Jan Allaerts MC1 Boron Cartridge

The Jan Allaerts MC1 Boron cartridge is one of the finest cartridges ever produced and at the price is an absolute steal. This cartridge outperforms nearly every other cartridge up to $5000. Each cartridge is hand made to order by Mr. Allaerts and as such there is a 1 year waiting time. Is it worth it? Yes.
