(ask ccotenj). Where you do prefer Audyssey over YPAO, in my man cave the Yamaha and YPAO do indeed make the Onkyo sound lacking something for music. The Yamaha sounds very good. The Onkyos are good to me,just not really good. I miss the reliability,the build quality, and the solid feel of the Yamaha's. Something that the 876 lacks. I also do not believe that this 876 will have the lifespan of my 2600. There is just something lacking with the 876 I can't put a handle on. Good luck with yours, whatever you decide to do.
Actually I think the THX Ultra certification has a lot to do with the reason I like the Onkyo....the 2600 was THX ultra or THX select certified?
There is a big difference
Not that its a guarantee of good sound...but just a guarantee of sufficient power
Here is an except from Sound and Vision from about 4 years ago remarking on the 875's power...I am certain this is applicable to the 876 as well as I am certain their use the same amp and power supply section"I got stellar bench results from the TX-SR875. Noise and distortion were state-of-the-art, and frequency response was excellent -- though with an inconsequential rolloff of about 0.5 dB per octave above 10 kHz in all modes. Power results handily exceeded the receiver's ratings in all except 7-channel-simultaneous testing, which came very close (128 wpc). Bridged output measured in excess of 300 watts x 2 into 8 ohms. The receiver got quite hot during prolonged power testing, and the fan (which came on only under severe stress) was a bit noisy -- though with a program playing, users should never hear it."
Here are the bench tests of the 3900 by the same magazine
1 channel driven: 189/270 W (22.8/24.3 dBW)
5 channels driven (8 ohms): 100 W (20 dBW)
7 channels driven (8 ohms): 88 W (19.4 dBW)
Neither the Z7 or the 4310 meets its stated power ratings with 5 channels driven. I think explains some of my findings with my ears.
I put several receivers through the paces in the past 30 days...all with a set of Vienna acoustics speakers,,,which are 4ohn and very hard to drive
I picked them specifically to use as test subjects because anything that could drive them had to have some "muscle"
The used a mix of a mix of digital music from Pandora...some tracks from the Joe Sample CD..Samples This...and some scenes from the Blu ray movie Avatar( DTS-MA)
The receivers:..Denon 4310...sounds good and very technie...but runs out of gas at refernce levels of volume
yamaha Z7...a little better than the Denon..but still not enough real world "muscle".....sounded harsh and strained at louder levels
Onkyo 875..much better than than the Denon or Yamaha..never felt the receiver was out of "gas"...a lot more dynamic than the other two in the highs and lows
Curiosly the Onkyo weighs about 11-15lbs more than the Denon or Yamaha
Then for grins yesterday
I pulled out and old Pioneer elite VSX47TX...a 67# beast that I bought on ebay a couple of years ago for $225...I think retail was $3K when it was current in 2002-2003
I could not use DTS-MA on Avatar...but I have to say other than that it would be the clear winner of all the receivers...way more dynamic ...I played this at ridiculous volumes for a long while and it made the Viennas sound fuller and image better than the other three...easily
getting back to your situation
I can't say the build quality is bad on any of these...again..if I were to give a winner I would say its the old Pioneer elite that is the best built...there is copper plating all over the thing
On another note I have an Pioneer Sc07 as well...and the old VSX47 beats its hand down in build quality
In regard to the 876...and I understand it sounds just like the 875 except with better video processing
There is a huge weight difference in the 876 and the 2600..right?
I am not sure what you mean by solid feel
What's the weight difference in the 876 and the 2600
There is definitely a big difference with the z7 and the 875..if I were a betting man I would say that extra weight was amp section and power supply...which is likely the reason I prefer it
I like Audessey...and I like Pioneer's MCACC....Yamaha's room correction is the least tweak able...from my experience
though thats not a deal breaker and good sound beats room correction software any day of the week
as for reliability..I can't speak to that
I have had issues with the Onkyo...but the Z7 I bought was a floor display and it has issues as well right out of the gate
Ironically..it was the same issue for both the Onkyo and the Yamaha...the HDMI PC boards needed replacement...an expensive proposition if you had to do it on your own dime
