[QUOTE="dipitydoo, post: 4110099, member: 567383"] As already stated, controlled tests will reveal no audible differences in sound. IMO, there are much better ways to improve the sound of the audio system, and trying to improve on it with the use of expensive components that do nothing further than to continue to greatly exceed the threshold of audibility is silly. But if anyone's still up for wasting energy, know that just about all of these 'class A' amps are really class a/b amps with a higher bias in class a. I've seen a few that work in class a till around 20 watts before switching to class b, and perhaps there might be one or two that is full class a. But other than that, just about all others are your basic class a/b amps, which is just fine, in fact better than class a amps, for real world usage. [/QUOTE]
