They are getting a lot of work and I'm loving every minute with them. The Revel/Parasound combo is a good match. I use the F52's for two channel backed up by the dual Fathom F113's and my system has reached a new level and never sounded better. I have been watching the Band of Brothers DVD set and the 5 channel sound is just unbelievable. I wish I could work those M22's in somehow.
I have been working on the Pre-Pro side of the system to get rid of my amp/speaker switching. Adding another pre/pro did the trick. I am now fully automated in my speaker switching. If you are going to be in the area give me a call and come by and check it out.
