The designer of The PIP is Owen Jones who studied/worked with Professor Hawksford of Essex University one of who's theories is "Low Fuzzy Distortion" LFD...
I believe LFD is a commercial offshoot of Hawksfords with another guy... (Bewley rings a bell?). The PIP had rave reviews at the time and I reckon it is not much of a presumption that the top LFD phono stages will probably use the same technique...
It scuppers nothing at all! Transconductance amplification is hardly new (though very rarely used in audio) and I can prove that I independently "invented" a transconductance RIAA stage 20 years ago
I have a power amp designed as well that uses the technique to provide the low distortion gain for a zero feedback class A jobby... Vapourware of course
Hey if someone wants to say "I'll buy the first one" I'll start making it exist

I've found the Silbatone C-100 which uses transconductance circuitry. The most recent price for that I can see is €70,000.00. I can't seem to find any mention of LFD using the technique, though information on LFD isn't easy to find full stop.

A possible 3 commercial units then... One made in small quantities, many of which ceased to function it seems, by a no longer trading company donkeys ago... a possible unit from LFD.... and one more which I've never heard of at HOW MUCH!!?? Does it have solid gold casework?
Room for another one then
Oh and did I mention that I've come up with a new technique for servoing the input stage biasing (yeah that's vague.. and all yer going to get) which means I can get rid of all the electrolytic caps in the Paradise? The computer says it works a dream 'n all. Will it work in practice? I'll find out when I make one but I can't think of any reason why not.... famous last words

Brilliant Jez, give it a good servoing
