I don't have direct experience with the XR50, but rather with its predecessor, the XR25. I would be concerned about brightness with that combo. 2 suggestions (in order of likely effectiveness):
1. Modify the Ed Frias speakers using the GR Research crossover to solve the brightness issue. Details are available either at Speaker City or GR Research.
2. Go with the JVC RX-F10 instead of the XR50.
I would more strongly recommend the first option, since it deals directly with the problem. The second option simply makes the problem more tolerable (but it involves less effort/$).
