Atma-Sphere Atma-Sphere S-30

High End OTL Tube Amplifier, 2 x 30 Watts, Mk 3.3

The S-30 is the unchallenged state-of-the-art in low power vacuum tube amplifiers. With its simplicity of operation, small footprint, and all the features of our larger amps, the S-30 represents the high-water mark of compact OTL design. 

For those who seek the ultimate in amplifier design the S-30 gives you the same precision and sound quality for which Atma-Sphere is known. Featuring automatic bias and a large VU meter, operation is elegantly simple. 

The S-30 utilises decades-proven patented handwired circuitry so is stable with any load. It performs and sounds better than any single-ended amplifier; a nice choice for a loudspeaker that does not need high power. Its fully-balanced design and proven class-A triode operation makes the S-30 the ideal choice for the discerning audiophile.
