The Signature


The Red Signature (Platinum) looks very much like the Red Signature. The similarities however, stop there. The body of the Platinum model is made from aged Rosewood which gives it a darker colour tone. The greatest difference though, is inside.

The coils of the Pro IV are made of 6N copper wire, painstakingly clad with a silver jacket. The magnets are made of the proprietary (and very expensive) Platinum alloy which accounts for the higher price.  

These powerful rare-earth magnets allow the cartridge to respond aptly to even the most subtle movements in the cantilever/stylus assembly resulting in the reproduction of delicate nuances in the music.  

However, output for the Platinum models is lower than the others (0.25mV vs 0.6mV) and a good MC phono-stage is recommended to demonstrate the cartridge’s true capabilities.
