Just finishing my second week with the 607, and with one exception, I am very pleased. It replaces an Outlaw 1050, which was and is a terrific receiver, but no HDMI, no recent audio codecs, etc. Running the 607 with a 50" Panasonic plasma, Panasonic Blu Ray and Toshiba HD-DVD players--sound and video are great. (Paradigm surrounds, vintage AR main speakers, Panasonic sub and center) Audessy set up went smoothly, and I haven't felt any need to fiddle with those values.
One issue--more of a question--the heat. After its been cranking for a couple of hours, its almost (but not quite) too hot to rest my palm on the top of the unit. I know HT equipment runs hot--but this hot? A little hard to believe that anything running with this much heat will last 4 or 5 or more years--but I hope so. I'm not going to return or exchange it--I like it far too much--but would appreciate anyone else's thoughts or reactions to the heat issue. It's on an open shelf, with about 12" of clearance above, so the heat is dispersing--but even so...
By the way, I have added a UP-A1 iPod dock--a very nice accessory, which sounds terrific, and which works on both video and audio. (But--you guessed it--since the thing charges the iPod, it draws some juice even when the 607 is turned off--so it seems to stay a little warm, even then.)
Thanks--enjoy your 607's! Cheers from South Jersey.
