Bottom Line:   
I am very pleased with this tube preamp, it is of excellent build quality. Does not get to hot. Sounds wonderful with tube amp or ss amps, it makes ss amps sound much warmer. I would say it is in a different league from most preamps. It sounds very realistic and warm, voices are sensational and so are strings, bass is good to. I heard it with 3 different amps and it improved the sound of all 3.
But my first choice was with the Graaf gm 20.
