And I ask again what you meant about performing room EQ - was that during the amp comparison?
I'm more than happy to continue to be the lighting rod on this with one qualification: I've simply stated my experience. I think I've likewise been pretty clear that even though I've personally experienced different sounds between amps in my setup I've been pretty clear that I'm very interested in the reason
for that experience. Was it psychoacoustic, was it some possible mismatch, was it simply the stellar sound of the Ultima Salon2's (remember guys, not talking about crappy equipment here). Who knows. I can only relate what I experienced, that's all. That's the data. The interpretation
of the data is the reason/explanation why there was a perceived or real experience.
I still have not seen a true, peer-reviewed study confirming or refuting about amps and their sound.
I was very interested in the links you posted. I hope you had a time to look at some of them--the one by the Boston Audio Society to me was the most interesting.
The ramblings and purported statements of posters in a forum can only really be taken as anecdotal at best. Moreover, one of the posts makes a claim about audiophiles being the subjects. Wait a minute here. Revel and Harman go to great lengths to train their listeners
before putting them in their double-blind setup and then after training those listeners then need to pass tests to confirm that they are accurate subjects.
Personally, i'd absolutely love to participate in a double-blind test of amps that is properly controlled. That's the way tests should be.
I don't have a predetermined goal to see the debate go one way or another. Rather, I'm legitimately curious as to the reasons why. My tendency (bias) is to conclude given the current data that my experience was based on the different sound of the amps. If it was psychoacoustic, that's cool too.
Ironically, I'm getting the sense that there are some who have very strong convictions if not inflexible convictions one way or another. That's great but the convictions and bias will get in the way of what you're looking for. Are you simply googling articles that "prove" amps sound the same? Are you simply googling articles that "prove" amps sound different? That's not science.
I've very clearly stated what the general issues around amps are and moreover the question about audible relevance of the differences in measurements. End of this month, I'm looking forward to putting a few amps to the test and I'm looking to see if I have the same experience with those amps as I previously did. Funny thing? Emotiva is telling me about the differences in sound between their XPA-1L and the XPR-1. Ah, just have to love it.
Perhaps we can have some others test out some amps and post their anecdotal observations.
