I have a different experience than Jallen. I have a balanced system and have found just as much difference in the sound quality between balanced cables as the RCAs in previous systems.
Dennisb, I have a Meridian G08. The best cable I've found for connecting it to my Rowland preamp is Kimber Select KS1130. It is a silver cable but doesn't have silver's characteristic brightness. It is quite neutral tonally, but has lightning-fast transients and incredible resolution. It may be a bit more expensive than you want to pay ($750-850/1m used) but is worth it. One caveat, it takes about 200 hours for it to settle down and assume its neutral character. It sounds a little lean until that time.
