Al - One review of the Benchamark claims way better performance at 0dB settings for XLR (four jumpers inside) than any other position (-10, -20, -30). I can hear a little livelier sound at 0dB than -20dB but -10dB is much worse and my 0.5m cable has total of only 6pF/ft x 1.5ft=9pF.
Benchmark stated in manual that for XLR:
Setting (dB), Output impedance (ohm)
0 60
10 1600
20 500
30 160
and -10dB is really bad. If you're concern with it - get DAC1 USB. I think that pre has also LM4562 on the output and different divider but verify. I'm not sure how better it is - will check their website for the manual.
