Yes, they do.


No they B. don't. 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 doesn't matter which amp can go loudest, they both have to be level matched
and be able to drive the speakers without clipping.

Try it again under level-matched DBT conditions. Been there, done that
many times. Without LMDBT, it don't mean a thing.


Rubbish! I'm sorry but this is so much hogg wash, the differences were so
obvious immediately and the shop clearly would have preferred to sell the
other amp but had to agree the Denon had the legs. Besides I don't know
anyone that listens to their hi-fi in an LMDBT manner they just switch it
on and turn up the wick until it sounds right, that's what we did and the
Denon was better QED.

uhm, who does listen to their hi-fi in a LMDBT manner? that would mean switching
between 2 sources or 2 amps. The LMDBT manner is meant to provide an unbiased
comparison between different digital sources or amplifiers, ie to be used when
purchasing new equipment (or to perform experiments)

I also know that
amplifiers sound different depending on what you place them on, I don't
think this, I know it! (True story told before).

could you elaborate? I'm thinking of hum or other nasties that the amp picks up
from the surroundings (e.g. like placing pre and power amps too close to each
other, stray RF sources). Or does this indicate poor amp design?


What would you have people do, buy the cheapest amp that had the
facilities they need and ignore the sound?


well, if the amps sound the same and are capable of driving the speakers ...
