"When I added the final component to the speakers (which I'll point out later after photos of the finished speakers surface in this thread), it only took 3 hours to initiate a patent application and it's the first time I've ever done that... but I've heard most of the Omni's at the audio shows, and am well aware of what has been done."

"So to take it all in, we have a speaker that could take a ZMA turned all the way up on disco music without distortion and completely "wreck the room", but yet is efficient enough to enjoy indefinitely with something as simple as the SE84UFO 2 watt amplifier."

......PLUS, the fine tuning/addition to your room treatment you mention.

YOU HAVE MY FULL ATTENTION.

I wondered the same thing. †I have the HR1s but my room is far from "ideal." †Didn't Steve say that the Eggs need a carefully treated and symmetrical room to bloom?

The eggs are currently prototypes. †The first production unit could be as far as a year away assuming we choose to put it in production. †Room compatibility, cost to make, and how well people like them will all be determining factors, so a little soon to starting putting yourselves on the list ; )

Steve, I LOVE that post about communing with the Gods to get the last piece of the puzzle on the Egg speaker!  Great stuff.

The Egg's and the 6C33C's, will be fun to follow the next 6 months to a year (and if you decide it's feasible, to bring to market the Egg's).

I have split this thread into two topics, this one, and then one specifically for the 25th Anniversary Zen Triode amplifier.  Once I announced it in this thread, the entire thing has been about the new amp so I gave it it's own thread.

http://www.decware.com/cgi-bin/yabb22/YaBB.pl?num=1510887200

I'll continue on with this thread as more developments come down the pike.

Yes, these will be called the DNA2.†As soon as I get the first production pair in the listening room, we'll shoot pics and get them on the site. Price not to exceed 4K for the pair.

I have every intension on producing a turn key pair of DNA2's for $4K or less. †Hopefully have the first production pair late this Spring at which point I can put them on the site and start taking orders. There is a serious synergy with these speakers and the 2 watt Zen Triode amplifiers. It's ironic because the DNA2 has a pressure centric bass response which is to say the louder you play the speaker, the deeper and louder the low bass gets. †This creates a real sense of excitement. The 2 watt amp gets the speaker just to the leading edge of this effect which makes the effect a very satisfying tease if there is such a thing.

Regarding plans, we literally just scaled up the DNA horn to fit an 8 inch driver. The only modification was to increase the length of the port from the thickness of the panel, to a length of 2 inches. The end result was a cabinet 16D x 9W x 38H - approximately. †We sell the plans for the original DNA horn with the 5 inch driver.

If you're familiar with the bass performance of the DNA cabinet with a 5 inch driver you can only imagine what happens when double the size! On something like a TORII JR or larger, the speakers performance gets unreal. Sadly you'll never know they could crack the kitchen ceiling if you only hear them with the two watt amps, but ironically these speakers make the two watt amp sound better than anything else we've tried so far. †HDT, ZOB, NFX, DM947, DM945, BETSY all coming in a close second. †

The combination of the Zen Triode Amplifiers on the DNA2's is exactly enough when turned up to max without clipping that you would think you listening to a Zen Mystery Amp (ZMA) witch is 40 watts! †It just communicates that sense of weight and control of the big amps, and since that is actually the true sound of a Zen Triode it pleases me to finally have a speaker other than my corner horns that demonstrates what the amp can actually do.

There is no substitute for efficiency with extremely healthy bass response and a tight wet midrange. No subwoofer, the entire crossover is a single high quality poly film capacitor.  The imaging is just sick.

The CSP3 Anniversary Mod.

Driven by the insane sound from the new soon-to-be released SE84UFO25 (25th Anniversary Zen Triode Amplifier), we were able to duplicate the technology behind the SE84UFO25 in our most popular preamp, the CSP3.

