I have a mission SXC2 Centre, Audica CX Towers as fronts, Monitor Audio Silver as side's and Jamo 626 Towers as rears and a Jamo Sub. I know its a mixed up lot, but have to have them like that for my marriage! I also use decent quality speaker cable too, all with banana plugs.
I have actually pushed the button and ordered the MRX 510, so hopefully I will be able to post whether or not I hear any major improvements! I am getting a tech to do the install, so hopefully he can get the best out of my speakers that maybe I cannot with the Audyssey!
Thanks for the response.
