Rega products are said to be nice, although I have no direct experience. The Rotel integrated amps do have a phono stage, which was another nice plus over NAD for me. I don't know about those Usher speakers (a dealer I visited did have a pair of Usher something-or-others hooked up to an Integra for demo purposes, but that's my sole experience with Ushers), but the 60 W Rotel RA-1520 was driving a pair of B&Ws in the dealer's, and B&W speakers are generally known for being wattage-happy. The dealer I bought from also said that the Rotel (also a similarly-spec'd NAD) should have no problem driving my very inefficient Smaller Advents. (I haven't hooked it up yet to test because my Advents are still in the shop.) So I don't think you Ushers should be an issue.
