I don't think legacy brands are M'a issue. It's the new girl, with the better ... that has everyone looking. :-)

By this I mean, M pretty much handed trinnov the high end home theater market. It was looking like Dirac and then out of the blue comes a French beauty called Altitude. No one wanted the Gentle Art of room correction". I know four people off the top that used to own 861's, that are now devout Trinnov owners. Trinnov is what M used to be. Cutting edge with great service.

I cannot comment on DSP's or other bits. Never understood the allure of DSP's. My time with 7200's didn't blow me away.

Other brands Ayre. Good, but changes products too frequently and doesn't support legacy hardware like M. I haven't owned before, but my interaction with Aesthetix has been remarkable and demos I have heard put them in the best I ever heard category".

Imagine what would have happened if M didn't buy Sooloos! I wonder if M would have ceased to exist years ago?
