  • X350.5 Amplifier

    X350.5

    The Pass Laboratories ™ X350.5 stereo amplifier embodies the design technology and refinements of the “X” series amplifiers including extensions of the patented Supersymmetry™ circuit. Additionally selected refinements of the XA series amplifiers have been incorporated into the X350.5 to significantly improve this products sonic performance in comparison to it’s immediate predecessor, the Pass Laboratories™ X350.

  • X1000.5

    X1000.5

    The Supersymmetry™ circuit topology was granted a U.S. patent in 1994, and was the result of 19 years of effort by legendary analog designer and company founder Nelson Pass. The amplifier uses highly matched components in a classically simple single ended Class A circuit.
