Bryston 4bsst or CA 300 to Drive Soliloqy 6.3s

Hello

Would appreciate any advice from Soliloqy owners. I am considering either the Bryston 4bsst or the Classe CA 300 to drive my 6.3's. I am using a Bryston SP1 as a preamp with Harmonic Tech Truthlink interconnects and Signal cable biwired speaker cable.

Thanks
Brent
