I've owned the EPOS M22's and found them to be very articulate speakers, especially with voices. One major drawback I found with them was the soundstage, or rather, the lack of it.
I had these partnered with a Roksan Kandy MK3 amp and a Rega Apollo CD Player. As good as it sounded, it always felt like the EPOS was 'holding back' - that was my assessment of them.
They were great speakers nevertheless for the price, i.e., £950.00 a couple of years back. I believe WHF had a First Test Review of the EPOS M22 against other speakers and awarded it a 5/5 score (June 05).
I've often wondered why the EPOS M22i's are not included in the Group Tests - maybe someone from the team can answer this, but I would expect the M22i's to have been built upon the strengths of the M22's and made a lot better overall.
