Denon 3805 running Auto EQ when bi-amping

I probably have way too many variables for anyone to be able to assist me with my question but here goes.
I have been using the Auto EQ quite a bit with an (Audioholics method) 3805 bi-amped to my main speakers. It seemed to work well even though in the 3805 review Clint indicated it was better to do EQ manually. I just upgraded my main speakers and ran Auto EQ again (for about the 100th time). I'll admit there is a very good possibility that the EQ is not optimized, but I have so many issues with my setup regarding the room itself and the speaker position that I do not have a baseline from which to compare. It sounds good to me, but so did my Bose LS 12 system until I started this quest for AV nirvana. I should probably call in a pro but I'm determined to do this OMO. Other than rambling, I guess my question is has any other bi-amped 3805 owner (there must be at least one other fool) used Auto EQ?... Seem to work OK? Does the Biamping effect the Auto EQ or will it auto adjust to the slightly increased bass levels I have set with the 3805 Zone 3 amp?

Unfortunately I have no information for you however I'm also a new AVR-3805 Owner and I've been thinking about trying the "Bi-Amp" route with my mains. How did it work for you ? any noticeable benefits ?

Truth is I don't know what the hell I'm doing. I followed the instructions from the 3805 review and I suppose there is a benefit. As I said, if I had more of a base line with this equipment I'm sure that I would have more definite feelings about the results. Most "knowledgeable" audiophiles will tell you it is a waste of wire. I found more bass/treble control and theoretically more watts output to my speakers. It only cost some speaker wire and a little time so what the heck. I'm in the market for a good Power Amp to drive my fronts so what does that tell you :rolleyes: .

I have mine bi-amped and like hidog1 didn't notice a huge difference. But it didn't sound any worse so I left them bi-amped. Some have complained about a hum from the speakers when bi-amped but neither hidog1 or myself have this issue. It must be the atmospheric electrons in the Sacramento area. :rolleyes: I say give it a shot and see if you like it. Go to Home Depot and buy some 12 or 14 gauge speaker wire, it will cost you maybe $10 to experiment.

Biamping the 3805 completely ruined the sound for me. There was hum. Everyone has the hum or you have not set it up properly. It is annoying. It also creates a tonal imbalance. This is "ghetto biamping" and I recommend getting a power amp. i have a NAD 2200 on the lows only of my towers. It unfortunately does not have a gain control so I can't turn it up at all but I do notice a difference one I push the power button on th amp.

Trust me. Biamping adds a little bit of bass but to hear it you have to turn zone 2 up and the more you turn it up, the more hum you get. It even effects all the other surround speakers.

All you need to know is Denon did not make the Zone 2 or Zone 3 amps the same quality as the main zone or this receiver would have cost thousands. So why use a weaker quality amp from the other zones to degrade your main zone. Like I said, tonal imbalance.

No hum here, maybe I got the humless version of the 3805 or like Duffinator speculates "it's in the air", or maybe it's because I wear one of those tin foil beenies (like in Signs). Seriously Johnny Canada, what your saying doesnt make a lot of sense... but hey, I'm the guy who admitted I don't know what the hell Im doing.

I'd be interested to see the specs on the 3805 Zone 2&3 amps. Are these available or are you speculating based uponthe price? I think it would be foolish for Denon to put two grades of amp in the same box and create a "tonal imbalance" My 3805 (unbalanced as it is) sounds pretty darn good. But I, like a lot of the other sick SOB's hanging around here am always trying to get that little bit more out of the old sound well.

Clint, care to comment on this? JC, do you have proof of this? Where do you come up with this stuff? I highly doubt this. And add thousands? Nothing like just a slight exaggeration huh?

I read it somewhere. Can't remember :confused:
I would like to know how you guys didn't get the hum. Can you tell me how you hooked it up? I even went so far to buy a Tripplite Powerbar 10 and still got a hummer.

yeah thousands may have been an exaggeration. However, Denon has not endorsed this biamping. I think I recall Zone 2 and 3 having different specs and non digital or something to that affect.

Clint DeBoer are you out there?

Think again. :) The reason why you cannot distribute a digital signal has nothing to do with the amps. By the time the signal hits all seven amps it's already analog. Clint can you comment on Johnny's earlier post, #5?
