The Mutech Hayate is a very new Cartridge Launch.
The use of Gold to dampen is off interest, AT was doing this Coating on Boron Cantilevers many years past.
It is also interesting how the Company has flagged up Sound Quality differences being produced from Rhodium in use, not that I have been demo'd to support what I have been informed, but cable producers I know, who put a lot of attention into Connectors have rejected Rhodium as a costing substance many many years ago.
I have avoided Rhodium as I trusted their findings from experiences had.
It also looks like they have gone to an leading industry specialist to supply other metals that will impact on the signal path.
Again AT were using Pure Copper OCC Lead Out Pins in certain cartridge models and now the Hayate has Pure Copper OFC as the Lead Out Pins.
A Friend who has been investigation a selection of Cartridges has informed me, expensive Cart's looked at have a Brass Pin with Gold Plating.
It is nice to see R&D that has been seen as methodology to eke optimisation at other eras in Cartridge Design have found a purpose in the most recent era, what's missing is the Boron with Gold Plating used on the Hayate.
From another forum, I am a follower of a forum member who has used most Japanese Cart' Brands and has models compared from the ranges from Brands.
The Hayabusa was made known to compare very favourably to Brands models costing 3 x the cost of the Hayabusa. I will keep a look out to see if the Hayate is added to comparisons.
