I have heard 703s and M60s but not at the same time so I can't give you an honest comparison -- but I did buy M60s for what that's worth. People who have heard them together tended to feel they were "comparable" but not identical in sound.

M60ti, VP180, QS8, M2ti, EP500, PC-Plus 20-39
M5HP, M40ti, Sierra-1
LFR1100 active, ADA1500-4 and -8
