Widzę, że temat drażliwy, ale nie mogę się powstrzymać. Dla zainteresowanych polecam ślepy test wzmacniaczy Richarda Clarka, w którym brało udział tysiace audiofilów i nikomu się jeszcze nie udało go zdać.

Oraz post Floyda Toole'a na zachętę:
Truth is that many years ago I thought that amps had distinctive sounds - until I did a proper level matched blind test. I had just purchased what was then called a "super amp" - something with more power output than was practical with tubes and first gen solid state stuff. I spent hours "hearing" things I had never heard before, feeling pride of ownership and of technical advances.
However because of who I am I had to test it properly. In precisely level matched instantaneously switched A/B/C/D blind tests, including my old amp and several new ones, nobody could hear any large differences - including me - and I let the test run for many days, inviting local audiophiles and audio salesmen in, returning to it, listening for long periods. I was really surprised, as were the retailers who routinely demonstrated "differences" in their stores! A couple of them had been participating in loudspeaker evaluations as well, and they stopped coming to my evaluations because - and they were honest in this - it got in the way of selling products. I absolutely understood.
