XA100

Overview

XA100

The XA 100 monoblock power amplifier embodies the design technology and refinements of the larger “XA” series amplifiers, including extensions of the patented SuperSymmetry circuit.

The XA 100 has a massive torroidal transformer coupled to a high current DC reservoir. Recognizing that the XA 100’s ability to resolve microdynamics is best experienced with clean power, the extreme low-level resolution of the XA series benefits from a specially designed power supply that significantly reduces and rejects power line borne noise.

The XA 100 monoblock is packaged in an artistically refined variant of the massive chassis previously reserved for the X250 stereo amplifier.

About the Brand

Based in Foresthill, California, USA, Pass Labs was founded by Mr. Nelson Pass, a well known figure in the high end audio community. Although Pass Labs has only been around for a decade, they have collected more awards than many companies who have been around a lot longer. Mr. Pass is known for unique and innovative, as well as practical, circuit designs. Pass' first designs, in the Aleph line, were single-ended pure Class A solid state. The current Pass Labs "X" series amplifiers use a distortion canceling balanced audio signal circuit, and continue to receive critical acclaim. Today Pass Labs makes amplifiers, preamplifier and speakers.
