Pass Labs Xs Phono

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 Phono

The Xs Phono preamplifier represents an all-out assault on the state-of-art in Vinyl and the most intensive and difficult design effort made at Pass Laboratories.

The final product of this massive effort extracts the utmost performance from a simple topology and operates with the extremely small and delicate signals coming from today’s wide variety of phono cartridges.

The result is music that emerges from a quieter background and blooms into a richer, more precise soundstage
