Are those measurments "output at clipping" as usually with S&V


Those measurements are beyond clipping (1%THD). The receiver probably starts clipping at something like 0.05% THD. So discount 10-15 watts/ch to get to the clipping point.



The truth is not out there but within you.

Here is a little more info from the "in the lab table".

Reviewer: David Ranada

DOLBY DIGITAL PERFORMANCE

Output at clipping (1kHz, 8ohms)

1 ch driven..................151 W (21.75 dBW)
2 ch driven....................139 W (21.5 dBW)
5 ch driven.......................107 W (20 dBW)
7 ch driven....................93 W (19.75 dBW)

Distortion at 1 watt

(THD+N, 1kHz, 8 ohms).....................0.028%

Noise level (A-wtd, 16-bit signal)....-75.9 db

Excess noise (with sine tone)

16-bit (EN16).....................................0 db


Frequency response

20 Hz to 20 kHz+0, -0.26 db


"Denon's AVR-3805 did unusually well on the test bench. While the power figures were very good- and adequate for all but the very largest rooms."

You Canadians think you're getting shafted by the price? Here in Oz the RRP of the 3805 is $2499 which is surprisingly down from the RRP of the 3803 which was $2699.

Considering the Oz dollar is worth 70 US cents in theory the 3805 should only be worth roughly half what we have to pay.

We have big taxes on luxury items down here so you guys in Canada might just not be being treated as harshly as you think.

This should be true of any receiver that you connect similarly.
i don't know about the 3805, but there are a few receivers that will allow bass and time management of the external inputs.

"Denon's AVR-3805 did unusually well on the test bench. While the power figures were very good- and adequate for all but the very largest rooms."


--------------------------------------------------------------------------------


That is exceptional performance for this class range.

Denon exceeding their own ratings being they rated it 120 watts/channel with "2" channels driven, NOT 5 CHANNELS DRIVEN. There's only a few receiver makers that rate with all channels driven, HK and NAD are two. Most others rate wattage figures for all channels but when only "2" are driven. Denon, Onkyo, and Yamaha are 3 that rate this way. So by no means did Denon not meet it's ratings, but it EXCEEDED it's ratings.

S&V rates at .3% THD as seen in their test explanations posted by a member in this thread. It's not nearly 1%. Stereophiles Guide to HT, HT magazine and S&V all rate power at 1Khz so full rated bandwidth ratings are a pipe dream unless you go with a questionable online or foreign review test.

Regardless, even these 3 magazines seem to oppose the other when reviewing the exact same receivers. I've seen this over the years where the differences were only about 10-20 watts. Presently the differences jumped to 50 or more watts so going by tests is not an end all in finding the real output. Even though they all rate near the same specs., there can be variables in their physical testing methods which cause the large differences. Until the power tests are regulated by an impartial agency, nothing is comparable.

To be honest, since S&V rated the 2803 very well on power, along with the AVR-3805's predecessor, the AVR-3801, I'm not really surprised that the AVR-3805 rated so exceptional for it's price class. Being that the only differences between the AVR-3805 and AVR-3803 seems to be preamp features, this also puts the AVR-3803 in a good lights from the S&V power test.

Not many receivers in this $1000 - $1200 price class have came close to the 107 watts/channel with all "5" channels driven in recent S&V Reviews.

Have a good one.
