After reading this entire thread, I'm glad I don't mess with all this stuff, Everything runs fine here. If it ain't broke stop messing with it. Sorry you folks get caught in what I see is a trap to buy/add more things you don't need. I think some companies prey on O/C personalities types (most of us in audiophile land), just my 2 nickels. I'm not flaming any of my friends here, just sayin'...
