UPDATE:  Listening to the Anniversary amp/preamp with the mystery speakers on old tried and true reference material from GRP, and this speaker design has completely re-arranged my head about the importance of projection.  All my ideas about skinny little towers that imaged like they weren't even there are getting shaken to the core right now.  It's a double whammy, because the they are letting me hear how good the Anniversary gear actually is, which I thought I knew but turns out I didn't.

I can see absolutely nothing will get done this weekend!!!  It's so insane to hear music like this on anything, let alone two watts...  unbelievable.  Since it's probably going to be awhile before I can say anything specific about the speakers anyone who wants to book a listening appointment would get forced into a situation where they would have to hear them and then be sworn to secrecy possibly all summer.

This is also my introduction to a new hi-end speaker manufacture, small like ourselves, who I have no idea at this point what kind of stability is there.  So far all the right signs are in place for a solid company with good ethics and great products, so I am having conversations with them to see what kind of availability might be had for this driver in the future.

As I listen tonight these speakers and amplifier make crystal clear the observation I've had in the studio when listening to 16 bit vs. 24 bit.  The 24 bit is smoother more correct.  The 16 bit has more slam and is sharper.  God bless 24 bit.

So as the evening continues... listening to "City of Stars" by Ryan Gosling.  At the ending I heard the female vocal lay down on the floor, stage right, and sing up to the male vocal who possibly had her in his arms.   This is pretty hardcore imaging when you see and feel that happen right in front of you as though you were setting in front of a 200 inch movie screen.

For those who stream...  I don't know about you, but I save my favorite tracks and then I create playlists of those tracks, usually always the first one being a demo playlist designed to wow the listener.  The process is simple, you listen to all of your favorited tracks and then pick the ones that are just too good to be true, stuff that is simply over the top.  That way when you want to blow someones socks off in a short amount of time you get the secret playlist out and let it rip.

Well I found myself making a new playlist tonight for the secret speakers, version 2, and after several hours have realized that almost everything I listened to I added to the playlist.  Normally with all other speakers, the items added to a demo list are about 1 in 4 or 5.  That should tell you something... that I'm not getting much sleep.

Steve, these updates are really fun to follow. You keep it very exciting. I can't wait to read and learn more.

Have you or would you consider comparing the ZTPRE with anniversary mods to the new CSP3 anniversary edition? I'm really curious as to the differences between them and it sounds like these mystery speakers and the 25th Anniversary Zen Triode Amplifier are up to the task.

Thanks,
Jim

So much fun!
I love when you get a new speaker design.

And this anniversary amp must be the best!

25th Amp is beautiful. 10 months in and I have stopped rolling tubes and tweaking...no need! My 4 yr old Ortofon 2m black needed replacing. So, instead of a retip I decided to go with something better...Soundsmith Zephyr MKIIIes.
Wow, only 10 hours on it and it is worth the price of admission. Plus I know it has not quite settled in yet.
I truly believe that, no matter the cost of the source, the 25th will keep up with anything I throw at it.  From what I am reading of Steve's posts above this more than holds true. It was a bit nerve wracking making the 25th purchase $$, but it was the right choice.
I need to get to Decfest one of these years just to A / B against my room. Wondering...."Can it get better" ....I'm sure the answer is yes!

Hey Ace, I'm curious about your new cartridge. What would you say is different compared to the 2m black? Is the output roughly the same? Or do you need a step up? I mainly ask because I love the 2m black and wonder what the "upgrade" would get me?

Sorry I know this isn't directly 25th Anniversary Zen Triode Amplifier content.

Jim,

Comparing the ZTPRE to the CSP3 is difficult because one is balanced and one is not. That means to do a direct A/B the ZTPRE has to be fitted with transformer-coupled RCA inputs and then it's output has to be run into a ZBIT. That means a transformer, the preamp circuit, and a transformer being compared to just a preamp circuit with no transformers.

So let's talk about the preamp circuit itself. The ZTPRE is exactly two CSP3 circuits instead of one, and it has solid state regulation instead of tube.  That's going to make the fundamental signatures between the ZTPRE and CSP3 the same. The solid state rectification, large caps, and torroidal power supplies in the ZTPRE make it more neutral than the CSP3 with probably most tube compliments.  

I can tell you that I use the ZTPRE fitted with the transformer-coupled RCA inputs just to make my RCA output sources sound better, and it does big time. I could probably spend 3 times as much on a source component and it wouldn't sound better. Transformers like these add dimensionality and a nice organic shimmer to the top end. My advise is don't listen to them unless you can afford to buy them because once you hear them you are wrecked. For example, when I remove the ZTPRE and run my balanced sources directly to the ZBIT it is seldom as good. Same is true if I run the RCA sources directly into the amplifier.  My ZTPRE has just become part of my digital front end, as well as the front end for two of my tape machines.  

As for the CSP325, it does the same thing as the CSP3, in that it makes music more juicy and beautiful to listen to with greatly improved dynamics, imaging and tone. All without getting syrupy or veiled in any way. The Anniversary mods and or the CSP325 does the same thing but with greater resolution so that it doesn't detract from the resolution of the 25th Anniversary Zen Triode amplifier.  Of course I'm sure it would sound wonderful with any amplifier be it have the same resolution or not.

Thanks Steve. I have a ZTPRE on order with the transformer-coupled RCA inputs, and anniversary mods. I wondered for a half a second if I should change my order to the CSP3 anniversary, but after your response I'm sticking with it. Sounds like it will be glorious.

Steve, this makes me wonder if one of your power amps might benefit from Transformer coupling instead of RC coupling of it's driver stage to the output stage.  Have you an interest in trying Transformer coupling?

Pursuit...sent you PM.  Will post in ZP3 forum when I've had more time with the Zep. So far I am very happy with it.

Certainly I have, yes.  It only adds $700 per stage and would require a redesigned chassis, power supply, and overall voicing to make it right if you used it in place of standard capacitive coupling.  By comparison a type II beeswax cap cost ten times less and are 90% as good.  Simply an issue of diminishing returns.  And that said, it would have little effect on the voicing of the amplifier's input signal since it is part of the amp itself.  We use the transformers to balance impedances between components and manipulate gain which is where the big boost to sound quality comes from.  This is what the ZBIT is for and why we use it.

I'm wondering if such an amplifier would be a success?
Everytime that Decware ups the ante on amps, (25th anniversary ect.) it seems that they sell pretty well.
How much would customers be willing to spend? I'm thinking maybe $5K??
It seems that there is a whole industry focused on chasing that last 10%, it might be worth a little thought.

I thank you Steve for the reply.

"We use the transformers to balance impedances between components and manipulate gain which is where the big boost to sound quality comes from."

Not doing those things, it does seem that an interstage transformer would be of less value to the sound.  
It is always good to get education from you.
Thanks, Brian
