Are future improvements in Amp/PreAmps slowing to a crawl?

While an actual opinion on what it sounds like might interest some, a few of us are genuinely interested in the technical claims he makes. The world is full of decent sounding amps and gear. The world isn't full of 100% distortion free amps. We wouldn't be having this discussion if Roger just said he's built a very good sounding amp. I'm not interested in hearing another very good amp. I'm interested in hearing a perfect amp, which is what he's claimed. I've never heard a perfect amp before. I think it would be presumptuous to assume I'd like a perfect amp. It's entirely possible I wouldn't. I want to see truly perfect measurements under the most grueling load so that when I listen to it I know that what I'm hearing is the sound of perfection. Only then can I decide if I like perfection. Since I've never actually heard perfection, but I have heard plenty of very nice amps, just listening isn't going to tell me if I'm hearing perfection because I have no idea what it sounds like.

With all due respect, telling people they just need to listen to understand the technical claims is the same thing as you saying "My word is the only proof you need to believe my claims". 
Trelja, I am interested to hear what you think of how it sounds. Please move forward with making this happen. An observation of just the preamp and then one of both amp and preamp together would be good, if you can work that out. 
kosst,

You keep talking about power amps - I'm not.
The core building block that is the "cloning amp" is found in phono stages, line stages, power amps (as the voltage gain) and dacs (as the analog output stage) the power amp will not be "perfect" when driving strange loads. It will successfully drive 90% of speakers. You may have some interaction that is introduced by the amp/speaker coupling/matching.

I have been talking about the amplifier process which is the entire chain of components - not just an amp. This is why I offered to have you listen to the line stage.

Besides I'm sure there are perfectly bad sounding power amps that can produce a KW into 2 ohms or have the perfect square wave at the output - so what?

On the one hand you are saying the specs don't mean anything as far as the sound of the amp (tube amps measure poor but sound great)
Solid state amps can measure incredibly good but can drive you out of the room when you listen.

In other words perfect specs do not mean a perfect amp.
If you examine the core H-CAT amplifier [stage] it has perfect specs and zero distortion. The output stage needed by the power amp to drive the speakers will do its best to maintain the purity that drives it. The power amp has no overall feedback loop (from output to input).

The core process uses tiny amounts of phase correction that can be considered "feedback" because it is a countermeasure but it differs so much from the classic negative feedback because of where it is in the circuit and how it is implemented.

That's not what I said
The only way to understand what I have been trying to share is by actual listening.
That's what I said.

You won't gain any technical insight by listening. But you will experience the acoustical result of the process. It is the experience that I'm trying to share.

teo_audio,
Can you enlighten me on the time/space 3d reality issue ?

Thanks
