Those Motions are 4 ohm speakers. I'd suggest a little more receiver (or separate amp) and a little less OPPO. Ac4l.com has good prices on refurbished receivers. Look at the 705 or Denon 3312/3313 which are very similar to the Marantz on the inside. They also have the Marantz 7006 and 7007 Bluray players. Not quite an OPPO 105 but pretty good none the less.
Or the Denon DBT 4010. 125 db s/n ratio.
I know the Marantz 6007 isn't rated at 4 ohm, but I would assume it could handle those speakers, no? I've read both the concern -- often about the heat -- and rebuttals of said concern elsewhere, but I don't know who to believe. Are there any particular drawbacks that concern you there?
I am also worried about the versatility and the quality of sound of alternatives to my Marantz/Oppo combo. Perhaps the salesmen just did a good job on me, but I like the Oppo's combination of the versatility, the quality DAC, and the polish of the unit. I will be listening to music in multiple formats and watching video, and want something that can handle all the digital and disc-based media I can throw at, and want to use something that will maximize the quality of that media. I'll be hooking a Sonos Connect and an HTPC (well, really, just my PC with a large cache of digital media stored on it) up and will run it through the DAC, will run my cable box through the unit via the HDMI in, and will use both the RCA outs to the AVR with the 5.1 setup and the HDMI outs (possibly direct to the TV for video). I also like the Roku stick compatibility. My worry is that I am unsure I can get the same benefits in more discrete/separate packaging for the same price (which is also the reason I opted for an AVR rather than separates). However, I am very open to change, as I am a novice here, and I worry that I'm not making the most efficient use of the money.
