Thyname,

I think you have the same setup as i do. One thing i think most people including myself forget is to treat the listening room (room acoustic). I have just finished my listening room by placing acoustic foam from foambymail.com to treat first reflection point on side wall , back wall and bass trap to all four corners of the room.

I must say that bass is much much better , tighter on M60 and i'm happy. I originally thought M60 does not do any good on bass, but I was wrong....

Anyway, room acoustic is a must.
