Khozmo Acoustic Passive Preamp with resistor and shunt upgrade

Bought for an alternative set-up that never materialized. I have auditioned it in my main system and found it impressively transparent. It comes in the state in which I received it from Poland last year, hence the 9/10, but it wasn't made from high-end perfectly finished materials. That said, it looks good and is solidly constructed. As with any stepwise volume control there is clicking, but no more than I hear from Music First or Wyred-4-Sound units. No special box was included.
