Pass Labs Xono - Any users out there?

I had the unit for about a year, in the version with the smaller power supply, which I used with a Pass X-1 line preamp (same version). Both were excellent in every respect. If you have any specific questions, let me know.

As to the comparison with the original ONO, I've had both, and the X-ONO was noticeably richer and warmer. The ONO tended to be a bit on the lean, dry side. I used the X-ONO both with a SS (the X-1) and tube (Lamm L-1) line stage, and thought it worked beautifully with either. The only caveat I would make is that I found the sound noticeably superior using the balanced outputs (yes, I know its output is higher using the balanced outputs; I mean even after you compensate for that difference).

I got the same info from Pass. The person I spoke to told me that on his own system at home he ran both the X-1 and X-ONO off one original small power supply and didn't hear any difference, and that if he had, all he had to do was take one or two larger power suppies home. At one point I ran both the X-1 and X-ONO off one smaller power supply (space reasons) and I certainly didn't hear any differnce.
