Reference Amplification
Class-A single-ended triode (SET) circuit design with zero-feedback and 100% tube amplification. Designed for resolution of fine musical details, expansive soundstage presentation, and lush tonal quality.
All Tubes
Only tubes with established reputations for sonic virtue are in this design. Selecting tubes that are now and will continue to be available in the global audio marketplace.
Pure Power
The power supply is a "virtual dual mono block" design. Featuring vacuum tube rectification. Filtering for the Left and Right input stages, including two glow discharge regulator tubes. And separate multi-stage filtering for each Left and Right Channel output tube.
Designed For Headphones
A proprietary output stage accommodates a wide range of headphone impedance from 8 to 600-Ohms, with ease. The Studio Six drives many pairs of headphones with no sacrifice to fidelity. The ideal amp for shared listening sessions.
