I received my M5HPOW today and I must admit, in the relatively short amount of time I have had to do some critical listening, they sure sound quite a bit different from my old V2 M80s which have been reassigned to the archives. I cranked them up for a short span and they had little problem handling it.
My only issue(if it is one)is that because they are on the wall along with my VP180OW which is under the television in an LCR configuration. because I use my system almost exclusively for video, the M5s are located quite a bit above my listening position creating the situation whereby it goes against the conventional wisdom that the LCR tweeters should be lined up as closely as possible. Of course, in this set-up, it is impossible. I will be putting it all through its paces this evening with a movie on my player to hear how it all sounds. I guess there must be something in the design that negates that conventional wisdom.
One thing for sure, it is nice to have the extra floor space.
