I've had my M80's for almost a year now and still enjoy them as much as the first day I got them.I never heard the M60's but if the are even close to the 80's there is plenty of bass to them.Maybe John K. is on the right track that you might be used to a bloated bass response in what you are used to.I have mine powered by a Rotel RB1080@ 200 watts into 8 ohm and 300 per into 4 ohm.I also believe that they need plenty of power to sound there best.Mine too are teamed up with a HSU VTF-2 sub, I already had it before I got my M80's so I probably would'nt have got a sub if I had bought the 80's first as they do sound really good on there own.
