With its innovative circuitry and incomparable build quality, Altair II achieves something no other preamp can: the musicality of classic tube preamps with precision and dynamics matched by no other solid-state preamp.

The Hercules II Stereo uses exactly the same circuit as the Hercules II Mono and the original Hercules. The same circuit that inspired a leading reviewer to describe our original Hercules amplifier and Altair preamp as “the most transparent, detailed, and cleanest electronics I’ve heard”.

The performance of the Hercules II Mono is not affected by the speaker, nor by the program material, nor by the listening volume. It delivers the same musical intimacy and emotion with any speaker, with any music, at any volume.
