The Raven 10.5 tonearm has a "captured cable", so there's not an aftermarket phono cable; though, if I was in that market, I'm all about WyWires right now.
Great system! TW Acustic AC-3 is fantastic TT and Raven Phono is very good phonostage, but I wish you could try Whest Audio PS.30RDT Special Edition or MC REF V phonostage with your current analog setup. You'd be impressed. I had a chance to audition both TW Acustic Phono and Whest PS.30RDT SE side by side. Anyway, what phono cable are you currently using? I've got Ortofon Windfeld with Feickert Blackbird TT and Whest Audio PS.30RDT SE. It's fantastic combo, but planing to upgrade tonearm and phono cable. Could you suggest any options?
