This is like asking what camera a picture was taken with. People spend all kinds of money on different camera bodies, but most people wouldn't be able to pick out a shot taken with a cell phone vs a $5,000 DSLR and few if any could say that image was created with a _______ camera.
Blind fold hearing test
How many of you could be blind folded or put in a room in total darkness and know what kind of speaker amp and preamp are being used. Another words if u came blind folded in my listening room could u tell I was using a Krell amp a ARC pre and B&W speakers? Not necessarily the models but more or less the brands. I would be the first to say for me it would be no. Would love to see how many of you could. Should be interesting.
