@inna +1 "Accuphase stock cords are not too bad”, indeed! Accuphase cables are very good electrically speaking! More expensive cable upgrades cannot not change sound anyhow, assuming no other issues like RFI nose etc. In analog design PC is at bottom of design pareto chart, which specifies impact of every chain part to final result.
+1 "The most important cable in the system is tonearm cable not power cords” yep, in analog sound system phono cable and tonearm wiring, on top of cartridge and tonearm itself, are very important parts!
