anyone who's skeptical of this type of thing should listen to harsh noise for an hour, then put on something pretty. it's like pressing reset on your ears. unclear to me whether the effects have anything to do with the gear itself, but it is very real and immediately noticeable.
OK...here's another tweak that really works
I recently recabled my reference 2 channel system. The upgrade in sound broke new ground in what I thought was possible with existing components. I had not, however, heard of the Matthew Bond Audio Cascade Noise Burn-In Disc - V. 2.0 until it was referenced in one of the fairly recent Forum Posts. More out of curiosity and the fact that I have had some very positive results with other assorted/sundry tweaks, I decided to give it a try. I have played the disc only a couple of times and am amazed at hearing a very real improvement in all aspects of the system and especially the glare that I really didn't know existed.
Anyway, I would enjoy hearing from any of you that has had some exposure to this or other tweaks of this kind.
