I am interested in the epic grand master 500 set up and am wondering how much I am losing going to the m22 speakers over the m60. My girlfriend is keen on having the speakers on the wall and I am having a tough time convincing her otherwise. Is there a large difference in sound quality between the 2 sets? Will I be disapointed that I didnt get the m60? I guess thats a pretty subjective question but any thoughts will help. thanks for any feedback
