Pass Labs Xs Preamplifier and Xs 300 Pure Class A Monoblock Power Amplifiers



I imagine it is never boring at the Pass Labs offices. They always seem to be trying something new. For the Xs Preamplifier, it was a preamp with the lowest possible distortion. For the Xs 300, it was an amplifier that would have a triode-like midrange, but with the deep bass and treble of solid state. I believe they achieved their goal. These are truly fantastic products and a milestone in design.
