Description
Supex 900 Super and its dedicated Supex SDT-77 Step-Up. The cartridge is in mint condition, having been entirely restored with original parts (damper and aluminum cantilever with Vital stylus) by Daniele Montebovi's renowned Cartridgelab laboratory.
It is an extraordinary cartridge, developed and manufactured in Japan by Yoshiaki Sugano, a revered figure in the audio engineering world who later founded the prestigious Koetsu.
This cartridge is therefore the forerunner of all subsequent Koetsu cartridges.
It only underwent a 50-hour break-in period. Everything is perfect. And considering the perfect restoration, it can be considered a new cartridge.
