LONDON Decca, Tzar DST and similar cartridges


I have always been curious about these phono cartridges and the Stereophile review of the Tzar DST has heightened my interest. When I read about the peculiarities of these cartridges, I am put off from trying them. Can anyone offer persuasive reasons to try them and also provide real practical advice on how to make them work reliably?  Tonearm suggestions? Phono preamp suggestions? Damping recommendations? How badly do they grind out record grooves?  Any other words of advice? Thanks.

@edgware - I bought the FR7 “PW-1” from a Japanese seller on eBay (touching wood I’ve only had positive experiences so far buying like that ...); According to him the “PW” stood for “professional world”, as in Fidelity Research made one offs for radio stations or that sort of thing. I’ve no idea if that’s actually the case or just an educated guess, but that’s what he said.
Sonically it’s really good, I immediately preferred it to the FR 7 and FR7 fz I already had when I got it as it seemed a bit more refined in the high frequency range - more airy on the midrange too.
It must have a lower output (like the fc) as it produces less volume.
If I can figure out how to post a photo I’ll put one on.
@noromance  - love your system ! I have a Radford STA25 just made for those ESL 57s !
it’s not in use but it’s pleasurable just looking at ...
@howardalex Thank you. I had a Radford ST50 long time ago with MO KT88s. Sweet and powerful with 3D imaging. But the big caps dried out and I let it go. My modified EICOs stun me every day with their control, detail, color and lifelike sound on the ESLs.
This is for you Bydlo....to keep you going till your LDR arrives 😃
I run mine at the recommended 1.8Gm (2/3 Static Force, 1/3 Dynamic) with a modicum of Antiskate 🤏

This shows the versatility of the LDR to 'rock' despite the often disruptive interference of Phil Spector....
