Lej1447, just some food for thought..... maybe it's not the amp running out of steam, but possibly the wall? I use a Denon 3803 for my HT. It is rated at 105wpc. I am using said amp in conjunction with 89db efficient speakers in a room just slightly larger than your room configuration. Since that room only has 15 amp receptacles, I find that the amp is fully capable of drawing more power than the wall receptacle can provide.
Maybe a regenerative power conditioner may be in order? If you are trying to avoid more amplifiers (space limitations, heat, interconnects, etc.), could this possibly provide you with an alternative? Needless to say, all of your HT components will benefit from a stabilized power source. Power "draw down" or "sags" will become virtually nonexistent. You will find that your amp will sound like it's on steroids, not to mention the clocks in your DVD player and receiver will become much more stable.
You will probably not notice a major difference in SPL by going from 100 to 200 wpc. But, stabilize the AC power and you will notice that extremely dynamic passages will become much more effortless for the amp to reproduce. You would be surprised. That little Denon is probably capable of drawing as much as 1000-1200 watts from the wall at high volume level passages. Unless you stabilize those types of power draws, the amp will have a tendency to sound it's clipping when it is actually not. This also wreaks havoc on your digital section since the DA/AD clocks need a stable voltage supply.
Something like an Exactpower EP-15 or Accuphase will provide you with a very stable 120v/60 cycle power waveform, no matter what type of load you put it up against. Again, ALL of your HT components will benefit from this type of power conditioning, the unit will not occupy a lot of space, will generate virtually no heat, and would probably be extremely cost effective, condsidering your other options.
Also, if you decide to upgrade to other components at a later date, they will all benefit from stable, clean power.
Just a thought.
