I have heard from some who used the VP100 with M60 or M80 that the timbre match and overall sound quality were noticeably improved in going from VP100 to VP150. This was the basis that I decided to try the VP150 with the M80s. Unlike drew88, I have not been disappointed at all. In fact, I have been very satisfied with its performance, and my sense is that the vast majority of owners are very pleased with the VP150. I agree fully that there are many factors that influence a speaker's performance and that you should consider evaluating it first-hand in your sysytem.
