This is a fantastic sounding preamp with a complete variety of balanced and single ended inputs and outputs..
Transformer coupled tubes are simply the best and this is the best I have heard!
Check the reviews on this and you will see that it is often compared favorably to the top tier Shindo preamps.
This is a recent model which has the new Allnic logo. The serial number shows it was manufactured in December 2015. Tubes are very quiet, zero tube noise. I have been swapping it in and out of my system using it with ARC ref 75se and Audio Note amps, and it sounds great with either!
Original box is in great shape.
