On the evening before the California Audio Show opened, as I gazed at San Francisco International Airport and the beautiful stretch of San Francisco Bay directly in front of the Westin SFO, I thought to myself, "This area is already accustomed to a lot of high-decibel booming and shrieking. But I wonder if it's ready for the sounds that CAS has in store?"
The answer came in the form of what appeared to be a very healthy attendance for Day 1 of the show, and some of the finest sound I've ever heard at an audio show. (The California Audio Show runs through Sunday August 17.)
For its PerfectWave DirectStream D/A processor, featured on our September issue's cover, PS Audio took a different approach. Rather than using the usual off-the-shelf parts, designer Ted Smith used Field-Programmable Gate Array chips (FPGAs) to process DSD data without compromising the integrity of the music. Art Dudley takes the new DAC out for a test drive and returned impressed by what he heard.
