Well - could anyone tell me where to find the blind tests? A quick search finds many references to such tests, but no actual, you know, links to reports of the tests themselves.
(well, there's a second hand description here:
http://forum.ecoustics.com/bbs/messages/1/18030.htmlwhich might lead me somewhere eventually).
The power requirements are one thing, and that makes perfect sense. But within the limits of a particular reciever, I don't see a *necessary* reason for noticeable differences in sound quality.
Show me the data, please!
