Comparing amplifiers as Jay was doing means little , not only because Synergy matter, but because the impressions of an amplifier are not only gathered through many other components synergy it is listening through a Brain/ears room and with a room acoustically controlled for specific ears or not...

Putting panels on a wall is not the same as creating an acoustic room to serve a specific audio system for some specific ears and not another... Small room acoustic is not great Hall acoustic by the way ... Two completely different applications of acoustic laws... Size, geometry and topology and acoustic content matter , then a 13 feet room by15 and by 8 foot for ONE listener spot has nothing to do acoustically with a concert Hall for a crowd ...
Gullible people think that amplifier choice or dac choice or even speakers choice matter most than the room installation choices... Then they are ready to put 100000 bucks on an amplifier choice and 200 hundred bucks on few panels and call this acoustic job done.... After that in this same room they compare with the same components another amplifier and decided they can pick for us all the better amplifier for all ears/room and for all other existent pairing components...
They sell amplifiers, knowing it or not , most reviews are selling publicities; i trust only average users reviews and in great numbers not singular one and only for vintage products because they had been tested by many not few reviews for a very long period not a very short period and sometimes vintage are mythical products not new hyped one which will die way before being mythical good one...
And audio wise people look for the best ratio S.Q. / price not for the higher price tag thinking that higher the price better the sound will be...
