You may be right or you may be wrong.
However when such respected figures as Peter Walker, Siegfried Linkwitz, Peter Aczel, Alan Shaw and many others all allude to the same opinion regarding amplification, then perhaps we ought to respect that opinion at least?
In my experience with amps ranging from the NAD 3020 to the Naim 32/110 the amps I have owned have made insignificant sonic difference.
In fact my last 2 amps, a Magnum IA 170 and a Creek integrated sounded uncannily similar when I was able to swap one for the other.
This was a disappointment as I was labouring under the illusion that the far more expensive Creek was a vastly superior amp. I had previously read that it had a more sumptuous, warm and rich sound.
As we know the human perception system is subject to all kinds of illusions, yet it's still a disconcerting feeling when it's demonstrated in such a direct fashion.
