...says that the key to great bass is not higher pressure but a light cartridge.
I use my Kuzma Air Line for a while now and I tried various cartridges with it. Mainly those, I know very well from Phantom or DaVinci and I am still learning.
The lightest Cartridge I have at the moment is the Zyx UNiverse and it works absolutely excellent on the Kuzma. I am really impressed, there is no big difference - or no loss - to the Phantom or DaVinci. Bass is great on classical records like Stokowski- Hungarian+Roumanian Rhapsody.
I would rate it as a real killer combo.
When I use the heavier ones, there is definately a change in performance. Don't know why (yet).
