If I were you, I would get the M22Ti's over the M3's if you are only listening to music. You might want to fiddle with your amps settings as well, if there is the choice of setting them as Large or Small speakers. Large will give you more bass.

I have heard the Cambridge 500 stereo amp, my father is thinking of buying it. I thought it was incredible. I heard it with JMlab chorus 706 (550$ CAD retail) and it was an excellent sound. The M22's are likely better speakers, so it would probably just sound better.

good luck deciding! but, just to re-iterate, get the M22's, Factory Outlet if needed.
