Need help deciding on Rotel Amp for 5.2 sys


Our home theater was created on a single income Family budget. When it's my turn for a good action packed LOUD movie, there seems to be a lack of power for me. Listed below is my set up. The amplifier I am going to purchase will be the last good effort before retirement next year. Fixed income will not allow the goodies. Thank you.

Room size: 11 ft wide(Monitor) x 25 long (seats)
Integra 50.3 7.2 bi-amped front
B&W Speakers 684 Towers (bi-amp) Front L/R
CM60 Center
8 in. ceiling
Klisch Sub Two 10 in. power subs

Should I buy a 3 channel for the front and use 130 watts on two rear ceiling speakers?

Buy 5 channel 200 watt and only use the Integra for the pre amp?

Would like to buy a pre owned upper end unit.

Thank you

As mentioned don't just look at Rotel.

Here is a 5-channel B&K that should mate very well with your B&W's and offer tons of headroom to blow you out of your seat.

There are also a couple of Proceed Amp 5's for sale here on Audiogon that will easily complement your system.

Totally agree on the B&K brand, had intended to mention them but was at work. Hence the typos in my previous post. I also have B&Ws in a home theater, and also suffer from a lack of power. I have chosen to place all my attention into the two channel system for now, so my HT sound is still lacking, but only have so much to spend. Please post how you decide to go so I might live vicariously.

Are you running the left, center and right speakers full range?
I agree with Bob. The front speakers should not be running full range, as this will be a waste of power since the speakers will have very little or no output in the low bass range. Did you manually set a crossover for the front or just do auto set up? Also, what is the model of the Klipsch subwoofers?
