I work part time for Audio Doctor in Jersey City., pretty amazing shop.
Huge collection of high end brands with an extremely knowledgeable shop owner.
As per cabling, it depends on price. We sell the Wireworld cables which bested the Nordost, Wireworlds are very transparent without any brightness, we also sell Enklein cables whose power cords are amazing, also their interconnects are really good.
Have you tried power conditioning and vibration isolation, the Audio Magic conditioners are really fantastic. We have a number in the shop it all depends on synergy.
With the right combination of power cords the player is really amazing and is quite a bargain for how good it sounds. Sorry to not be more specific we would have to know more before recommending which cables etc to use.
