Speaker Upgrade Questions

[Wilche]

Correction on the Subwoofer proposed for my upgrade. It should be the Rel B3 NOT the Rel B1. Sorry about the mistake.

I have a few questions about upgrading my current system. This is what I have:
Fronts: PSB Synchrony Two's
Center: PSB Synchrony C One
Rears: PSB Synchrony Two B's
Sub: PSB 6i
Receiver: Marantz SR-8002

My plan is to upgrade the PSB Fronts and Rears to Synchrony Ones and to also upgrade the subwoofer. The dealer recommends the Rel B-1.

Will the Rel B-1 integrate well with the Synchrony speakers?
Does anyone have experience with the Rel B-1?
Can my Marantz SR-8002 handle these speakers. Plus I intend to add PSB Synchrony One S surrounds at a later date.
What is a realistic price to pay for the Rel B-1, if I go that route?

When I bought my receiver and speakers, I expected to use them 70% for theater. My usage is now about 65% music and 35% theater. The music being mostly classical and jazz. Although my last SACD purchase was Pink Floyd.
