hi - i can tell you this...it was just chosen by Ricky Martin and his engineer for Ricky's vocal preamp.They compared it to 9 other preamps. And if you can hear the 3/4's of one db difference at 40,000hz between our unit and a real 80 series pre, I have a job application for you. As far as rumours of reliability problems, in the last year i have recieved 3 preamps for repair, and one had nothing wrong with it. We have sold over 500 units. The first series (I guess they're "vintage" now) were All hand wired and used some old components as well as edge connectors for the line amps. Our new package (well about 5 years now, actually) is all new components excepting the transformers, and they have proven to be very reliable. The electronic circuitry is IDENTICAL. The newer style unit uses a more rugged power supply and an added 1/4" unbalanced out in addition to the normal balanced xlr....you can see photo's and get more info at our website.
