Amplification options for avr-3311 5.1 w/energy

I have currently updated my home theater with the options givin at hand. What I am looking to do is amplify the system. Not sure if I want to amplify the rear surrounds but here is my current set up

Denon avr-3311
Energy C-C100 center channel
Energy Audissey a3+2 (bi amped from denon)
Energy 10' sub (active)
Energy C-100 surrounds


Should I get a multichannel amp and power up the 5.0 system or bi-amp the a3+2's and center channel


I am currently looking at a sunfire 200, Outlaw 7100, or I have found a guy on CL selling Denon POA-8200 and 8300 for a great price..


Yet I still dont know what would be the simplest set up. I watch mostly movies on here and listen to the occasional RUSH cd since they are my favorite band EVER

The bi-amp configuration on the 3311 isn't buying you any extra power and likely neither will the amps you're considering ... rather bump up to something like the Emotiva XPA-3 instead.

I checked out these amps and they look pretty nice. Is running 200 wpc into my center channel rated @ 85 watts pushing it headroom wise? Maybe I should look into a 2 channel amp for the a3+2's?

Unless you're running at full max output, your center won't see 200W. That said, a 200W input could probably damage the speaker if it's maximum input is 85W (you are talking more than double).

So then maybe a 2 channel amp would be more appropriate for the a3+2's and leave the 123 wpc receiver to hand the center and surrounds?

Yes .. as they are 6Ω rated while the other speakers are 8Ω rated a 2CH amp would be more appropriate if you feel you need more power.

Well I guess that is what I am suffering from. To my ears as now, it sounds good, I get very decent sound staging with them positioned 12 ft away from me and less than a foot from the walls. I guess I am just a typical man looking to better my experience with these speakers. My entire room sits about 25x20 with high vaulted ceilings so I know the 125 wpc with these A3+2's are probably small for what the room they sit in but I still get about 109db at my listening position. anything more than that just fatigues my ears and frankly gives me a headache. I guess I am chasing more sonic capabilities out of these speakers with external amplification. Question is do I really need it?

No - 109 dB is giving you a headache because it's well beyond the threshold of pain and well beyond what you should be exposed to without protection. Either turn it down and preserve your hearing, or keep cranking it up and it won't matter what you do - you'll have long term hearing damage and so on in a fairly short period of time (we're talking weeks here, not years).

109 dB is also above any "top end" for reference level output (105 dB should be your peaks, 85 dB should be average - I personally feel those levels are too high (for prolonged (As in daily) use - this is based on OSHA/CCOHS data as well) and suggest something in the 60-70 dB range for average, if you can't hear that over whatever background noise you've got, deal with the background noise, don't use the amplification to "mask" other noises - it will still damage your ears).
