I too had the M22's paired with a Hsu VTF-2, and made the switch to the M60's.

Listening to music, I set the M60's to small and have the crossover set at 40 or 60 (depending on what I'm listening to)

For movies I bump the crossover up to 60 or 80.

I'm not a huge fan of tons of bass, and I also live in an apartment, so taming it a bit is always good karma.

As much as I love my M22's the M60's are that much better. You won't regret making the upgrade.
