Rich, i have read your thread, and i am going to agree with JohnK.....
I am a firm believer of separates and fully agree with your analysis of the benefits of having separates, however in your case i do not think you will notice much of a benefit. I am also a firm believer in value purchases. Since you have the M3's the lowest impedance that your amp will see is just below 8ohm's, according to the current impedance graph. If there was a range that the M3's would drop to say 4ohm's or 2 ohm's then i would say to go for it. However with the above data, i can not agree with your desire to buy a separate amp. if you had some M60's or M80's then there would be no question, i would be telling you to buy the best amp your budget can afford. However in this case, JohnK is very correct, you will be paying for head room that you will likely never use.
Good luck with your decision.
