Looking around, I see that Origin Live have a 'Cartridge Enabler' that decouples the cart from the headshell...£25.
That also has rave reviews...
“I would never have imagined that such a tiny piece of material could – albeit placed in a critical position – make so much difference”

“Origin Live’s Enabler is highly effective and makes a great deal of sense as a simple fit-and-forget upgrade”
Hi Fi Choice
“I couldn’t believe all the detail, clarity and timbre that I was hearing for the first time. Like looking at a street lamp in the dark with smudged specs, then cleaning them with a microfibre cloth and seeing the difference!
