@noromance, if someone has a non-Decapod Decca in their system and thinks it sounds lifeless, something is seriously wrong!
Decca users have for many years packed the space between the top of the metal cartridge body and the underside of the stock plastic mount with modeling clay/Plasticine, to prevent any relative movement between the two. The plastic mount attaches to the cartridge body rather flimsily, allowing a lot of flexing, and not securing the cartridge body to the headshell very well.
I had a Decca Supergold without the Decapod years ago, and now have a London Supergold with the Decapod. I can't attribute the superiority of the Decapod-fitted London over the non-Decapod Decca completely to the Decapod, as John Wright has make significant improvements to the guts of the cartridge. But the Decapod is inexpensive, and I can see no reason why it doesn't make for a more secure coupling of cartridge to arm, surely a good thing!
