Design Philosophy With my pro audio background in the recording studio and live concert mixing, I wanted to build an amp that allowed me to hear music the way I know it should sound. I wanted it to be easy to use, reliable and with plenty of power to drive the speakers. In short, I wanted power without compromising the music. 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. That??s 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. It??s safe, consistent and the settings are always perfect so you can enjoy your music. What is Bia? In Greek mythology, Bia is the Titan Goddess of force and power. Key Features Plenty of power to drive your speakers Pure Class A power is fast and musical 4, 8 & 16 Ohm taps gives you options for your speaker preference Dual Mono gives you less cross talk and better stereo imaging No adjustments with Auto Bias. Its safe, consistent and settings are always perfect Provides enough gain for most standard preamps and accommodate most speakers Choice of either Single Ended RCA or Balanced XLR to suit your needs or cable preferences Transformer balanced XLR input offers true noise rejection and isolation from the preamp Left and Right ground switches on the XLR balanced inputs to help eliminate ground hums No Negative Feedback provides for virtually no compression to your music Custom Toroid provides lower noise with plenty of available power Global mains power supply can work all over the world KT120 compatible Push-Pull circuit design gives you more power Ultra-Linear circuit design provides lower distortion Low noise levels allow really dark black quiet musical passages Non inverting polarity retains the same phase as the input (so your trumpets blow and don??t suck) Gold pin sockets are more reliable because gold doesn??t??t oxidize when it heat cycles Matched quad output tubes retain the stereo balance It??s ready to enjoy with 50 hours of factory burn in on all circuits and vacuum tubes.
