The magic here is M22s = smaller room and M60s=bigger room. Frankly, I would hate to have my life depend on the difference in the audio produced by the two. Jack is happy he made the switch to M60s, and as said many times, the choice is personal preference. Both speakers do better with a sub and the M22s benefit most, (I really like the SVS choice). I gave the M60s the nod because logics (read testostrone and bragging rights here ) told me "bigger is better" and I like the look of towers. Also, when you factor in the cost of good stands, the price difference gets closer to being a non-issue. The REAL driver for the decision was to avoid the old "what-if". The M60s are special and I'm a happy guy.
