I have a Pass Labs XA30.8 and see they recommend balanced cables.
I am using RCA interconnects as I have high-quality silver RCA cables and they sound superb. I use the Pass labs XP12 (and have a loan XP22 here) and I can I use balanced cables from my DAC (Audionote DAC4.1x) into the Pass preamp. My preference is for the RCA cables as the interconnects are much better quality than my balanced (Nordost and TA).
The pass preamps work really well into their power amp, which is not surprising. I guess it depends on the price difference but in my case, the difference between the AN4.1 DAC balanced vs RCA is not sufficient to make me want to use balanced.
