GaN amps: Peachtree or LSA Voyager?

The only rational and real debate that can take place is on the objective facts: performance, design, execution, etc.

Intelligent people don't debate subjective opinions.

This appears to advocate objective excellence as the only path while eschewing any validity to subjective opinions. Perhaps in the framework of this discussion that is a valid argument, however, when considering components with larger (measurably significant differences), it would be absolutely necessary to debate or at least discuss subjective opinions as that would be necessary to correlate objective changes to subjective impressions.

This topic is like 10 other topics on Audiogon. No one disputes that we all differ in what we like. The issue in this topic and every other one like it is that some people make claims that "something" is audible but never prove beyond their personal account that it is audible. I have enjoyed Atmasphere’s posts over the last few weeks as he is clear and concise and relates specific outcomes for things we hear to how his or similar products operate. To me that indicates someone who understand what they are doing and understands the problem and solution. I have not seen him advocate "what is right", only what the result will be.

@kuribo perhaps you are advocating too hard that an amplifier must be technically perfect. Alternates to perfect can sound better to some. However, I understand also your general frustration.

@ricevs it is good to have positive customer feedback and especially if that is the primary feedback. However, while I was cramming on "how to run a business" before we sold out to the highest bidder, I remember reading in a strategic marketing book how businesses can stagnate because they think they are producing the "right things", but in reality, their customer base is exclusively those already predisposed to "what they are selling". Meanwhile, they miss the vast majority of the larger market who has no interest in what they are selling.

I clicked on the topic purely out of "academic" interest in GaN, but I can’t say this topic convinced me it is anything worth my dollars at this point.

@atmasphere

Is there a reference for the -105db? That sounds excessive. Do you mean at a single frequency or all frequencies (I assume 10KHz and under?). I see an often quoted limit of 0.1% as being the absolute lowest than can be detected, and I think normally much higher.

@snapsc, would that not be easier to accomplish with DSP?

@snapsc 

I can't see why it would not be possible. Distortion is just harmonics of the original signal. I expect there would be some complexity. The distortion would be influenced by signal level and I expect frequency. I am sure there are lots of people who could do that if they put their mind to it.
