Turntable to UQ2 interconnect ideas

I've just upgraded my turntable from an RP3 to a Project 2Xperience SB. I've also got a Graham Slee Gram Amp 2 phono stage between the turntable and my UQ2. 

At the moment, I'm actually running the (what looks like a decent) cable that came with the turntable to the Gram Amp, but a basic throwaway patch cable for the final link.

What kind of cable ball park am i in here? I've also got a Dynavector 10x5 cart on the deck, so the only bottlenecks I can see are the cables, and just maybe also the phono stage - but definitely the cables.

Am I still in Chord C-Line territory, or would that still be holding the system back? Would a Cobra Vee 3 be overkill? I also recognise that ideally I'd use the same cable from the turntable to the phono stage too (and find another way of fixing the ground issue. 

Anyone got any other suitable suggestions?
