Technical and scientific discussion of amps, cables and other topics.

RE: That clears up a lot!

Thanks. I'm very glad to know that article has made its way onto the net. I kind of hoped it would generate some interest, at least among those who were arguing about whether power amps ever sounded provably different. This test answered that in the affirmative for this particular case, and offered predictions about what future cases might turn out the same way, or not.
(As the article notes, the same two amps with a different and easier speaker load became sonically identical, or nearly.)

If it actually led people to measure the effect of the impedance curve of the speaker, whether during design or in reviews, that's cooler still. -- EBM
