I had a chance to listen to a pair of Revel towers (maybe F12 but thought the number was higher) that were for sale used in a local audio store. Roughly same configuration as M60s except slighly larger woofers IIRC.
Didn't get a chance to do a direct comparison, was thinking about taking them home and giving them a listen (ie they sounded decent) but dawdled and someone else bought them instead. Initial impression was a bit less bass than the M60s and with that came the slightly "tighter" sound I associate with smaller speakers on a stand.
I don't have much luck comparing speakers unless they are in the same spot in the same room though... if the room is good or the music is good I tend to think the speaker is good too. Even then I get stuck in the "ok they clearly sound different but I have no idea which one is right or even closer to right" trap.
I'm still fiddling with the listening room and still hearing big changes even though the speakers are always the same M60v4s. I hadn't been happy with the sound recently then remembered I had temporarily put the glass-topped coffee table back. Removing it made a huge difference in both imaging and soundstage... started hearing sounds outside the speaker pair again, including some seriously WTF?? sounds *way* off to one side or the other. Soundstage width is one of the areas where v4's seem to be significantly improved over the ti's in my HT system.
It's amazing how little things make a difference - I had been reading a hard-cover book and realized that even having the book open on my lap made a small but noticeable change in imaging. I probably need to replace the big overstuffed chair with something smaller as well.
Makes you want to go back to headphones
