I finished construction of both my SC-1 mk500 kits. I decided to build one with the transformer and one without. They both sound GREAT and I think I'm going to spend the afternoon experimenting. he unit with the transformer has a nice thick, but not exaggerated, sound quality.
The fivefish kits are very high-end, the PCBs are very thick and sturdy, the coating is excellent and very resistant, they look very well done, unlike anything i have ever seen before. - J.Gomez, Analog Recording Forum
I bought an x12 about a month ago and i've finally gotten to play around with it a little bit and i have to say that it's killer on my snare with a Sennheiser e604. I'm actually selling my other preamp and i'm thinking of picking up some more of your units. - Roy H, Canada