The technology is two fold. †First, the entire high voltage supply that feeds all the tubs must come from the cathode of the voltage regulator tube, which is as close to a high voltage battery as you can get, but with the advantage of better constancy. †Second, the entire power supply filter design has to be updated and then bypassed with the same beeswax caps used for coupling.

Since the CSP3 is made up of six triodes, three per channel, the high voltage node that previously fed all six triodes was split into two nodes by installing the SG5B tubes plates together at the node and then sending the filtered high voltage to each channel from the respective cathodes of each regulator tube. Once there, we collect the clean power and store it in a cap that matches the speed and size of the coupling cap. †In this case that's a .47uf which proved to be ideal as a coupling cap to ensure the proper bandwidth, but too slow for a power supply bypass in an anniversary series, so the .47 beeswax bypass caps were themselves bypassed with .022 beeswax caps, each channel separately.

On the other side of the regulator tubes, the main supply caps must also be bypassed to be fast enough to supply the other bypass caps through the VR tube.

Also the headphone output caps had to be bypassed in order to let you hear everything in front of them so that when you use headphones you get a similar sound to the line outputs.

I have paired this with the SE84UFO25 which is like an electron microscope on the signal path, and it not only passed, but made the damn thing sound enough better that I now can't live without it.



Can you find the tubes in this beeswax forrest?

Parts and labor on this mod is 570.00. †It is of course assuming your CSP3 already has the Beeswax caps option. †If not, you will need four more .47 beeswax caps which adds another 350.00 to job. We also change the input tube from a 6N1P to a 6N5P although you can still run any of the compatible input tubes you have in the past.

The specs of the unit remain the same with 30 volts max output, and 0.7% distortion at full output.

Fun stuff! †Ear Candy that ruins you.

Steve

Just took delivery of my CSP in January. I only use headphones. Would this
mod be worthwhile for me?

The big question is can I be without it while it's upgraded? Nuts!

If you only listen in headphones then the mod is probably even more beneficial since headphones themselves are magnifying glasses on the music.

Yes, Borris has an ear and records like I wish everyone would. †His stuff sounds gigantic, and rich and dense to the point of outdoing everyone else so you would think the recordings would be highly compressed. †They are not. †In fact he leaves about 6dB on average so he too has mastered density and in his world density multiples gain.

Happy listening!

I should think so yes.  The internal layout is a little different so I'm not sure what if anything I will run into in the way of extra costs.

Dammit Steve! †Just when I thought it was safe to lurk about the forums again you come up with a 25th Anniversary modification for the CSP3. DAMMIT!

Well, I am boxing up my CSP3+ (w/ beeswax caps) today and plan to ship it tomorrow after talking with Sarah about the details. And just when I thought my wallet was safe, at least for a little while... thankfully this mod is within my budget.

Time to put my old trusty Eastern Electric preamp back into temporary service until the MASTER has his way with my CSP3. Just DAMMIT... † Grin

It's better to be lucky than smart!  I didn't understand everything Steve told me about the mod but he did say that it makes the CSP3 super fast -- which is an advantage for analogue.  In general, if Steve likes and recommends something, I don't ask too many questions.

Several people have been asking about the DNA2 speakers that I've been using since October. †We are going to be manufacturing them, one pair at a time, and they look identical to the the smaller DNA horn. †These are an exactly scaled up version for an 8 inch driver. †After some testing the cabinet design offers tons of possibilities, but we chose the driver compliment used in our DM946/947 model. †The results have been dumfounding because the drivers sound nothing like they have in any other cabinet. †

Anyway, since tonight is my last night with a favorite amplifier, I thought I would demo the DNA2 horns with it on video so everyone can get a sense of what I'm hearing from these speakers...

Here is a link to the 13 minute video of the DNA2 horn speakers...

Very nice Steve.  Hopefully I will get an invite to listen to the OTL again once it has reached the new owner.  I remember hearing it two years ago at the fest and it was indeed special.  DNA2s sound pretty sweet as well.  I have those Boris tracks so I can get a pretty good idea of how they sound in person.

