    Yes there was a price recently quoted at 1800 for a built one with the last remaining boards. I wish i had the funds!!!!

    As I mentioned elsewhere the other day I am planning on making an MC only phono stage which uses the same operating principle as the Paradise... which operates in a completely different manner to all other phono stages other than the Pink Triangle "PIP" (to the best of my knowledge no other units using the principle exist anyway). I also independently "invented" the same thing about 20 years ago and built and sold several very good phono stages which are still in use today using the idea.
    It is already designed at computer simulation level and sim results look very good. I intend that it will be a two box unit at around 800-1000 starting price. All circuitry is of my own design and this is not intended to be a "Paradise clone" but a design in it's own right which uses the same operating principle as the Paradise and Pink Triangle PIP.

    I did read that JeZ and intended to comment but got distracted. It's certainly something id like to hear. I'll google the PIP as i hadn't heard of it previously!

    The PIP was a novel design by Pink Triangle and used what, I believe, is called transconductance circuitry. Unfortunately it suffered from a bit of unreliability and they are now very rare.
    -------
    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!

    Jez, if your new design achieves anything like the performance of the Paradise (and I've no reason to believe it won't) then it will be the audio bargain of the century at 800.00-1,000.00

    That's why I'm eager to hear it!

    That's what I'm hoping!

    Edit: Apparently there may be an LFD phono stage with the same technology.
