Well, what is it?
When playing full range,
1. Amps made no difference?
2. Amps made slight difference?
3. Amps made a recognizable difference?
I say full range because I think most of the difference is in the low end but what do I know, I've an ati 1506 sitting in the closet unuse waiting for an seos project.

Wow great thread.

If you read the thread you saw that a mistake was made so that all our results were incorrect. The next day we did it again with 4 amps and could not tell a difference between them even at higher volumes. We did not test it full range since none of us runs our system that way, but it would be easy enough to try. I heard all I needed to when I couldn't tell the difference between a 20 watt T amp and an expensive 2 channel Emotiva amp.

we need to repeat this test sometime.

Indeed. I'd like to participate.

Where are you these days? We miss you.

We need to repeat this test after the first of the year.
