Denon 2809

I am a newbie. I have had this Denon 2809CI for some time now. But, when I play it loud it will shut down in 5-10 mins. Since new. I have Deftek BP7006 front, Deftek BP2002 center, and Deftek BP (?) 2004? ( bookshelf ) can not find the model# on them. I am looking at upgrading to a Denon 4520 or 3313. Any suggestions? Or something that can drive these speakers like they are meant to be?

I have the 3313ci and love it. You have to do firmware updates I've found for optimal performance. I power deftechs in a 7.2 and it is too loud past 70%. The room is 15x25. You can see in my build. Also it needs plenty of air.

Re: Denon 2809

The Denon 3313ci with 125watts per should be plentyto drive 7.2 Def Tech speakers. I have the older Denon 3805 with 120watts with Focal subs and B&W satellites and I can drive at natural sounding levels with plenty to spare. You can buy Refurbs from Accessories4Less 3313ci for $629 and the 150watt 4520 for $1500. You may get a few extras in all areas of the 4520 but hardly worth the $900 extra or..., If i had the $2400 for a new Denon I'd throw a few more $$$ and buy a Krell

Regards

Re: Denon 2809

Your current Denon AVR 2809CI is a little underpowered Bench tested it will do about 95watts into two channels and it drops from there as you run more. You might just be better off investing in an external two channel amp like the Emotiva XPA 200

Home theater:
Onkyo 805, Yamaha YDP2006EQ, Samson Servo 600 amp
3 EV Sentry 500 monitors across the front, 4 Mission 762i's Surrounds, SVS PB13U sub, Panasonic BDT220, Harmony 1100, Nintendo WiiU
Panasonic PT-AE8000 on a 120" 2,35:1 fixed screen

Living room system:
Sherwood/Newcastle R972, Mission 765's, SVS SBS02's, A/D/S MS3u sub, Yamaha YDG2030EQ
Yamaha KX-393 Tape deck, CDC 805 CD changer, Panasonic BD60, Sony turntable PS-T20
Panasonic TC-P50ST60, HD-PVR & WDTV Live, Harmony 900

Re: Denon 2809

ok. Since I am still try to learn about this audio stuff. I am running 2 front, 2 rear, and a center. Is this considered a 5 channel system that can do 7 channel? ( 2809CI ). Then my question is, 2 channel only runs 2 speakers?

Re: Denon 2809

Hey Tom,

Tony has an interesting idea, especially if you plan on growing your system and who doesn't like that idea. My thoughts and I believe Tony' as well - Denon offers Pre-amp Outs on many of their models. Now you ask, what are the pre-amp outputs and what can be the advantage.

Well on the back panel of many Denon AVR you will find RCA connectors that allow you to use the pre-amp section of the Denon amp and connect this pre-amp section of the Denon to your choice of power amps. You could buy a two channel power amp or a pair of exceptional quality monoblocks or a nice Krell 5 channel power amp or even 7 channel. This is an exceptional upgrade path.

Now with the reduced power demands on your Denon AVR power section you have greater available RMS wattage to divide between the fewer speakers being driven.

FYI - something to think about

Re: Denon 2809

Thank you. I was going to ask, " how to connect an amp" thank you for your great mind reading skills. lol. The wife really does not appreciate audio like I would like her too.. So I have to keep things kinda on the down low, and sneak in a piece in here and there. And if she finds out, tell her it didn't cost much. It's ok honey. Let me show you how much better your favorite movie sounds. So I did look up the Emotiva. Looks like a great option.

Re: Denon 2809

Hey Tom

FYI - I do not know the history of your AVR I do not know if somebody has tinkered with this Denon 2908 or 2908ci. You should not attempt any changes until you are sure you understand the process completely and accept full responsibility. I cannot know the condition of your Denon AVR and I cannot watch to be sure you make proper connections.

You will find the location of "Pre Outs" on page #20 of your owners manual with a brief description, I believe.

I understand the Emotiva equipment is nice and becoming popular. I like the prices. Hope you enjoy the results of your labor.

Enjoy

If you got a Krell you would then need a power amp too... I would be suprised if you could get Krell amp and processor for double the price of the Denon 4520. I am not saying the Krell is not better but that it is in a dif league. Personally if I had the kind of cash to buy Krell I would go Classe.
