For a while I had M-700u. Great amplifier.
Over time I noticed lack of power and grip with my SF Guarneri Evolution. A feeling of compression and narrowing of soundstage. A feeling of wanting more of everything.

Then comes M-900u. Wow.
Much better. Freshness, purity, ease...
Better control, silky high tones, deep bass and playful soundstage.
Late night listening is a pleasure.

If you can, go for M-900u.
