Regas own flat cable which you can split down the middle to get two runs, if you're not biwiring.Sorry, I can't remember what its called though, you'd have to google to find out. The RS 1 which I used to pair to a Creek 5350 produced exceptional resolution & finesse....that's coming from someone who also owns Lowther dx4 Medallions single ended with parallel 2a3 tubes,which it matched for detail.Anyway,just my 2 bob's, good luck in your endeavors!
