The second chassis allows for a much more sophisticated and lower residual noise power supply. In general, anything that reduces noise in the audio circuit uncovers more inner detail in the recordings. Audio aficionados delight in fine spatial detail in recordings, and lowering noise brings those fine spatial details into sharper relief. What we hear as a result of this more focused presentation is the aforementioned greater sense of space in recordings, but also better delineation of nuances imparted by the performer. The newly designed Pass Labs XP-22 preamplifier incorporates several key enhancements to elevate its performance to a new level of sonic excellence. Utilizing double-shielded low-noise toroidal transformers in an external supply, connected via aviation-grade circular connectors using silver over oxygen-free copper, the XP-22 ensures exceptional power delivery and minimized interference. The dual-mono power supply configuration, featuring two transformers, significantly reduces radiated and mechanical noise, which is crucial for achieving lower THD+N levels. By prioritizing noise reduction, the XP-22 enhances resolution and dynamics, especially at low levels where noise is most noticeable. Additionally, the larger output stage of the XP-22 enables easier and more efficient driving of longer cable runs, while also simplifying the single-ended output circuitry. This design choice not only improves performance but also ensures a more seamless integration into a variety of audio systems. The volume control has been upgraded to a single stage, providing increased range, reduced noise, and enhanced accuracy. Borrowed from the acclaimed XP-30 preamplifier, this volume control enhances the user experience by offering precise and quiet adjustments. The result is a preamplifier that serves as a quieter, more neutral, and highly musical control center for your entire audio system. The Pass Labs XP-22 excels not only in its remarkable measurements but truly stands out sonically, delivering an immersive and engaging listening experience that reveals the finest details in your music collection. Pass Labs and First Watt Pass Labs and First Watt were founded by hi-fi legend Nelson Pass. After co-founding and later selling Threshold Audio, Pass began working out of his Auburn, California, home in the early 1990s to develop prototypes of single-ended Class A amplifier designs under the name Pass Labs. Pass Labs quickly became known for its commercially produced Aleph, X, and XA Series amps, and preamps. Pass later started First Watt as a passion project focusing on low-power amps for a niche audiophile audience. Today, Pass splits his time between the two companies, with production happening in Pass Labs' facility in Foresthill, California, USA. Some of Pass Lab’s most notable products include the HPA-1 Headphone Amplifier, their integrated amp series (featuring the Pass Labs INT-25, Pass Labs INT-60, and the Pass Labs INT-250), the Pass Labs XA25, and more. If you’re looking for a monoblock amplifier, stereo amplifier, integrated amplifier, or headphone amplifier, then Pass Labs has everything you need for your high-end audio.

Who is Nelson Pass? Nelson Pass, the man behind Pass Labs and First Watt, has been designing and building amplifiers for decades. His early passion, however, was speakers; at age 14, he started assembling loudspeakers. As a college student studying physics at the University of California-Davis, he co-founded a speaker company called PMA. He also worked for ESS, where he designed crossovers and enclosures. After college, with his interest having shifted toward amplifiers, Pass co-founded Threshold Electronics (now Threshold Audio). His achievements during the Threshold years include developing the first dynamically biased Class A amplifier circuit; developing a fully cascode audio power amplifier; and developing the STASIS stereo preamplifier and power amplifier. During the 1980s, Pass designed the Adcom GFA-555 amplifier. Later, after selling Threshold, he started Pass Labs in 1991 and First Watt in 1997. Pass holds several patents related to audio circuits. How did Pass Labs make its name? Pass Labs helped popularize solid-state, Class A power amplifiers. Pass Labs' first product, the Aleph 0 amplifier, operated as single-ended Class A up to its 70 watt rating and in push pull Class A at higher wattage. The Aleph series of amplifiers, some of the first solid-state amps that were said to be "tube-like" in sound, operated pure class A and contained internal circuitry using MOSFETs. The Aleph amplifiers had a unique appearance, a cube with heat sinks on all four sides, a solution to the heat generated by the class-A design. This can be attributed primarily to the specific MOSFETs used and the minimum number of gain stages that were implemented in the design. Pass Labs also developed the Super-Symmetry™ ("Su-Sy") circuit, which achieves exceptionally low distortion and noise levels. In 1998, Pass Labs released the X1000, the first amplifier using the patented SuperSymmetric™ topology. The X1000 achieved 1000 watts with high performance, local feedback and only two gain stages: a cascoded differential pair of transistors and a large bank of complementary output followers. This groundbreaking design informed all subsequent Pass Labs amplifiers. What else does Pass Labs make? In 2002, Pass Labs unveiled the first XA amplifiers, combining the X and Aleph topologies into balanced single-ended Class A amplifiers with many of the characteristics of both the X and Aleph series. The current Pass Labs lineup includes Class A amps (XA and Xs Series), Class AB amps (.8 Series), line preamps (Xs and XP Series), phono preamps (Xs and XP Series), integrated amps (INT Series), and one headphone amp. What is the relationship between Pass Labs and First Watt? When he started Pass Labs, Pass did everything out of his home. In 1997, having outgrown the space, Pass Labs moved into commercial space in Foresthill, California. When Pass started First Watt, it was a "kitchen table" venture, with work once again happening in his home. In 2016, with production demands not leaving him enough time to pursue the vast array of yet-to-be-designed amps, Nelson handed the business end of First Watt over to Pass Labs. Pass Labs took over the building of First Watt amplifiers as well as marketing and distribution. There's a synergy between the two operations, in that Pass Labs gets to gather up some of the more interesting First Watt finds and repurpose them as more commercially viable designs. Today, Pass splits his time between First Watt and Pass Laboratories.
