Building Triode, Class A, balanced OTL amplifiers and balanced all-tube preamplifiers for 28 years.
Welcome to the world's oldest high end audio website, home to Atma-Sphere, the world's premiere (and oldest) OTL and triode amplifier manufacturer. Our claim to fame - and what has kept us in business - is that we created the first reliable and practical OTLs; now proven to be some of audio's best performers.
Electronics for those who prefer music.
Our patented Circlotronic® circuitry is simple and elegant: the best path to music, from source to loudspeaker. Balanced Differential Design® is our total design philosophy- a balanced approach to audio.
Handwired with our custom wire, custom resistors, custom capacitors and the ultimate circuitry - the good stuff! Founder Ralph Karsten and his original staff are here to serve you. |
