Pass Labs Xs Preamp

There are people who do not know that Wayne Colburn has designed the Pass Labs preamplifier products for the last 20 years. Wayne’s modesty has tended to keep him out of the spotlight. When we began development of the Xs power amplifier five years ago, we knew that we would also need a companion piece.

Of course, back then we thought we could have this done in a year or so… Wayne was given carte blanche on the design and an unlimited budget, and lots of time to play with many exotic parts and materials. Naturally the comparison will be made with its predecessor, XP-30 line stage preamp.

The most obvious difference is that the Xs comes in only two chassis, where the XP-30 had at least three chassis, one for supply and control, and one chassis per channel for as many channels as you might reasonably want. The Xs designed solely for two channel operation, and it fits in two (larger) boxes. The volume controls are improved in performance with 0.5 dB steps, expanded dynamic range and lower noise.

Xs Preamp

This large, dual-chassis preamplifier is built in true dual-mono arrangement. Each channel has its own power supply board with over 100,000uf of capacitance for unfettered transient response. Noise levels have been dropped from the already low-noise XP30.

Refined circuit design and layout, new gain-stages with auto-bias and DC compensation all combine for optimal performance. But it all comes down to sound; once you listen to the Xs preamplifier, there is no going back.
