Atma-Sphere Class D… Amazing

A well designed shootout among the leading or most popular class D amps would be very interesting, but getting conclusive results on such a highly subjective thing as how things "sound" is always problematic.

That leaves one to merely leverage both the two tools one has at their disposal to decide.....what they read including specs then always most importantly in the end what they hear.

Since everyone hears differently and also has unique goals and preferences, there is no pressure for anyone to agree with another.

At the same time, in lieu of objective measurements, no substantive conclusions regarding what is "best" or even "better" can ever be made. Each will make that determination based on the factors that matter to them. Measurements may or may not even matter in some cases.

As many trade publications and review's by professionals and laymen have illustrated over the years.

@mapman Measurements may or may not even matter in some cases.

What are the cases in which measurements don’t matter?

as @mapman says, all measurements, reviews, user comments, seller and dealer claims are neither here nor there

they are all proxies, good bad or indifferent, for how any item will perform in your own system, whether it will please you, improve the sound of the music you hear

want to really know? have to pony up, try it, listen intently, compare rigorously fairly, be honest with yourself

nothing else matters, it is all to bait the hook, so to speak... arguing is just a waste of energy time and bandwidth

different fish here snap at different bait... no one really cares what anyone else will bite at

What are the cases in which measurements don’t matter?

The ones that come to mind are:

1) the published measurements are not sufficient or accurate enough to be useful

2) The user does not know how to properly apply the measurements

3) The user simply does not care and prefers to rely on other means to make their decisions.
