Yes, they do.

No they B. don't.

Sure they do - why wouldn't they?

Another example, My Yamaha amp (recently retired) always
sounded hard and harsh to me, I purchased it from a box shifter as it was
a good price and I fancied a dabble with surround sound. On swapping to
the Av8/P7 the improvement in sound was staggering and it mattered not
which was played the loudest the AV8/P7 blew away the Yamaha by a good
margin.

It probably had high HF IMD, pretty common in that range, and I
suspect that was what gave away the AX-570 in my own tests. OTOH, if
you haven't tried that comparison under *blind* level-matched
conditions, then your opinion is not of any real value.


SNIP SNIP.

I've certainly measured amplifiers that are almost identical into an 8R
load, but do sound different into speakers. The truth is that the amps
are not equally good. If you measure the intermodulation when driving a
reactive (imitation speaker) load then the differences emerge quite
clearly.
