15-series AV components, but we're glad to see that a thorough review of the 5.1-channel RSX-1550 receiver has gone up at AVGuide. As a marque that sits at the high end of the spectrum, some quirks are to be expected, but Rotel has finally gotten onboard with HDMI 1.3 connectivity, Dolby TrueHD and DTS-HD MA, and independent subwoofer crossover frequencies for each channel. Also, it sounds like Rotel changed the "house sound" slightly, with a shift towards a more "gutsy" sound with a bassier presentation. Overall, it sounds like the RSX-1550 turned in a solid performance, but outside of Rotel's loyal following, $2,000 for a 5x75-Watt (conservatively rated, but still) receiver that forgoes auto calibration is going to be a tough sell. Audiophiles who complain about feature creep at the expense of quality, however, should take a look -- the RSX-1550 looks like it bucks the trend.
