Constellation Preamp 1.0

It's remarkable how much of the technology from the Altair II and Performance series Virgo II preamplifiers is preserved in the Inspiration PREAMP 1.0. The core audio circuits are the same. The power supply retains its triple-transformer design. The dual mono design is there, too. The chassis is built from CNC-machined aluminum slabs, crafted in the same metal shop that builds the enclosures for the Reference and Performance series components.


We like to say the Inspiration PREAMP 1.0 is distilled, not diluted. It embodies the essence of our earlier work while retaining the subjective musicality and objective performance that won so much acclaim for our previous preamps.


Of course, the Inspiration PREAMP 1.0's most important characteristic is its sound, which in every way lives up to the reputation established by the Altair II and Virgo II. The slightest subtleties in every musical performance come through unaltered. No conventional balanced-topology preamplifier can equal the detail retrieval, delicacy and musicality the Inspiration PREAMP 1.0 effortlessly achieves. The gear disappears, and all that's left is you and your music.
