Ralph Karsten, founder and CEO of Atma-Sphere, spent an interesting afternoon with SFAS. Atma-Sphere is a small company in Saint Paul, MN that has been making vacuum tube music amplifiers since 1976. Ralph discussed his background, how he got into the hi-fi business, the current and improved state of Class D amps, and the latest product that he's working on - a GaN Class D amplifier. Ralph also discussed at length the benefit of having balanced line systems that meet the AES48 standard.
Thanks to Tony Chipelo for an excellent job of moderating.
