Class A Design
The tubes are always on, so you have power when you need it. Class A is fast and responsive. There is no lag, providing your music more punch, transient response, better dynamic range and transparency.
Circuit Topology
I choose a Class A Ultra-linear, Push-Pull circuit design to deliver the most precise, enjoyable and faithful reproduction possible.
Unsung Hero
The unsung hero of a power amp is its power supply. Thats why my design incorporates a custom Toroid power transformer and a choke-based, dual-mono power supply to deliver all the slam you can handle.
Easy to use
With Auto Bias, you need no adjustments. Its safe, consistent and the settings are always perfect so you can enjoy your music.
What is Bia?
