I have e-mailed customer support at Harman Kardon and have gotten extremely vauge answers concerning the release of the AVR 7550HD. They used to be a cutting edge company but in the last few years they have yet to release a product in a given model year that seems better than the competition. I recommended their products to friends and family members loving the sound of my AVR-525, and all of them are on 2nd or 3rd receivers because of glitches, firmware issues, hdmi incompatability, 2 or 3 of the 7.1 channels just not working, inability to detect and select the right sound mode(ie. dolby ex when a digital source is fed in). They honored the warranty but they all had hassels returning and getting replacements. I think it's sad. I hung onto my AVR-525, after christmas I couldn't wait any longer for HDMI, TrueHD, MasterAudio, and some of the modern features like ipod connectivity. I ended up buying a Pioneer Elite VSX-94TXH. This model is great for movies, but I miss logic 7 for music, I miss the warmth and power of the Harman amps. I hope for Harman Kardon's sake they release a flagship model AVR 7550HD or other comparable model this year. Even loyal H/K fans won't wait forever. Just my 2 cents on this whole thing.
