I've been fortunate to have had friends lend me tweeks, high priced wires, IC's, bricks, stones, elevators, and the like, and NONE of them made any difference in sound at all. I'm just happy I spent my money on better equipment. Adding subs, a different set of speakers, eq's, going from SS to Tubes and things like that will make a difference in sound, but to me all of the tweeks mentioned are just a ripoff. Nice to see RW got a refund, and didn't have to learn the hard way, or fool himself into thinking the tweeks were working. Just enjoy the stereo.
