What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Description
On the face of it, all a line-stage has to do is allow you to select between sources and set the system level. Sounds simple? Yet, not only is the quality and performance of the line-stage an absolutely key factor in determining overall system performance, there are fewer contenders for stateof-the-art line-stage honors than in any other product category. Maybe designing the best possible line-stage isn't quite so simple after all.

Pass Labs
XS Phono
45000
/
Released
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.
Pass Labs Class A amplifiers are celebrated for their distinctive sonic character, delivering a rich, full-bodied sound with a notably lush midrange. They imbue a unique sense of "plumpness" and warmth to the music, an intentional coloration that many enthusiasts find highly engaging. The pure Class A design ensures smooth, beautiful sound but comes with the trade-off of generating significant heat, which can warm up a room.

Our Summary
Product Strengths
- A phonostage without compromise in every parameter of sound reproduction
- Easy access via three large front knobs for IMPEDANCE, CAPACITANCE, and GAIN
- Each phono input has its own discrete gain section, as it is a triple dual mono design
- The front panel has a large volume control and a display friendly to read from across the room
- Three pairs of RCA inputs in the back and one pair of RCA and XLR outputs
Product Considerations
- The Pass Labs XS Phono comes in two large chassis
- Pass Labs products are not known for being space saving
- The lack of balanced inputs or an EQ button for early Decca and Columbia pressings might be annoying
- Blue LEDs are built into each change segment of the three large knobs as well as above the push-buttons, though the minimal brightness suggests close proximity operation is expected
Takeaway: The Pass XS Phono exceeds what the reviewer has heard regarding analog playback, with incredible versatility that makes music sound effortless and is worth the investment. If you have multiple turntables, it has musicality at your disposal.
