Pass Laboratories is ending the week with a new product in its lineup. The company just started shipping the Xs Preamplifier, a new flagship model.

Designed by Wayne Colburn, the Xs Preamp is made to complement the dual-chassis Xs-300 and Xs-150 Amplifiers. It boasts a frequency response of –3dB at 2Hz and 60kHz, as well as a signal-to-noise ratio of –110dB.

The hook is that this model features two large chassis, which pack in a dual-moaural topology. It has a power supply board with 100,000-microfarad (uF) capacitors and silicon carbide semiconductors, as well as circuit boards with Class-A circuitry and DC-compensation to maintain peak performance.

Making the Xs Preamp even prettier is the high-def display on the front of the unit. This features a 20-character display that can be seen across the room—if you want to see it, that is. It can also be dimmed or turned off completely.

The rear panel is just as nice, with six single-ended, balanced inputs, including a pass-through, a tape loop, and dual-power input connections. It also has two fixed outputs and one variable, both of which are single-ended, balanced and suitable for bi-amping.

Pass Labs is shipping the Xs Preamplifier with its own remote and a $38,000 MSRP.
