GaN amps: Peachtree or LSA Voyager?

@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.

Where have I advocated for technical perfection? Where have I said that some people can't like whatever they want?

There is no such thing as technical perfection, but there is good and bad design practice, as well as outdated tech.

Everyone has and is entitled to their own opinions. When people start claiming they know what is better or best for others, then the bs meter starts ringing. Especially when they offer you better or best with a price attached and tell you it's not measurable and has no scientific basis, just "trust them"...

 

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.

@kuribo , if you were going to buy now a class D amp, which one(s) would you choose? Or, do you think that much better class D designs may appear in near future, and hence would you rather wait until then? 

Current products by Purifi and Orchard are beyond the limits of human hearing as far as distortion is concerned. The limiting device in the playback chain is not the amp, it's the speakers and the room. I would advise looking into Purifi and Orchard with state of the art tech and performance and then turn my attention to other links in the play back chain.

You can't go wrong trying out the AGD amps but you may end up with the Gran Vivace!!!!!!!

There is a mountain of scholarly research dedicated to the effort to correlate subjective opinions with certain audio objective measurements. The short answer is in certain instances general correlations have been found but these have little predictive power on a personal basis. In other words, you might find that 70% of those surveyed prefer x but does that mean you or I will prefer x? Not with any certainty. Ultimately, it's always a personal decision and no one can tell you what you will prefer with any certainty.
