London Reference
The London Reference is the “youngest” cartridge in the London lineup. Unveiled in 2004, it generated a lot of excitement right from the start. The Reference model brings together all the best features. The cartridge body is made of a special aluminum alloy. The coils are wound with the purest copper wire. The stylus features an “ultra low mass fine line” cut.
“The voices…you’d swear they’re in the room. There’s no escaping it. The London
Reference…is the most involving cartridge I’ve ever heard.”, Hi-Fi News, October 2004
