Frank,
I have seen and heard an SU1. It sounds just fine and very quiet (no hum pickup). It is very big. I'd say 12" wide by 10" deep by 8" high (30 x 25 x 20). Must be heavy, too. There is a lot of shielding and the transformers themselves are supposedly quite large. It's quite unique.
My guess is that the gain is about 26dB (20:1), having compared it to my new step-up. RCA jacks in and out.
