I wouldn't spend your money on cables, instead put it towards an outboard Dac which will improve the sound of your Node by an order of magnitude.

Looking for some suggestions on RCA cables between BlueSound Node 2 and preamp. At the time I’m using Transparent Audio Super MM2. I was looking to upgrade to Transparent Audio Ultra MM2 RCA but if there is something of better quality at a better price point, I’m all ears. Any suggestions???
