Tfee,
I have had the Parasound JC-1's and they are a great pair of amps. Given your equipment, i feel they should mate very well. JC-1 is voiced toward the warm side and with the 400 watts should push the B&W's nicely. Levinson 436 is a nice amp as well as the McIntosh gear. The Lev and the Macs are not as warm sounding as the JC-1's. Be careful however, the JC-1s will need to be left on for a month straight before they will sound their best.
