I know it isn’t the newest preamp on the market, but I recently became aware of how novel this unit is. A customer reached out looking for info on this and an Art Audio preamp. The thing that is so cool is that it is built around a 45 tube. Has anyone heard this unit. I am thinking about bringing it in and pairing it with a Chord Ultima 6 Power amp as my alternate system. I sell both so pricing is not a stress point for me. Just am trying to find someone who has heard it besides the folks at KR.
