Dan-ed, take a pill. I'm didn't mean to contradict you - I am just relating my DIY experience. I did not design my phono amp and made no claim to.
What I did was to implement an existing design (Thorsten Loesch's redesign of Arthur Loesch phono) and made it sound "great" to me. It was no more complicated than the application minor circuit and parts changes until I heard what I liked - a minor feat that I feel is well within the capabilities of any reasonablly intelligent stereo nut. I tons of online help - but the actual building and parts choices were mine.
Check out Steven's site here: http://www.izzy-wizzy.com/audio/preampnew.html to review a very interesting example of building and rebuilding a phono circuit to try to bring it to perfection. What Steven has done is exactly what commercial manufacturers do to create new iterations of their products. Many times this process is more about perspiration than inspiration.
