Excellent idea. I was going to scrap it, but makes a great deal more sense.
I don't think the premise was that all amplifiers sound the same - rather, that any two amps that measure the same, under the same measurement conditions, should sound the same. I.e. there isn't some other ethereal / unmeasurable property that gives amps "character".I therefore conclude that not amplifiers sound the same nor do they sound the same in the same brand.
Actually: We've concretely established that people hear exactly the same thing because two properly built and not-overdriven amps are identical in output to a specificity higher than human hearing.We know a lot about reproducing sound, a lot about how amps work, and a lot about the psychological and physiological aspects of perception. What we have not done is addressed in a systematic manner the reasons that people hear what they do.
Which, on properly built amps not driven to clipping have been clearly eliminated time and time again by blind comparisons.While the vast majority of differences of many types can be explained by placebo, expectation bias, and other "soft" variables, there are also some clear possibilities for differences to exist in the hardware.
No. We cannot. Unless at least one amp is being over-driven or is improperly built (adds coloration). That's been proven time and time again by testing.Read more: Can we really hear a difference between amps? - Page 3 - Home Theater Forum and Systems - HomeTheaterShack.com
There are several options.I am not sure if we are talking about just home audio and pro amps? I have definitely noticed a difference in amps before when speaking of car audio (I have had a slew of car audio amps). The only difference that was clearly audible was when I was running Linear Power brand amps. The sounds was (without sounding like a fan-boy) all those cliche attributes. The bass esp. was extremely articulate.
There are several options.
1) It's imagined. Let's just assume it's not imagined because we'd need a DBT to determine if it was.
2) The other amps are underpowered (please remember that blatant lies regarding power are rife in the audio amp world). Realistically, a very good car amp might be 25WPC.
3) There's EQ occuring in the amp you like.
LOL Sonnie, the Zipser test is my fave example of the DBT working correctly. I also agree that the gear ideally will impart no signature at all on the signal passing through it, unless it is meant to, eg EQ.Is it not the desire of the audiophile to have electronic equipment which does not alter the sound?
Your thoughts and comments will be interesting.
