Info Wanted on Spectral Cartridges

I think they were were made by Benz. That will mean that they are gonna be very well made. 
There's a guy at Expert Stylus in the UK who refurb cartridges - he knows a lot about Benz Micro cartridges

Dear @ateal: Different Signature models were the latest.

@parrotbee , in those times who participated in the Spectral cartridge design was J.Carr Lyra designer and is Scan-Tech who builded his cartridges and the Spectral an several other cartridges designs out of Lyra or Spectral.


regards and enjoy the MUSIC NOT DISTORTIONS,
