Well, I did it. I slid my MA6500 and MSD4 out of the way and slipped in my Gas Son Of Amzilla with a Theobe pre for my ML Sequel2's. Big Big difference. More dynamic and tighter base, much better imaging and power to spare. The Mac was laid back and the base was muddy. The Mac worked well with B&W's, even brought out the best in my maggies, but lagged when it came to the ML's. The Gas is much more cleaner and detailed, with crisp highs especially while listening to the blues. I hav'nt spun any vinyl yet, just running the Apollo for now.
