Hey all, I currently run a ma6200 (and really dig it still) but have a opportunity to buy a ma6500 at a decent price. Can anyone tell me what some sonic differences may be with these two amps? I know the 6500 has more power but is there a much better "soundstage" with this amp? I have Cornwalls and a newly acquired Mofi Ultradeck TT (which is awesome!) Anyone ever have both of these amps at one time or another?
