Lightly used Sutherland Battery operated phono stage. Batteries last over 1200 hours according to specs. Extremely quiet. TAS and Stereophile recommended. Lovingly cared for. Perfect except for small bend in rack mount only visible from above (shown in picture) Rating it as 7/10, but honestly you will not notice it - I am picky. Unit was purchased with flaw from manufacturer at a small discount - which is reflected in offered price. Will consider package deal with Pro-ject Xtension and Benz Micro Glider S medium output cartridge.