Having built the DNA with the original tang band and knowing (and liking) the driver compliment of the DNA2's, I may build some.  I have to dig around to find the DNA plans and can scale them up.

One question though, how do you increase the length of the port to 2"?  Are you using an actual port tube or increasing the thickness of the top chamber panel (and reducing the size of the chamber)?

I got my CSP3 with the Anniversary modification (CSP3A ?) back a couple days ago and I've been listening with the idea of reporting on the modification. †Unfortunately, Steve didn't pick the best guinea pig for his first CSP3 mod in that I don't do well with articulating what I hear.

I had the CSP3 out of my chain for a couple weeks or more and I was getting most of what I thought the CSP3 offered with just my ZROCK2. †It turns out that either I was mistaken or the CSP3A+ is in fact a big improvement. †As expected, I have to dial back the ZROCK considerably with the CSP3A back in (I have it before the ZROCK2) as I did with the CSP3. †What I seem to be hearing though is a more complex soundstage, such as I have in my environment. †I also seem to have an increase in detail. †As always, female vocals are especially sweet. †There may be a lot more going on but without the original CSP3 and the CSP3A+ side by side, I can't remember well enough to discuss it.

One coincidental (?) event was that after about 20 minutes with the CSP3A, I had a strong hum in my left channel. †I was eventually able to track it down to a bad 6N5P in the front position. †That was the same tube I had been running pre-modification so whether it failed at this particular time or if it had a fault that the CSP3A uncovered, I don't know. †One other artifact of the modification is that now I get popping on warm up and cooldown from my speakers. †It sounds like OA3 popping I sometimes get from my ZP3 or ZMA. †I'm assuming it's from the two hardwired OC2s Steve uses in the modification.

Anyway, I'm glad Steve did the modification and I think it was money well spent, especially considering he had the CSP3 for service anyway.

Interesting Archie! Keep us posted as you play around with this. I'm using a CSP3 with the Jupiter caps in my second system right now to both feed a Torii Mk III and for heapdhones. . . . I don't plan on sending it back for mods but you never know. . . Wink

Lon, my guess is that I am getting a taste of what your mono blocks are giving you.  

I would suspect that the CSP3 modification effectiveness might play in with the system synergy but with the ZMA, I find things better with the CSP3 (and/or CSP3A) in front than without.

I'm sure you're getting similar sound changes with the modded CSP3. I had a love/hate affair with the CSP2+ in use with the Torii Mk III . . . I felt that the ZBIT did more for my source than the CSP2+ and that the ZBIT and the CSP2+ was a bit too much. But the ZTPRE is different, I love what it brings even though I'm hard-pressed to describe what that is. . . It improves things but doesn't call attention to itself. (And with my two other sources besides the DSD DAC it significantly provides sonic improvement). I can imagine the mods both helping and also taking away the invisible nature of the ZTPRE I like so much. Luckily Steve hasn't mentioned any moved towards anniversary mods for the ZTPRE yet (and looking at the innards I'm not sure that there's room). Cheesy

With the Taboo Mk III and Mk IV and the 25th  Anniversary SE84UFO3 Monoblocks there's no doubt that a preamp improves things--these amps love to have a lot gain coming in, they take on a new full-bodied flavor.

Keep posting impressions, I know I'm not alone in wanting to hear more. . . .

Steve's amps seem to like higher voltage input for sure.  I don't know if the CSP3 puts a veil on things but what it does positively more than makes up for it in my case.  My guess is the modification reduces any negatives that the CSP3 might add.  Steve mentioned the total harmonic distortion at 30 volts is now much lower with the modifications.  I'm sure I'm well under 30 volts too.

Thanks for your repot regarding the CSP3 A-Mod Archie.  Mines going in next week.  Hate being without it but Ií think Iíll find it interesting to see what I can do with the ZDSD gain stage + ZR-2 + UFO2.
