Summary: The 2nd zone only take analog sources so it is pretty useless, I have everything hooked up using optical audio for the first zone so for the second zone I can only listen to radio and the ipod bridge doc.
Summary: The AVR is user friendy but mine will not output resolution higher than 480P. I was told by HK that if all your inputs and output are not the same cable you cannot output full resolution. So if you have one HDMI input and one Component or DVI input all you will get is 480P output. My opinion ...waste of money.
Summary: this was my third harmon receiver, but my first with HDMI switching. The video upconverting is questionable. 1080 seems to flow thru without to much change, anything less 720,480 looks WORSE then before. I think mabey it should be called downconverting instead. And when playing games on my playstation 3 the screen will just up and go blank for about 30 seconds then come back on. This will happens every hour or so, LAME.
Summary: The HK AVR 354 has a ton of bugs, the new firmware update helps, but doesn't solve all. First the USB to Serial cable from radio shack ( gigawire) works really well. Don't try any others, save yourself some time and just run to RadioShack and get theirs. Make sure you do the firmware update first because one of the PROBLEMS is an intermittent POP that is sometimes intense and BLEW one of my tweeters on my rear left surround.
