Has anybody used one? I had a Rappaport Pre 1, this dated from the mid/late seventies. It was then, by far the best pre-amp I'd ever heard and I kept many years. One publication described it as the best pre-amp in the world. I would not go that far as there were indoubtedly other great units about, but it certainly impressed me. I have seen negative comment about it's design and it's designer, but I think that was just people with an axe to grind. Geoff.
