From my private collection:Van den Hul MC-10 Special Moving Coil Cartridge Upgrade with New Micro Ridge Diamond and Boron Cantilever.This cartridge has been upgraded by VAS Mr. Steve Leung with Micro Ridge Stylus on Boron Cantilever and Suspension Complete Tune Up, just did an audition and the sound is great, better than its original so much.
This cartridge has only been audition for less then 1 hour.
Van den Hul MC-10 moving coil cartridge retipped with upgrade square shank, low mass, high polish, grain oriented, gem grade ,Micro Ridge diamond, set onto solid 0.28 mm diameter polished boron cantilever. Cosmetically, this cartridge is 100% like new and better because of the massive upgrade cantilever and diamond.
The Micro Ridge is known to be one of the most distortion-free diamonds available, and it is super quiet in the groove as well. Boron cantilevers are known to transmit higher frequency response with greater facility than other materials and lightning quick transient response.Specifications:Stylus shape: New Micro Ridge DiamondCantilever: BoronFrequency range: 5 - 50.000 HzTracking force: 13.5 - 15.0 mNStatic compliance: 28 Micron/mNTracking ability: 70 - 80 MicronOutput voltage: 0.65 mV RMSChannel unbalance: < 0.5 dBChannel separation: > 35 / > 30 dBStylus tip mass: 0.35 MilligramSystem weight: 8.2 GramVertical tracking angle: 22 DegreesLoad impedance: 200 OhmEff tone arm mass: 8 - 12 GramMoving coil resistance: 9 Ohm +/- 10%Original price is $2250.This cartridge comes with wood box, specifications paper, tool and screws.I have sold a lot of cartridges and got a lot of good feedback, please check them out.And please take a look my other items.Thanks!WayneWayne's Audio
