B&W HTM1D and Parasound A51?

Parasound dealer here. Let me understand your system first. Ideally, you would like the front three speakers to have the same power across the frontal stage. What are you using for L/R speakers and powering them?

In most cases the A51 will drive most any 5 channel system. However, the frontal stage usually demands more current than your surrounds. So, depending on you speakers, the JC1's might be the better choice. Give us some more detail and we'll direct as appropriate.

What is your dealer telling you?

I've already responded to your other threads on on the C1 and C2. :-)

Since your primary interest is going to be 2 channel. I would probably direct you to using the JC1's for the 802D L/R and let the A51 run the center channel and the surrounds. You could always add another JC1 if your interest changes to HT over 2 channel.

Nick made a good suggestion stepping down in center speakers. That is certainly an option as well.
