"jpmanomet" is right on target with Mogami. For interconnect cable I recommend the W2549 matched with the Neutrik NF2CB RCA's. The Mogami W2549 is a microphone cable with 2 jacketed conductors made of ofc.
The soldering required for the neutrik nf2cb rca's is not easy as you have to solder the braided ground before the 2 conductors to the center cup. You could opt for the Rean Neutrik NYS352G Gold RCA's that use a satisfying/satisfactory crimp for the ground.
Once broken in, these cables are stunning and deliver the goods!
