In reply to:
I will go ahead and order the M60's along with the center
I think my first question when I joined these boards was whether or not the M60s "would still be able to sound delicate on acoustic guitar" in a small room, or did they just need a bigger room to "stretch their legs"? I was assured that they would do fine, and they do.
I've owned some of the old classic DCM TimeFrame 600 panel speakers (when DCM had higher-end lines) and with them, experienced speakers that really need lots of power and a big room. The 60's in comparison have offered everything I was looking for: sheer power when required but a delicacy when required as well.
You'll be happy with them!
