Purchased from Larry Moore, this piece had been in his personal use. Tube buffer with integrated USB DAC. Uses 12A4 tube with mu of 20 or 12B4 tube with mu of 6.5. Accepts direct USB input to the DAC, and three other RCA inputs. Two RCA outputs, one of which was added after purchase. Very accurate, neutral buffer with excellent sound. Purchased in 2011.

http://www.ultrafi.biz/ Very nice granite side panels and clean profile. The internal DAC shares with the Musicstream DAC and the USB interface borrows from Empirical Audio technology as I understand. The sound will not disappoint - provides quiet, layered, wide and deep soundstage.
Asking: $500, Purchase price: $1250.
