I dug out the sim I made last year for the Jung super reg that I thought about using for my phono pre (in the end I went with the standard 7815/7915 instead) but abandoned because I knew the limitations on vinyl and that the noise from the record playing would easily negate any benefit from the reg.

Seeing Hugh's headphone amp, I thought I'd have another look. The performance of this reg is stunning, actually I can't see a better purpose for it than a high fidelity HP amp.
I have started a board layout to give this a home in MY new headphone amp.
