I think you were the one with both? Any more impressions? How much of a difference would you say there is in sound quality for example 10%, 50% ? Also how much of this is down to the frequency response? because I would possibly prefer the FR on the Brainwavz as I have problems with bright treble. Overall yes I might try one of them, but going to see what Quad say about out of warranty service, because that might be something that would make them worth the extra over the Brainwavz, as well as obviously the sound quality depending how much difference there is.
