If you can't track down anyone who has heard these two speakers side by side, it may be worth your time to order the M60s and find a Paradigm dealer willing to let you do an in-home demo with the Studio 60s. Most reputable dealers will let you do that.

In addition to satisfying your curiosity, you'd be satisfying ours, as well -- if you reported back to us about your experience (which of course we'd fully expect ).
