The Beacon One is actually 75% of a beacon Two: Output coupling and input circuits as well as the volume circuit are exactly the same. What's changed between the two models is the number of tubes. In fact, both units use a regulated DC filament supply as well.
I love this preamp and have not spent enough time representing it, so I thank you for bringing it up.
Our Beacon One uses a streamlined circuit that was designed to use the tube perfectly, within a set of parameters that will create the most transparent amplification possible. This is a sweet sounding preamp that will interface with any amp.
In fact, I have a combo up for sale: Beacon One + SS-500 soild state amplifier. The Beacon One acts as the ideal interface between amp and source. This hybrid system provides ample current for low efficiency speakers. The combo works perfectly with high efficiency speakers as well due to an extremely low noise output and smooth, linear response.
