Is the 33 not providing enough volume?

need advice for an amp
This is my set up
Sony 55nx810
B&W cm9s Left and right
CMC2 center
ASW10 sub
DS3 Rears
Pioneer VSX-33
Oppo BDP-95
PS3
HD cable box
I have the cm9s bi-amped right now and I am looking to get an amplifier
I have looked at Anthem, Arcam, Primare, Marantz and Emotiva.
We watch mostly movies, sports and play games. We listen to some music but mainly we do other things while listening to it.
The wife is very much about bang for the buck kind of person so any advice and things to consider is great!

Well the big thing to me is longevity and when I have been watching a long movie or a game it gets pretty hot. Some of the people I have talked to have said getting an amp will help the receiver out and get more of the true power at which the speakers can preform. Whether or not they are blowing smoke at me is conjecture, but I figured it was something to look into either way.
Assuming the receiver has pre outs, a 2 channel amp for left and right fronts would take some stress off the receiver, and leave more oomph for the remaining channels. I'm tempted to suggest an NAD 2100 or 2200 since they have plenty of headroom. It might be smart to hook up an amp temporarily that has a good power readout or clipping indicators, and get an idea of how much power you really use.
Are you sure the heat being generated is coming from the amps rather than the video boards?
Great point. I have found thats where most of the heat is generated in the receivers i have used.

Hmmmm is there a way i can check to see if its the video processor? E.g. Play music through a cd player for a bit?
You could pull the cover off, and get a Radio Shack (or other) laser temp thingie. But really, look at a modern AVR. It has a ton of ASICs (Application specific IC.)
It has DSPs, a processor, video chips, and HDMI chips. All those chips run hot. Idle heat from the amps will depend on how much it's biased into class A I believe. Be nice to maybe have a set of relays to shut off amp channels, but seems only a few AVRs have it. I don't worry about it when using my Z7 as a processor.

My Integra DHC 80.2 still gets hot. It is hardly every "truly off" either. Its Zone 2 is constantly hot for a Popcorn Hour to my 2nd zone.
Why are people so afraid of heat? It is perfectly natural for some amplifiers to produce heat even while not driving anything. My Adcom amplifier stays very very warm when just on and gets very hot to the touch when driving my speaker loudly. Not only that but my Adcom amp is on 24/7. That's right, I never ever shut it off. It has been on everyday since I bought it about 10 years ago. My Yamaha receiver gets very hot when I'm listening to anything at a reasonably high volume level. Come to think of it my Denon 2801 before that ran hot, and so did my Onkyo TX-8511 and both of those receivers are still operational and the Denon is still in active duty.
Do not be afraid of heat. It is perfectly natural. Just make sure that hot electronics have room to vent out all that heat. Do not put them inside enclosed media racks with glass doors. Do not put other components near or on top of them because you risk damaging both the amp and the other component. The only time you must fear heat is when you have smoke and then fire on top of heat.

Have you looked at it's design, schan? Maybe it does not vent heat very well?
The point(that I was trying to make) is that it is a pre-pro, not a receiver...the video board/DAC's and everything else...get hot. It isn't just the amps.
Matter of fact, if you want to talk about opposite of "norms"...
The Sunfire Cinema Grand NEVER gets hot. And I've let it run well above reference level for 30 minutes(I was in the driveway washing the car with windows open).

Advantage of a "class G" amp I guess. Very efficient, not a lot of wasted energy. One day I will have efficient and hopefully lightweight amps for all channels, but I am sort of stuck with my XPA-3 for now.
Out of curiosity, what's the difference between the cinema grand and theater grand amps? Anything signficant?

I think there is nothing different. Depends on where Bob got the financing from/who he worked for at the time.
Been a while...was Sunfire "him"...or did he just work for Sunfire???

I always gathered that Bob started Sunfire. Who knows with him. He seems to be spending his time lately building very cool looking tube amps.
Correct, after he lost "Carver" he had to use a different name to sell his amps. Of course now, he's no longer associated with Sunfire.
True enough, with the caveat that watts converted to heat are not available to your speakers. It's called inefficiency. Also not very "green" for what that's worth.
The Cinema Grand models have a little more "beef" in the output stages, use an earlier "pure Carver" design. The Theater Grand models are also great amps to be sure, and in real world use probably just as good. Lets face it, how often do you actually call for 200WPC?
I've had both and heard no difference other than my CG has 400WPC and the TG had 200. Also have a couple Carvers that sound pretty similar. All of Carver's SS designs are essentially designed to max out the available current from a 15A circuit.
