Balanced cable between Pass X350.5 and Cary SLP05

I'm running Dynaudio Confidence C1's using Tesla Accelerator's from my Pass. My Cary is using a high quality balanced cable with Furutech Rhodium connectors.

It's the only "good" balanced interconnect I own. I need a reference, or, a balanced cable that I can use to gauge what my other cable(s) are doing. I am a bit of a experimenter with cables, often building my own. But with this quality of gear, I need to know where I'm at.

So, I'm hopeful under a $1000 used, hopefully way under. I guess I'm fearful I'm not getting what this equipment has to offer. In A-gon members opinions, would work well with the Pass?

I'm thinking as well that the Pass and Cary might be mismatched as I rarely take the volume control past 1/4 turn. Impedence mismatch?

My source is a hotrodded Oppo BDP83SE, and soon to be a PS Audio Perfect Wave DAC (with no cables to connect!)
