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.
Because it utilises decades-proven patented handwired circuitry, it is stable with any load and both performs and sounds better than any single-ended amplifier ever produced, let alone conventional push-pull designs. Its fully-balanced design and proven class-A triode operation make the S-30 the ideal choice for the discriminating audiophile.
This unit has all the upgrades: V-caps, Power Supply Boost, Caddock resistors, as well as the mirrored backsplash. Tubes supplied are the original Chinese 6AS7 and 6SN7, all with plenty of life left on them. This amp has seen little use in the last 3 years as the owner has M-60s as well. Cosmetically an 8 out of 10. A new S-30 3.3 with all the upgrades would cost $7,420. This one is $2595.
