I have in mind for a long time now trade my M80 for a pair of M22 and 2 EP400 for a stereo listening.

How great that would be i bet !

I would personally just stick with the m80's for stereo listening.... However I don't listen to much music that plays lower than the m80's can play.

Get a Buttkicker to pick up where the M80s leave off.

Much, much cheaper to stick with the M80s and they also can play much louder than the M22's. I had a little EP400 and could hardly tell it was on when running the M80s, at times it was even drowned out.

EP400 isn't that much popular, I've always been intriguing.

You are corect in pairing the 400 with the M22's it does sound incredibly good, but as you already have the M80s, I wouldn't sell them off to get the M22/EP400 combo. The M80s are a better speaker IMO. If space was a concern then yes going to the M22/EP400 set up would be a very good substitute for the M80's, especially for a music only system.

Well thsi is just a crazy idea of mine but i wont do it. But i've always been curious about this setup (M22 and 2 EP400) for music listening and even movies.

Well maybe one day, since then i do love my M80.
