You are probably correct that you can't tell the difference but I'm looking at it strictly from a comparison standpoint. If the 2809 is 115W at .08%, that means it's actual lower when rated at .05%. It's probably somewhere closer to 100W @ .05%. The 2808 was rated 110W @ .05%. So hell yes this matters to me, especially for this kind of money in a receiver.
You're basically paying for a few extra features but losing power for an extra $200-$300 then.
Onkyo is pulling the same thing w/ the 805 to 806. Both rated at 130 watts but went from .05% in 805, to .08% in 806, which is just a numbers game and actually means the 806 actually has less power if you compare them both with the .05% numbers.
lol, 100, 110, 90, 120 and so on...do you know the true audible difference in this different Watts/ch ratings?
Its only a 3 dB difference between 64 and 128 Watts so 90 to 120 is not even audible.
you are splitting hairs and also do you realize that in a true third party tests seldom to the documented specs match the test
People have to get over the whole Watts issue because it is simply meaningless. If you care about Watts buy and 250W/ch amp that truely has better Dynamic range, better THD.
I personally would never use an AVR amp, I always use my AVRs simply as pre/pros because the amps in them are not good enough for me and my system.
