Overview

The newly introduced XA.5 series incorporates all the improvements of the new X.5 series (see below) and also operate pure Class A. The distortion is even lower, the control is even better.

More importantly, the XA.5 amplifiers have tremendously larger output current capacity over their corresponding XA models – more than five times the current – which is more than 25 times the power into very low impedance loads. Very difficult loudspeakers are now very appropriate loads for XA.5’s.

Sonically the result is:

Greater power and control – No matter what your loudspeaker, the X.5 and XA.5 power amplifiers have the power and stability essential to deliver the music without strain. They have the dynamic range to do justice to the 24 bit recordings of the 21st Century and the elegance to retrieve the micro dynamics offered by the most sensitive loudspeakers. This simplicity and power moves easily from total silence to explosive transients with ease and without information loss.

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.
