XA160

Overview

The XA 160 mono block amplifier is a smaller and more physically manageable implementation of the XA 200. It delivers 160 watts into an 8-ohm load, and like the XA 200, cannot be induced to provide additional power under any operating circumstances.

The emphasis of all the amplifiers in this new series is to accentuate performance over power. Characteristics of this series include the warm midrange and sweet top end of the Aleph product, combined with the extreme dynamic range and definitive bass control of the X series amplifiers.

Supersymmetry, the patented circuit topology that is the cornerstone of the X-series, appears again in this new series of amplification, adding dynamic range, bass authority and control, and accurate detailing in support of the lush Class A output stage electronics. The XA 160 is built in the same chassis as the Pass X600 and X350, and presents form and function in a striking balance.

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.
