Yes I am beating the same old dead horse, but I am about to invest in M22s and return my M3s - or not.

I have heard the difference between the M22s and M3s described as slight and as significant. I was wondering what people thought?

Bass should be close and I have a sub so it is not as important. I am asking about the treble and mid range sound.

Big difference or slight? Worth the extra approximately $100?

M22s, QS4s, M2 center, Hsu stf-1.
