Well I've had my 3007 for almost 3 weeks now. Thought I'd leave a little review here, remember just my opinion, not trying to upset anyone

.
For a little background I have the new 600 series B&W speakers hooked up to a B&K AVR 505 receiver which pushes out 150 watts per channel 8 ohms all channels driven. It is a beast and I love the sound but of course miss the HDMI capabilities. I use an Arcam DV137 as a music source and an Oppo for DVD and a PS3 for bluray. My listening is prob 60 percent music and 40 percent movies.
That being said I was impressed with the build quality of the Onkyo. Almost weighed as much as my B&K, but I should note the B&K is only a five channel receiver vs. the nine channel Onkyo.
Hooking up the Onkyo to my 1080p Samsung, I had no picture issues or dropouts. I set my Oppo to 480i and allowed the Onkyo to scale to 1080p via HDMI. Killer picture, I feel that the video processing in the Onkyo bested the scaling in the 983. Just seemed to be sharper and more colorful than what the Oppo does. Blurays looked great, actually everything did when run through the Onkyo including my HD satellite box.
Movie soundtracks were very good. Not fantastic, but very good. So many different selections to choose from for sound modes, it was fun to flip through all of them. It is amazing how good the lossless codecs sounded, streamed to the Onkyo via HDMI from the PS3 in multi channel PCM.
Then I decided to try music listening. This is where the Onkyo came up short in my opinion. 2 channel listening just did not sound right. The midrange was detailed, but the bass was lacking and the highs just sounded like something was missing. Very flat. I tried with analog outs from my Arcam, I tried digital in from my Oppo, I tried with Audyssey engaged and disengaged. It didn't matter, the music seemed lifeless. I had been so excited to see the high quality phono jacks for both the CD and the turntable input, but they didn't seem to help the sound any. Streaming SACD and DVD Audio via HDMI didn't sound as good as I hoped either, though it was of course much better than the stereo sound of the CD input.
Speaking of the turntable input, man why do they even bother putting these cheap things in? The phono preamp is definitely a cheapy, I found that compared to my budget Cambridge Audio preamp it wasn't even close to the same league.
I pulled the Onkyo out tonight and put the B&K back in hooked everything up and was back in audio nirvanna again. Sure I don't have all the latest and greatest bells and whistles, but I do have that quality two channel sound and I guess I'll just have to put up with that until one of these higher end receivers with HDMI comes down in price. So the Onkyo will be returned tomorrow, if I was to keep it I would have to purchase a stereo preamp with HT bypass and a separate amp to go with it.
Pros:
Great video processing
Good detailed midrange
Great connectivity
Audyssey
Cons:
Music listening, especially stereo is lacking in bass and treble
Disappointing phono preamp
