Luc, that is perfect, try the M22s with his sub, now it won't sound exactly like it will in your room but most likely close enough to give you an idea of how the M22's compare to the M80s and all with the EP600. Just note the M22s will need to be put on stands to compare them properly with the tweeters at usual listening height/ear height, otherwise you may end up with a scenario like mojo and I did the first few times we tried them at his house, the M22s were indeed very much thinner than the other speakers. The last time I went over with some proper stands the M22's performed much better, the thinness was gone and when combined with the EP600 sounded very similar to the M80s with the sub. Good Luck and good listening!
