Soekris DAC1321 Discrete R2R Ladder DAC with selectable FPGA filters & Digital Volume

Original owner, virtually brand new and mint, only a couple months old, selling because I just bought a house and own too many DACs. Buy this before I change my mind. It's very good. 
This is a fully discrete 25 bit R-2R sign magnitude DAC, built with two hundred tiny and very precise thin film SMD resistors. The line output buffer is a high performance zero feedback design built with discrete parts. The main power supplies are ultra low loise, low impedance and very fast, also built with discrete parts. Inputs are a USB interface in both PCM and DSD formats, SPDIF and Toslink. It is then buffered and reclocked using a precise and very low jitter oscillator, with the digital processing done in a programmable FPGA chip, with 4 selectable advanced digital filters and a digital volume control.
I paid $730 total including shipping.
