Summary: Here it is in 2011 and the process to configure this unit (Marantz NR1601 Audio Video Receiver) is something out of the 80's. I know I can't expect an iPad on the screen, but the on-screen setup is painful. You get options, but no explanation of what the options mean (i.e. "Select Small or Large Speaker" What does that mean? Hint: It does not refer to physical size!) And the manual is fine if you designed the unit, but impossible otherwise.
Summary: Great sound, small form factor. Of course, the sound will depend on your speakers. I have small Cambridge Soundworks Ensemble 2 which come with a subwoofer and a center B&W and two small bookshelf B&W speakers. The only downside to this receiver is the manual that comes with it. Does not appear to have been written very well so it means you'll be doing a fair bit of guessing to fill in blanks and get the receiver to do all that it can.
Summary: Bought this open box and I absolutely love it. The sound is fantastic and has a much smaller height than the typical receiver. Major surround settings and supports a ton of different setup options. Setup was easy and drive my canton small home theater speakers with ease. Had some difficulties with sony 3d bluray and PS3. Had really bad flickering.
Summary: So finally this thing was released earlier this month. And by the gods, it does exactly what I had hoped it would do -- allow me to pair an optical input with an HDMI source. I can now run one of my computers seamlessly to my 62" DLP with full SPDIF audio! All thanks to this little guy. I haven't toyed very much with it yet, but I intend to expand this review as I do so.
