Kubala Sosna

Kubala-Sosna Research, LLC is a premium American high-end audio cable manufacturer founded in 2002-2003 by Joe Kubala (engineering graduate with electronics expertise) and Dr. Howard Sosna (oral maxillofacial surgeon and longtime audio industry consultant since 1990). Based in East Hanover, New Jersey, the company employs 11-50 staff members and specializes in designing and manufacturing audiophile-grade analog, digital, speaker, and power cables using their proprietary OptimiZ™ Architecture and RevolutionZ™ Series technologies. After years of systematic cable development and blind testing across solid-state and tube systems, Kubala-Sosna has disrupted the high-end cable market and is now considered one of the premier cable manufacturers globally. Dr. Sosna uniquely balances his 65-hour-per-week dental surgery practice with cable design work at 2am and Sundays, while Joe Kubala handles business operations. In 2021, Howard Sosna retired from active company involvement, planning full retirement from his oral surgery practice by 2024, leaving the company's continued operations under Joe Kubala's leadership with their established reputation for cables that consistently outperform traditional designs in professional audio applications.
