All the usual performance metrics - power, distortion, noise, input impedance, damping factor and bandwidth have all been improved in this latest generation. The power supplies are larger, with fast rectifiers gating to larger capacitor banks. The increases in AC line noise worldwide have been addressed with heavier EMI filtering and dramatically quieter power transformers. In addition, through improved biasing regulation, the circuits give much more consistent performance under varying AC line voltages and over a variety of ambient temperatures.

All this is very nice, but only if it improves your listening experience. We listen very carefully and critically to our amplifiers with a wide variety of associated equipment and we take our time with it. Musical performance is most important, and is the basis of our success over the years.

It’s true that we also value the other things. The design and manufacturing decisions have to balance subjective performance against reliability, cost, specs, and ego (in approximately that order). That is why we make more than one amplifier, but all are built with the same commitment to quality.

If you have purchased this amplifier, we thank you for your confidence, and hope that you enjoy it for many years. If you have any questions or comments, or if we can help you with your audio system, pelase don’t hesitate to contact us.

Amplifier, 5XA30.5 specifications

Pass Labs has long been synonymous with high-performance audio amplification, and their 5XA30.5 amplifier is a testament to their commitment to quality and engineering excellence. The 5XA30.5 is an exceptional Class A amplifier designed for audiophiles seeking purity in sound reproduction. One of its standout features is its power output; delivering 30 watts per channel into 8 ohms and a doubled output into 4 ohms, it provides ample power for driving a range of loudspeakers with ease.

One of the key technologies employed in the 5XA30.5 is its Class A circuitry. Unlike other amplification classes that switch on and off to produce sound, Class A amplifiers operate continuously, ensuring that the signal remains uncorrupted. This results in a rich, warm sound that faithfully represents the original recording. The design eliminates crossover distortion, a common issue in other classes of amplification, thus enabling the 5XA30.5 to deliver detailed and smooth audio performance, even at lower volumes.

The amplifier's robust construction further enhances its performance. With a fully balanced differential input stage, the 5XA30.5 minimizes noise and distortion, ensuring that the sound remains crisp and clear. The use of custom-designed output transistors offers superior linearity and thermal stability. Additionally, the generous power supply, equipped with a hefty transformer and ample capacitance, allows the amplifier to handle dynamic peaks without strain, preserving the integrity of the audio signal.

Another notable characteristic of the 5XA30.5 is its elegant design. The aesthetics include a minimalist chassis, machined aluminum front panel, and dual meters that provide real-time performance feedback, allowing audiophiles to observe the amplifier’s operation. Furthermore, it features both single-ended and balanced inputs, offering compatibility with a variety of source components.

Importantly, the 5XA30.5 embodies Pass Labs' philosophy of "the art of amplifier design," resulting in a product that not only performs exceptionally well but also maintains a timeless appeal. Whether for critical listening or enjoying music in a relaxed setting, the Pass Labs 5XA30.5 amplifier promises an unparalleled auditory experience, fulfilling the demands of even the most discerning audiophile. In a landscape where many amplifiers prioritize features over fidelity, the 5XA30.5 remains a beacon of true sound reproductions, demonstrating that exceptional quality and craftsmanship can coexist harmoniously.
