Damn, we should start a Decca Lovers club! I belonged to the Quad Owners club in the 1980’s. Other pre-amps of interest for the cartridge are the K & K and Zesto, the latter having a setting specifically for Londons/Deccas, with resistance and capacitance added.
By the way Ken Kessler of HFN & RR is a Decca/London enthusiast, and also a fan of Croft's work.
