Another excellent stage I have had the pleasure of listening to was a valve hybrid design that Jez built a year or so ago. I believe only one of these was constructed which is a shame as it was really very good (very low self noise too).
Yup spot on. That valve hybrid uses the same method but not in as purist a way as the Paradise or PIP as valve circuitry is limited by not having PNP valves available! An improved but MM version of that hybrid is under construction for a customer as the phono stage part of a complete pre amp at the moment.... which is what is temporarily causing this new phono stage of which I speak to remain vapour ware until the paying job is finished!
