Can a Amp be "timeless" and compete with todays amps?

@jjss49 

+10 for your well stated comments. 3 weeks ago I attended a classical music performance featuring a cello and piano duet. This past weekend my daughter and I went to a local jazz venue . Both experiences were quite different obviously but what they shared in common was the high degree of emotional involvement and listening joy. Both outings were simply wonderful. 

I believe most of us who love music strive to obtain some reasonable degree of this engagement and the stirring of emotions through our home audio systems (At least that's my objective). Newer audio technology  may certainly have the potential to achieve this goal. Time and listening will tell. 

I just do not buy the idea that by virtue of being the next new thing it  by default is superior to what already exists and is performance proven. I've heard the VAC Renaissance amplifiers and know it is quite capable of providing a highly emotionally engaging music listening experience. High NFB solid state may or may not. Actually listening is the true arbiter for better or worse.

 New is not necessarily better. Remember that it is promoted that way by the audio media to help perpetuate the hobby. That's a fact all hobbies go through fads and it gets promoted that you need this not what we told you ten years ago. Get rid of your old stuff buy new! I love currently the idea of stereo pieces that have upper end sparkle. I have listened to some of the pieces that are written about in that way and thirty years ago things like that were called bright! And we're to be avoided. Now it seems like bright is being promoted is that because the average audiofile has gotten older as the hobby doesn't seems to attract the you g anymore and us old audiofiles are losing our high frequency hearing? That's something to ponder. You see the exact same thing going on in hunting magazines the rifle calibres they promote now compared to the past. All hobbies have this promotion directly for sales. 

The other thing I would ask the original posted are you sure when you send your amp back to be modified it will be better? You might get a surprise and that you don't like the changes. Be careful.

so you are ditching everything you have espoused (if not self-promoted) on this forum for twenty years in order to go all-in to self-promote your new Class D amps.

Wow. Did you see me promoting our class D amps here? I simply stated the underlying engineering issue that any designer faces if they wish to advance the art.

I'm not stating anything in conflict with anything I've stated before. You'll notice that our OTLs are zero feedback- that was done because applying enough feedback to avoid brightness and harshness was never possible. Personally, I find harshness and brightness to be the biggest sin audio can commit. So they are zero feedback, class A(2), a single stage of gain, all triode, fully differential and balanced from input to output, and output transformerless. This was done to eliminate as many distortion sources as possible. It worked- the OTLs have dramatically lower distortion than any SET, are obviously more transparent on that account and have garnered a lot of nice reviews and awards in the high end press. So we know they work, as if our ears weren't telling us that:

Precisely my point , use your ears and decide. If you genuinely believe that the new betters the older alternatives then case closed as far as you’re concerned, I get it.

Let’s simplify negative feedback = taking something ( the AC audio signal aka music ) that has ALREADY happened, flip it around out of phase ( that’s the negative part ) and feed it back into the input where something new and unequal is happening ( unless you think sine ways are music )… then apply some critical thinking….

I will point you to this, the Amp I have is zero feedback design.

RENAISSANCE SEVENTY/SEVENTY Mk. III Dual Mono Zero Feedback All Triode Power Amplifier

FWIW. Attached is the PDF manual.

@retiredfarmer Yes, the Mk III updates were in essence the last version of this amp and preamp, so it is improved upon in their design, their finest version of them if you will.
