2 channels driven gives you a pretty good idea of amp performance, all channels driven is dependent on protection circuitry.
The 805/875s did not have this protection circuitry and this is what led to so much overheating/failures. The 5xxx Onkyo series use the same amps today, but with larger output capacitors (44,00uf vs 30,000uf). Look at the numbers now:TX-NR5008 measurements (55lbs)
Five channels driven continuously into 8-ohm loads:
0.1% distortion at 79.1 watts
Seven channels driven continuously into 8-ohm loads:
0.1% distortion at 78.7 watts
Now look at:TX-NR807
: 30W x7Denon 4810
: 30W x7
Receivers made in the last 3 years all have aggressive protection circuits to prevent people from running party mode (stereo x7) at max volume and blowing up their precious $2000 receiver. For home theater, you only need power in sporadic bursts, and the Yamaha RX-A3000 will give you 150W x 7 according to Audioholics
. 2CH performance will give you a good idea of what it's real abilities are.
Yes the RX-A3000 isn't as powerful as the Z11...but the Z11 also has obnoxiously loud fans, like all the 70lb fossils of yore.
The denon 5308 would be the clear exception to the "generation"
as for the receivers you mentioned..as for flagships..its not what it used to be
and the far lower prices and "made in Malaysia " labels reflect that
what overheating issues/failures are you talking about with the 805/875?
That really can't be substantiated..because the newer Onkyo's with less power seem to be on par with the same reliability.....look at the xx07 threads
...the Z11 is a fossil?..thats interesting if all HDMI 1.3 are now considered fossils?
The Z11 has some serious performance....obnoxious loud fans?
Seriously..all one has to do ..if they want 3D capability is to buy one of the several Blu ray players with dual HDMI outputs
I have a flagship Pioneer VSX47TX( 63#) from circa 2003...its fans are minimal and its build quality better than anything else..receiver wise..I currently own
I do enjoy its musicality, weight and all the copper plating
it handles some 4ohn speakers I have much better than any other receiver I have owned
For reference..I have the Yamaha A3000..Pioneer Sc37 and Onkyo 5009 in my home currently
..as far as what one "needs"...I am not sure anyone needs a Yamaha A3000...if that is your litmus test
There are lot less expensive options out there that will fulfill the same functions
Its frankly more what one wants
the Denon 5308 is the only flagship receiver that remains in today's world...in the mass produced sector
if offers performance that is on par with some separate amps...though you do have to buy the upgrade to get HDMI 1.4 and the latest version of Audessey..XT32
If you think the performance of those receivers are fossils...then I assume you clearly dont think the performance of separate amp/preamp combos is acceptable?
I say that because the only way you can get that today...is separates
