The Onkyo TX-SR875 is a high-end 7.1 channel audio/video receiver as part of Onkyo's latest lineup of products supporting HDMI 1.3a. Along with the flagship Onkyo TX-NR905, the TX-SR875 are the first receivers to include Silicon Optix's acclaimed Reon-VX HQV video processing chip that effectively up-rezzes all video sources to 1080p. The receiver features 4 HDMI inputs, and 1 HDMI output delivering 1080p signals with audio.

From the audio and amplification standpoint, the TX-SR875 features a dual push-pull amplifier configuration, with a three-stage inverted Darlington circuit. It also includes top-of-the-line Burr-Brown DACs for high efficiency and high current with low distortion. It also supports bi-amplification (with compatible speakers), and bridged operation for a high power setup. In normal operation, this receiver can deliver 140 W to each of its 7 channels.

Features
  • Full A/V Processing via HDMI 1.3a with Upconversion (4 in 1 out)
  • HDMI Deep Color Capable (36bit)
  • Component Video Upconversion and HDTV-Capable (100 MHZ) Video Switching (3 in 1 out)

Only thing I'm looking for is speaker to go with this receiver.

Also, in fairness, the HDMI handshaking problems mentioned above can occur with many brands and are hard to predict, hard to troubleshoot, frequently difficult to reproduce and sometimes seem to have something of an alchemic quality to them. It's very hard to logically lay the blame at the feet one component when it could be the source or display or the particular combination of all three.

Also, in response to Post 5 ('I don't think it even tries to upconvert or smooth out the HDMI in from my 1080i cable box. very blocky. I hate that.')

The reason you are getting pixelation from your cable box is most likely because of the level of compression being used by your cable company. Remember that not all HD is the same regardless of how it is labeled. The level of compression will vary from one provider to the next and even from one channel to the next even though both are from the same provider. This is almost absolutely not the fault of the receiver. It will, if properly configured, transcode any video source from analog to digital and upconvert up to 1080p. But if the source in question is basically garbage (i.e. Nintendo NES, over-compressed HD cable, VHS) then you are getting upconverted garbage that probably looks better than it would have without the processing, but still not to the level of a 360, PS3, or a quality Blu-ray or HD-DVD transfer being played from a quality source.

In response to Post 16: It will do the upscaling, and the Standard-def sources will look somewhat better, but you won't be able to gild a turd with this thing. It doesn't work that way - especially with something like the NES, which was never really even a quality 480i source to begin with. PS2 will look substantially better because the source material is better than NES.

As for which processor will do better, Home Theater Magazine just did a review of the video processing of a bunch of AVR's. The only receiver whose video processing came close to that of the Denon AVR-5308 ($5200 list) was the Onkyo TX-SR875 (the TX-NR905 uses the same processing and should perform the same while adding a bunch of convenience features). The reason for this is that both use processors from Silicon Optix. Presently, no other video processor available in a mainstream receiver come close to the performance of the Realta and Reon processors.

I have a quick question about this AVR:

How will it upscale old composite signals of video games (like the Nintendo NES) and component signal of lets say the Playstation 2.

Will there be a delay between me pushing a button and seeing action on the screen? how well will it work -- if anyone knows please let us all know.

My primary reason for looking into upscaling AVRs is to have my older video game consoles run and look well on my 37" 1080p JVC LT-37X688. Which video Processor will do the best job at this? Reon-HQV or Faroujda? (or a third party)

Thank You.

I recently upgraded my system as a whole, to include the 875. Presently, the system as it is being used is a 360 w/ HD DVD as a source, the 875, a Westinghouse 42" 1080p LCD flat panel, and a Polk Lsi speakr package with LSi-25's up front, and LCi-C center channel and LSi-15's as rear channels. Initially I had been running the 360 directly to the TV while I was sitting on the fence about what kind of receiver/speaker package to buy. I can tell you that running the 360 through the receiver then on to the TV actually IMPROVED the picture, for both HD-DVD and DVD. In the next day or so, I will be getting an Onkyo DV-S504 universal DVD player for playing standard DVD, SACD, and DVD-audio, as playing standard DVD over the 360 is a generally disappointing experience due to its poor upconversion of DVD's 480i/p resolution to 1080P.

I will also add that, although in the $1600 price range, there's certainly a fairly level playing field if you are looking at a Denon, Pioneer Elite, Sony ES or Yamaha, vs the Onkyo, there are a number of factors which decided me in favor of the Onkyo.
1. Better remote control than Pioneer, Sony or Yamaha
2. Better video processing than Denon, Pioneer, or Sony
3. Sound quality that I preferred to all of the above, but especially the Yamaha.
4. Simpler onscreen display controls than all of the above

Overall, I am exceedingly pleased with the package I have set up and I can tell you that the sound of the Onkyo/Polk system is absolutely awesome. Even playing MP3's (disclosure: I only have high-bitrate MP3's) sounds great assuming you let the Onkyo do the DA conversion.

Tips: you can access the Reon menu by holding the DISPLAY button on the remote for 5 seconds. Display wion the receiver only.

To check firmware version, on the receiver (not remote) hold DISPLAY button then press STANDBY.

Full tweking of the Reon HQV is now available with the latest firmware v 1.04 which is now shipped as standard for the 875. For the 905, the same firmware is given version number 1.05 but they both addressed the same issues.

Owners in the AVS Forum thread talking about the handshaking problem [link]. It sounds as if there is a handshaking problem with the DirecTV HD-DVR (HR20-700) that apparently can be fixed by powering up a PS3. Weird.

In the Pros and Cons section, a note was made above with "Problems with HDMI handshaking with some video sources" with several agreeing.
Can anyone comment on these issues?
