Two brothers (Kasuga) had been working at the Trio/Kenwood factory and splintered away in 1972 to form Kensonic later renamed Accuphase. They wanted to focus a business on the very best sound quality rather than mass production. Their debut models are highly sought after by audiophiles today. Keeping them maintained needs to be regular but is fairly straight forward as they kept their designs engineer friendly. The performance of even their first products surpass a lot of what is produced today.
