I too have used my VP100 with my M80s and very briefly with a set of M60s I had prior to the M80s, The 100 does a very nice job with dialogue, it only lacks a little smoothness and low end that the floostanders have, not to say the 100 is harsh or anything. Until upradeitis hits you should be good with the 100, I went 4 years with it till I picked up the VP150 and hopefully next year I will have the VP180.
