Funk Firm Achromat II 3mm Coloured
In 2009 Achromat came top in a mat comparison in HiFi Choice and then went on to win the Gold Award for Accessory against all comers.
Achromat is the natural progression from the original acrylic interface invented by Arthur Khoubesserian back in 1979. Refining the theory he subsequently launched Achromat in 2005.
Ongoing refinements in composition and application means that Achromats are now more universal and better than ever.
Difference compared to 5mm:
Rega arms for example have no VTA capability or are very awkward to adjust. They are also commonly found on decks with felt mats about 3mm thick.
A special version of Achromat has been made available as a convenient way to get most of the benefits that Achromat has to offer.
Another reason is for those decks with short spindles and a clamp; the 5mm would cause problems.
