New Surround Edge

Diamond has a specific gravity of 3.5—about twice that of beryllium—posing a challenge when paired with film-type edges, which tend to collapse under the weight and exhibit rolling motion. Additionally, conventional edge materials are prone to resonances at specific frequencies, which is another unavoidable issue.

To address these problems, Final developed a new edge using a special polyurethane material. While traditional polyurethane has the drawback of being prone to degradation, this new material overcomes that weakness. It is lightweight yet offers high elasticity and flexibility, successfully resolving the conflicting demands of ease of movement and suppression of unwanted resonance.

ePTFE Shielded Silver-Coated Cable

This cable is a collaborative development with Junkosha, renowned for their work in designing and manufacturing high-speed signal transmission cables used in the “Keicomputer.” The cable employs silver-coated OFC wire, utilising the extensive expertise Junkosha has cultivated under its Junflon® brand. For insulation, it features ePTFE (expanded polytetrafluoroethylene), which offers an even lower dielectric constant than traditional PFA (fluoropolymer), ensuring superior signal integrity.

Note: Due to its tight fit, Final does not recommend frequent cable swapping or connector detachment except in cases of failure or necessary replacement.
