In 1992 he accepted the chief engineer position at Apogee Sound where he designed the DA Series Class-H digitally controlled amplifier, winning the 1994 TCI Product of the Year Award.
In 2000 he joined Furman Sound, and designed an interface system for Smaart users, and a new power conditioning system.
