London Jubilee

The London Jubilee is a cartridge developed by John Wright in 1992. Its body is made of aluminum, and the diamond features an “extended line contact” cut.
A unique design and exceptional sound. Tone, precision, a holographic soundstage, and unlimited dynamics. Few cartridges combine these elements in this way.
As one of the reviewers at HiFi Choice wrote: “Amazing! Incredible! Fantastic! These were the words that sprang to mind when auditioning the London Jubilee…the sheer detail and vividness of the Jubilee bowled me over…brings music to life like no other”
