Ludovic, I don't know. These idiots have obviously never had an Acoustat
TNT-200 a Hafler XL-600, a Parasound HCA-2200, and an Odyessey in their
hands. With different circuit topologies, they sound markedly different,
yet
none of these amplifiers have ever been labeled as "improperly
operating",
or "defective", by anybody.


The differences between stock Haflers and ones properly modified with
reinforced power supplies, internal shielding and bypassing, and other
relatively inexpensive mods are noticeable to all but the most casual,
or deaf, listeners, and the modified ones "sound better" in the opinion
and judgment of _every_ listener, as far as I know, experiencing the
comparison. Based on this example of unanimity, in the perceptions of
listeners, despite the relatively small change in measured performance,
I think one may reasonably conclude amplifiers do sound somewhat
different, and some sound better than others, at least in the
perception of an overwhelming majority.

If the comparisons weren't done blind then you know they are worthless.
