Cafe Walter Audio is a small business in Seattle, Washington. It is a way for me to engage in my passion for designing, building, and using audio equipment. I’ve been involved in audio for over 30 years, with high points including managing sound reinforcement for several regional multi-stage festivals and constructing four radio stations from the ground up. Clients include Teatro ZinZanniCafé Nordo, and KEXP-FM.

Additionally, Cafe Walter Audio manufactures music and hi-fi equipment such as the HA-1 headphone practice amplifier and the PZP-1 piezo pickup buffer.
