ATMA-SPHERE S-30MK 3.3 - THE FINEST TRIODE, PURE CLASS A, STEREO VACUUM TUBE AMPLIFIER AT ANY PRICE!
A fast tight bass, warm fluid mids, super smooth highs. Very three dimensional, holographic. Very Musical.
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 audiophiles who seek the ultimate in amplifier design and are realistic about their budget, the S-30 gives you the same precision and sound quality that Atma-Sphere is known and recognized for. Featuring automatic bias and a large VU meter, operation is elegantly simple.
And 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.
