comparisons futile.

Another attempt was disguised as Father Murphy when the amp developed a hum that it never had before... and with only a month left till curtain time... go figure.  Turns out it was the audio Gods helping me do some final tweaking by using Father Murphy to steer me to the idea.  I had a ground at the input jacks which are supposed to be isolated. It developed with expansion and cooling of the chassis over time compromising the insulator. I couldn't figure out what happened for days. Last night I told my friend Dave that the amp could be fixed without adding any parts at his insistence that it would need another pie filter and more segregated supplies... even though I had no idea what the solution was I knew it wasn't what everything was pointing to.  Today I worked all day on tracing the eddy currents in the chassis chasing what I call inter-dimensional ground loops trying to make the hum stop.  I discovered that with this insulator compromised a ground loop had developed through the input cables and volume pot, but not until AFTER discovering a better way to ground it which corrected the problem in the first place... so now when UPS vibrates the thing to death in the back of their trucks and an input jack grounds itself at the chassis, the amplifier will still remain hum free and work perfectly.

This is how you know you're being guided by a higher power, because it is assumed these spirits transcend time and can therefor see into the future.  Saw one of these amps start humming and disappoint the hell out of a special customer which caused an unpleasant chain of events.  Decided to tell me about it.

Anyway, the fact that Father Murphy and the Audio Gods are active in these final weeks is good news, and gives me great confidence in what I'm hearing.

Speaking of that, I have been listening to my newest speakers with it and the sound quality and refinement is amazing.  They actually made my corner horns sound like sand paper in the top end... first time ever.  

So I will keep you posted as things continue, meanwhile I'm still listening to it, and tomorrow without the hum and stress of not knowing how to make it go away.

Nope, Beowulf....the thread post you put up is for the cheapy Alchemy stuff.

Steve, very cool how this shook down on solving the hum and a better way to ground it.....for the Mystery Amp!

I look forward to hearing it with the DM945's.  I can't wait till the Fest...I sold Medtronic stock...and I'm jonesin' for some Decware Products.   -Stone

10-Roger all that.  Just when I thought I was about to get the system settled for a bit... then along comes all this stuff.  There is no cure for audiophile nervosa.  And there is only one semi-effective treatment: constant infusion of new & improved !!!

Not to much audiophile nervousa for me. If the piece does not cut it after appropriate set up and burn in...it gets returned or sold...like some of my recent endeavors. I just know what I like when I hear it....then buy/enjoy and keep it.    3 weeks & 4 days until the FEST!

I have had my AA Front End for 18.5 years and counting.
I have had my SE84CS for 12 yrs & 3 months.
I have had my SuperZen CKC for 10 months....never to be sold.
I have had my Kimber Select 1030 IC & 3033 Speaker cable for 13.5 yrs.
I have had my Parker Crusader's for 8 years.
I have had my Polk LS90 for 20 yrs & 6 months.
My Vintage Polk SDA 1's for 2 years next month.
(*these musical SDA 1's stay in the Listening RM with LS90 switch outs...my behemoth SRS SDA 1.2 Speakers are out in the Living Room*)

I am in my 3rd house with my best Acoustically Treated Room yet!
