Multichannel or Mono amplifiers

I think I want to add more power to my system. I currently have the Denon avr 4306 with Polk rti12's for fronts, csi5 for center and 2 sets of fix3's for surround and surround back plus a Velodyne cht-12 sub. I have the fronts bi-amped with 2 outlaw m2200's on the lows and the Denon on the highs and love the results. I am thinking about getting 5 more monoblocks, 2 of which I would use to bi-amp the rti12's and the other 3 to add power to the center channel and surround channels leaving the surround back channels on the Denon. What is anyone's thought on this. Should I use monblocks or a 5 channel amp?

Have you considered placing monoblocks in the rear, near the surround speakers? I've read articles from supposed experts saying that it is better to run the interconnects from the pre/pro back to the amp in the back of the room to power the rear speakers, as opposed to leaving the amp in the front of the room and running 20+ feet of speaker wire.
Has anyone considered this and tested both options?
I would think the longer interconnects would be a good option of the pre/pro and amp have balanced XLR connections - not so good for unbalanced RCA connections.
The issue with longer speaker wire, esp. if using higher guage, is resistance and lower volume.

At distances of less than 40 or 50 feet, I doubt it would matter which method you use. At longer distances, the interconnects may be better, due to the added inductance and capacitance of speaker wire in long lengths, which will start to roll off the high frequencies.
