Not sure if you have already made your purchase or not, but I have owned my pair of M30's for a year now, and have never grown out of them. They are so accurate at reproducing sound that they are a joy to listen to, and without the slightest hint of fatigue means I can listen for hours at a time. I have REL sub hooked up to bring the frequency response a bit deeper, so keep this in mind. Any speaker of this cabinet size will likely benefit from using a sub with them.
Cheers and best of luck.
