Long time lurker with this thread - just wanted to add my impressions with my 3 days so far with the 875.
I am coming from an Outlaw 950 with 2 channel B&K 4420 for fronts and an older Rotel 976 running the remaining 5 channels. Speakers are older Energy e:XL series - "26" fronts, "C" center, "16" side surrounds, and "R" dipole back surrounds. They are all 8 ohm. Sub is a SVS 20-39 PCi. TV is Sony 60" RP LCD KDF-E60A20 (768p native) .
I was looking to accomplish a few things with this purchase - (or "how I convinced myself to buy this thing")
My usage is about 99% home theater and gaming - 4 years ago it used to be about 60% home theater / 40% music. Kids will do that to you. So, I felt I could "get away" with coming off seperates.
Current TV has only 1 HDMI input and I have 3 (soon to be 4) HDMI capable sources. So, looking to run them all via HDMI. Also, looking to ease switching between components (for the wife of course!).
Wanted to be able to listen to uncompressed audio on HD-DVD / Blu ray.
Finally, My TV falls in the Sony line that fails to properly deinterlace 1080i content. The E55A20 failed which is essentially the same TV as mine - just 5" less in screen size. See http://www.hometheatermag.com/hookmeup/0506halfrez/
So, I liked the idea of the Reon being able to properly handle 1080i - plus it could upscale SD content very well.
I did think of going with the Integra 9.8 pre/pro and keep my current amps but (1) local dealers pricing for it was $250-$300 more than what I could get 875 for and I'm already slightly over budget (don't tell the wife.) So, now I could sell my old amps to get under my budget hopefully.
My sources consist of DirecTV H-20, Toshiba HD-A2, PS3, XBOX 360 and Wii. Spent most of my time so far with HD sources so been mainly dealing with the DirecTV box, Toshiba HD-DVD player and the PS3 for Blu Ray - all with latest firmware.
Initial impressions were that this thing is a tank and I prayed my A/V rack would hold up to the weight (it has so far). Fit and finish are superb and it looks (if that matters to you) very nice - especially with the front door. Once I had everything hooked up I ran the Audessey setup. I was very disappointed with the results. Very thin sounding and there was no bass. I tried to run it again with the same results. It even made some odd desicions on my setup - it set ALL my speakers to Full Range! - even though only the fronts are floorstanding. The distances were pretty good and the EQ was just awful. I proceeded to turn EQ off and pull out the trusty Radio Shack SPL meter and 5 minutes later everything was much, much better. I may try and run Audessey again if I get really bored but I doubt it. I was really hoping it would have been better. I thought I did everything right - even using a tripod for the microphone - just wasn't for me.
The menu system is nice - easy to ready and follow after a few times through. It did take me a while to setup the default listening modes though as I didn't realize that the HDMI settings were "hidden" below the analog defaults for each input. Reading the manual solved that.
I've had NO HDMI handshaking issues. The video takes about 2-3 seconds to display when changing inputs. There are some minor clicks from the reciever when changing inputs - but nothing that seems abnormal.
Haven't had any speaker "popping" issues with normal use. The PS3 seems to make some minor noises - but no loud popping. I had similar issues with the Outlaw and the PS3 and I beileve this is a know issue with the PS3. Only time I had any real "popping" was when entering the setup menu from certain spots when the volume was too high. I've since learned to turn the volume down before entering setup. Didn't happen all the time but happened twice to me. Overall I have no concerns here - under normal use everything seems fine.
Sound quality seems to be very transparent and clean. My prior setup seemed to have more warmth but less detail than I hear now. Going through various demo discs that I am used to I am very happy with the overall sound quality.
I was a bit dissapointed with my first True-HD experience. I guess I was expecting more of what I experienced when I heard SACD and DVD-Audio. I guess with dialogue and explosions it is hard to tell a big difference. Glad to know I am getting the uncompressed sound but DD+ was/is great sounding.
What impressed me the most was the magic the Reon performs on the video signal. I can really see the difference. HD just seems clearer, sharper and more detailed. I haven't seen enough SD to make a call on that - mainly only DirecTV SD channels and with that - as they say - crap in, crap out. I do have to see how some SD DVD's look. It does a superb job feeding my TV an excellent 720p signal - couldn't be happier (unless they add the 905 Reon settings)!
The unit does run very hot and there is even a sticker on top warning of this! Thankfully my unit is not enclosed and can breathe freely but I would be concerned with this unit in an enclosed space.
