The MA6900 is an absolutely fantastic piece of equipment. I have listened to it enviouly at my favorite dealer for quite a while since I can't afford it just yet. It has delicate envelopping highs with strong tight bass that is perfectly weighted as if it had the best of tubes AND solid state. It makes you feel the music. I agree it beats the Levinson 383 as I have listened to both in AB tests several times. Since hearing the Mc, the Krell 300i is shrill. The 6900 is incredible in all regards - I can't wait to get one.
