Advice needed: Jamo or B&W surround speakers?

I desperately need advice. I want to upgrade my 5.1 HT speakers and there are two offers on AVSA that I am interested in, but cannot decide which one to go for. The first is a Jamo C809 system (+/- R35K) and the second is a B&W CDM system (+/- R25k). My TV lounge is a large room with high ceilings. My AV receiver is a Marantz SR7005 and I am waiting for a UD7006 universal disc player. The system is used mainly for movies and music DVDs, but I do occasionally listen to CDs in Pure Direct mode. Any suggestions, especially from forum members who are familiar with these speaker packages, would be greatly appreciated. Thanks in advance.
