Bluetooth vs Turntable Recommendations

Hey, 

My system consists of a pair of B&W 630's, an old Denon 50 watt reciever (DRA-550) from the mid 80's, a Marantz CD5004 cd player, and now am interested in maybe getting a bluetooth and/or a turntable upgrade.

I'm going to demo a Project Debut Carbon and  a Technics 1500C Turntables, but if I'm not happy with the quality I'm probably going to explore Bluetooth options.

Any recommendations would be be greatly appreciated,
