About the B3
The First Watt B3, designed by Nelson Pass, functions as a stereo gain stage featuring one pair of inputs, two level controls, and a high gain/high voltage swing output without negative feedback. It is ideal for use as a front end for power follower amplifiers, bridging, or isolation applications. This buffer/preamp provides voltage gain to drive power stages in First Watt systems, emphasizing simplicity and natural sound characteristic of Pass Labs' Class A philosophy. It is part of the First Watt lineup of low-power, high-quality audio components handmade in the USA.
