A month or so I posted about making up my own interconnects, and how I was basically surprised they worked at all, much less all of them worked (I made 5 identical cables). They worked.
But I had this nagging feeling, knowing who had done the work, that they weren't done professionally. While ordering other cables anyway, I bought a 5 pair set of the premium interconnects from monoprice.com
I connected them last night, and immediately noticed that my system was playing louder, then went back into the AVR setup to re-level the speakers. I discovered as much as a 3db boost from using the commercially available cables. A couple of them had smaller increases, but across the board, I had to drop the levels in the AVR on all speakers to re-level everything out to my standard 75db reference.
How about that? Just proves that I suck at some things.
