I very much agree with sqlsavior's advice to get the Decapod version of the London pickups. It is available for the Gold and Super Gold models, the Jubilee and Reference models not needing the Pod, as they don't suffer from the plastic mounting bracket the Gold and Super Gold (and lesser models) do.
As to arms for the demanding Londons (and earlier Deccas), another approach is to use them with a Townshend Audio Rock turntable, which incorporate a damping "trough" (containing thick silicon fluid) at the front end of the arm mounted on them. The trough provides the damping the Londons benefit from (some consider it mandatory), making a damped arm unnecessary.
In regard to the detail the op desires, the Decca/Londons are legendary at imaging (depth especially), one of their strengths. Another is their astonishing immediacy, presence, dynamics, and plain ol' excitement. Their sound in comparison to most other cartridges is very similar to the sound of direct-to-disk LPs in comparison to LPs made from tape recordings. The cartridge excels at reproducing the percussive element---the attack---of musical instruments. Nothing matches the Decca/Londons at reproducing drums, the sound of a plectrum on acoustics guitar strings, a piano played aggressively. Another strength is their ability at reproducing the "texture" of instruments---the "growl" of a bow being dragged across the strings of a cello, the tip of a drumstick "clicking" on a ride cymbal, the keys of a harpsichord "plucking" it's strings.
