I have 2 of them. One I use at home with the Don Sachs line stage. The other I use at audio shows to demo the Bob's Devices Step up transformers. I have used many phono stages in the past and like this one a lot. I also currently have a Hagerman Trumpet which, in my opinion, equals the sound from the D. Sachs Phono stage. I have tube rolled both of them with Amperex Bugle Boys on the input tubes. I am very happy with the sound from the D.Sachs Phono stage. I have had Don change the gain switches on the phono stage to include a 100k setting to use with cartridges that have a high internal impedance and low output with a SUT.
