I have Rowland Model 102 (smaller Icepower) and used to have AQ Indigo speaker cables. Since Icepower reviews complain about "not very round" sound (lower midrange) I selected speaker cable with a little pronounced lower midrange - Acoustic Zen Satori Shotgun. Sound is much fuller now. There is this "chestiness" of male voices it was missing with Indigo. In addition sound is more "silky" - probably general improvement (much better cable). I'm using AQ King Cobra Interconnects while planning to buy Acoustic Zen Silver Ref II.
