Hi ALL,

I am looking at two AVRs. I currently have a Denon 790 and it sates the power is 90W per channel for each channel seperately.

I was looking to upgrade to an Onkyo tx-nr709 and it says the power is 110w per channel 2 channlers driven?

Can that be right? Can the Denon 790 really drive each channel at 90 with the same distortion level the Onkyo 709 can only drive 2 channels at 110? Here are the specs..

ONKYO


Power Output
Front L/R

110 W + 110 W (8 ohms, 20 Hz-20 kHz,
0.08%, 2 channels driven, FTC)
130 W + 130 W (6 ohms, 1 kHz, 0.1%,
2 channels driven, FTC)

Center

110 W (8 ohms, 20 Hz-20 kHz,
0.08%, 2 channels driven, FTC)
130 W (6 ohms, 1 kHz, 0.1%,
2 channels driven, FTC)

Surround L/R

110 W + 110 W (8 ohms, 20 Hz-20 kHz,
0.08%, 2 channels driven, FTC)
130 W + 130 W (6 ohms, 1 kHz, 0.1%,
2 channels driven, FTC)

Surround Back L/R

110 W + 110 W (8 ohms, 20 Hz-20 kHz,
0.08%, 2 channels driven, FTC)
130 W + 130 W (6 ohms, 1 kHz, 0.1%,
2 channels driven, FTC)


Or is the Denon really also 2 channels driven like the Onkyo?

Denon AVRs are generally rated into 2CH as well, as are most AVR brands, although regardless the difference of 20W/CH would be moot. The 709 is more in line with the 2312CI, and both use Audyssey MultEQ XT which would be an upgrade over the MultEQ used on the 790.

Jd, thanks for the input.

How come the website and manual for Denon says that all channels are rated then? I am confused.

Surely I would rather keep my Denon if its 90w x all channels vs 110 x 2 on the Onkyo.

I highly doubt you could tell a power difference between those two receivers....

What a mfr uses as it's "marketing" rating and the actual benchmark testing values is very different. The 709 is a more powerful AVR than is the 790.
