Thanks! I went to another dealer and auditioned the 703s. Very, very nice and for $4,300/pr I would hope so! Aside from a great bottom end they had very good 'presence' up front and crystal clear highs - does the M60 have the same feeling?
Then the dealer went "let's try something different" and hooked up two other sets of speakers - MonitorAudio RS6s ($1,400/pr) and RS8s ($2,100/pr). And except for a slight (very, very slight) reduction in the top notes I found them just as good as the 703s! The RS8 had a wee bit more bottom, but I could only hear it on one song where an african folk group had a singer that could hit about 21hz (I swear). Without back to back against the RC-50 it's hard to say, but that RS6 for $1400 sure sounds like a killer. The 703s did have a bit more 'presence' though...
