Interestingly, the 590 and 700u share output transistor topology and have very similar damping factors.
The m900 however uses 2x the number of transistors per channel, and cuts the output impedance by half.
As I wrote before, the issue I was most worried of is VERY easy to hear. The OP should have no issue at all judging for himself.
