Best tonearm for London Reference Cartridge

I posted in 2014 that I was using a 12" Jelco 750L. I've since upgraded to a 12" Jelco 850L and the improvement is not insubstantial. Highly recommended (entry-level on price) high end tonearm. 

I've been using the Jubilee with a Well-tempered Amadeus turntable and arm.  It is a match made in heaven.  You have to fill the damping cup with goop, but when you do it seems to track faultlessly.  I also had some hum problems but a better set of connecting cables pretty much got rid of them.

I second Rolanda’s post and recommendation of the pairing with a Well Tempered Amadeus turntable/tonearm. I’ve used my WTA with a London Decca Super Gold for several years. As I’ve stated on other occasions “a match made in heaven.” 

I run my London Reference in an FR66s mounted on a Brinkmann Balance.
As presumably with any cartridge it benefitted from using good quality silver tonearm wires (in this case mounted in Arche headshell).
According to John Wright (who makes and services the cartridges) the FR arm is ideal and he uses an FR64.
He recommends a VTF of 1.8 gm (+/- 0.2) with VTA set so that top plate of the cartridge is parallel with the record, although he said there is no absolute and the ear is the best guide. In this regard I found that having the tail of the cartridge a nano-smidgeon lower than the front gave best results.After experimenting I found all works best with no bias setting at all.
As per above (VTF 1.82gm) there are no mistracking issues and it rides warped records as well as anything else I’ve got.
i have various other “high end” mc cartidges and the Decca is by far my favourite. You need to keep records clean and it doesn’t like bad scratches. 

And if you can find any of the various incarnations of the Townshend Audio Rock turntable, it is unusually suited for any and all Deccas and Londons. A Zeta arm mounted on a Rock is a classic combination for the cartridge.
