I have just bought two REL s-500 subs. I have 2 systems: Linn Klimax DSM feeding NAP 500DR into Dynaudio Heritage Specials; Linn Klimax DSM feeding SPL Performance monoblocs into Dynaudio Confidence 20s. The subs are probably going into the Confidence 20 set-up. I am a bit skeptical about spending the extra on the Baseline Blue over the cables supplied. I would welcome your input. Sorry to be a pest but they are coming tomorrow and I could get a deal, I suspect, if i buy now so early advice would be welcomed
