Pass ACA Class A Power Amplifier Review

The lack of logical reasoning skills here is astounding. Why would your reasoning only apply to the ACA and not the LA90?

FWIW, I bought the ACA kit as a fun project to do with my then 9-year-old son. Never got around to it, so got a local guy to build them for me. They've sat on a shelf gathering dust since.

Meanwhile, I'm very impressed with the LA90 - got five of them!

Nobody said it would…

A lack of comprehension skills too!

Wouldnt be surprised if you enjoyed the CA# over the LA a bit more.

# CA stands for Crappy Amp.

Not at all. One does just not follow from the other.

Enjoying A over B does not mean bias only applies to A or B.

In any case, you totally miss the point: it was about having a reference, and you say there isn’t any. Any my argument is that you do have a reference, unconsciously. This is a wholly separate argument.

Why do you think that?

Because technically it IS a crappy amp (looking at signal fidelity).
Fortunately human hearing is even crappier and an amp would have to be really crappy to sound crappy and some may even prefer it..

I recommend you read Floyd Toole's book Sound Reproduction, Chapter 17 specifically. Best to purchase and read the whole thing!
It will certainly help your comprehension of why people tend to chose equipment based on subjective observations over objective reality, how people hallucinate differences in gear that sounds the same, and what factors that often lead people to chose gear with worse performance. The comments that you said were nonsense are extensively researched, and discussed in the book by Toole in a way that is easy to comprehend, even for non-technical.

And there is absolutely nothing you can do about this.

except do a double blind ABX test.
