Im curious if the people who voted yes actually arrived at their conclusion using blind controlled listening tests.\n\n\nI voted yes because I've heard an amp not be up to the task at hand. It was just a subwoofer (pro audio), but when we changed out amps me and the other sale guy looked at each other in shock because we didn't expect the sub to perform so much better. That told us that the amp we had in use couldn't handle the load the folded horn sub was demanding of it, even though its spec sheet said it could.\n\nSo, they do sound different if a speaker demands more than the amp can provide.\n\nNow, would two amps sound different if they BOTH could easily drive the speaker? I have no idea, but I'd lean toward no. I'd love to participate in a test to see if I did in fact hear a difference. Would be a neat exercise.
