B&W HTM1D and Parasound A51?

Well, the planned update is 802D's and the HTM1D down the road. Right now I just have some low budget RTi12's doing the job with some Rotel RB-1091's powering them (500 watt RMS). The planned update for the L/R channels will most likely include an update to the amps as well (getting new JC1's). I'm planning on using a parasound amp for all the surrounds, that is for certain. Right now that's just some polk RTi6's (no need to update those anytime soon). As I've read it's pretty much only important to voice match the 3 fronts and not the surrounds. With that said the A51 is plenty of power for all of my surrounds. Is the extra channel going to be powerfull enough to drive the HTM1D? I hear that the HTM1D is basically the same speaker as the 802D which I know are very very demanding. Primary listening is going to be 2 ch stereo with multi-channel movies on rare occassions.

To sum it up what I'm looking at:

JC1's or 1091's and 802d's for L/R
A51 or A21's for the surrounds (initially RTi6 polks, later B&W's)
A51 or JC1 for HTM1D center <--- The question, will the A51 cut it also powering the surrounds?

Perhaps while you are at it you can answer 1 or 2 of my other parasound threads. Mainly the C1 vs C2 vs waiting for HDMI 1.3

I'll have to see if I can't do demo at the dealers between the HTM1D and HTM2D! I hear the HTM2D is a good match for the 802's but the HTM1D is in another class. If I can't tell the difference though I'll go the HTM2D route! Thanks for all the help!

I've thought about another option, if I'm going with JC1's up front would my old 1091's be a good option for the surrounds? A51 vs 1091's, any opinions? I assume I could get another pair of 1091's for near or less then cost of the A51. This just leaves the center channel. Any good parasound options for it? Would bi-amping an A21 be worth the effort?
