Turntable Distortion

Recently decided to get into vinyl a bit and found a free B&O Beogram RX-2 w/ MMC4. I bought a Cambridge Audio 640P and connected to my Creek Destiny (the Creek does not have a pre-installed phono board).

All records sound overdriven even at low volumes. Is this likely a problem with the TT (cartridge/tonearm setup, turntable itself) or the preamp?

Thanks.
