I've read that previous lines of ML's when powered by PS Audio's power regenerators did not like the Multiwave setting (causes the ML's to shut down). Since I already have a P600, I decided to try it with my Vantages and discovered that not only does it work now but it improves the sound dramatically. The bass goes A LOT deeper and is better defined. The soundstage became much more dimensional. Just about everything else got kicked up a notch (BAM! as Emeril would say it). Anybody else have similar experience with their Logans?
