So, who is planning to upgrade to a Pro?

[Confused]

I think that Quad, those terrible British amplifiers used to only use measurements for their amplifiers and never listened to them to test either.

Goldmund too I have been told.
The problem with listening evaluation is that the placebo effect means that it is quite possible to hear a difference when there is none.
I have listened to music with Mathieu extensively as well as discussed many technical aspects over the last 5 years. I would trust his judgement 1000x more than any of the opinions I see frequently on hifi discussion forums, personally. Many of them verge on the lunatic.

No, the human brain is an infallible piece of measuring equipment and never makes mistakes or confuses anything, a little like HAL.

Well my brain is fallible & sometimes confused, but it did listen to a Pro and it thought it was one of the best things it had ever heard.  That's all that matters to me!
