Axiom Home Page Forums General Discussion Home Theater Denon 3805 Bi-Amping

After reading all the hoop la about being able to bi-amp your fronts with a left over channel on the 3805, I decided to try it out. I have been playing with this since yesterday. I have taken SPL readings and a ton of other things and I hate to say it but not once have I come close to the +3db people are reporting. It sounds no better or no worse then when I'm running the regular L&R amps.

Given the hype surrounding this, I was expecting more. I also did some non scientific tests using a voltmeter to the speaker leads and using the formula voltage times voltage divided by impedance to get a quick idea on the Denon's actual power output with 5 channels being driven. I did it about a dozen times and we can't get more then 75 watts per with all 5 being driven. My number is a little lower then what Secrets got but only by about 2 watts. It should be noted that using the above method is not that accurate but it's also not that bad either. We did the same thing with my HALO and we got numbers that almost matched what Parasound has in the manual.

I have no idea why I'm doing this other then the fact that I was bored!

Is there a better way to test given the fact I don't have any testing equipment other then a voltmeter?

Ok what's up here? You guys ignoring me or am I the only one here who has tried this?

Yes.

I'm ignoring you

Well I was thinking of trying the bi-amping thing at some time for fun, but I think you just saved me from wasting a bunch of my time.

Certainly appreciate hearing about your experiences with bi-amping a Denon though. Jag

Bi-amping does work but using the 3805 way that everyone has been running on about is to me at least a waste of time. Which sucks! I was looking to get a little bit more punch out of my fronts and I thought this would do it.

So I went in another direction and sold my HALO and picked up an older Parasound 2205A for all 5 channels. It's been my favourite amp for years and for whatever reason it sounds fantastic with Monitor Audio speakers.

...............................Now the bad part.......(or is it?) Wife hasn't talked to me in almost 2 day's since she found out I bought yet more stuff!

Have you said: "Just get it all over with honey, and spank me already."..?

lol I'm not so sure she would look at that as a punishment!

It's all good now anyway. She broke the ice last night by telling me she spent an obscene amount of money on a new ski jacket. Payback I guess!

Anyway, I always say this but anyone looking for what I consider to be a bargain in power, look at Parasound. This amp is simply outstanding and for whatever reason, it has a sound all it's own.............and no it's not in my head so all you pocket protector types please save your every amp on the planet sounds the same speech for someone who cares!

Nothing like offering only one side of a belief then shutting down debate with an insult.

If those who don't hear a difference in amplification circuits with similar SNR/power levels are pocket protector types, does that mean those that hear a difference in amplification circuits without any reasonable evidence why it would be so the audio rosary and chants type?
