Well I have been in design study mode for for the last year. I really want to step up in the Line stage department, and go 2 channel. There are a lot of smaller companies that make great gear, but it is way to cost prohibitive for a lot of us. I have been fallowing many of the great designers like Wat Jung, Nelson Pass, and Peter Daniels. These guys really put out some great stuff, and I have learned a lot from them, and watching what you guys like here(thanks Guys/Gals). I have been helped with a couple designers, and have came up with what should be a great flexible product. I just finally ordered custom PCBs made to my specs. They should be in Tuesday or so. For now I am going with a cleaned regulated 120v power supply(external). I am looking into battery power supply designs with a kick from madmax. I have been stuck in 12dc design mode(more complicated/noisier/lower performance), but after a doing some research, and again a kick from madmax I'll be working on a battery PS in the future The Pre is going to be selectable passive/active/tube line stages. I have collected most of the parts, and have ditched the crappy rat shack proto boards. The XO parts are from Marchand Electric. You just can't beat the price performance that these things offer with a simple OpAmp upgrade. All OpAmps are going to be Burr Brown 2134 designs.
