Here is one idea that is much cheaper than the other options discussed but MUCH more difficult to implement.
Hard wired low RCL cable: 1 uninterrupted run of cardas litz straight from the cartridge into your SUT with shield attached only as it comes out of the base of the tonearm board, than another very short run of low RCL shielded and hardwired into the phono in. Many options are available, cardas is one. No need for expensive connectors, when your hardwired, of course you give up some flexibility in this configuration. I dont know that you can get warmth out of a cable, but your equipment can accomplish this when connected with cabling that is transparent. Just my 2 cents. Best of luck!
