Pass Labs Xono Phono Preamplifier

Electrical Disclaimer Description


From the legendary Nelson Pass we have one of the most versatile phono stages ever produced. The Pass Labs X-Ono is loaded with features including balanced outputs, adjustable gain from 40dB all the way through to 76dB with multiple increments in between, and enough loading options to keep even the most obsessive analogue enthusiast happy. Whether you're running a high-output moving magnet, a low-output Koetsu, SPU or anything in between, the X-Ono has you covered.

This thing was designed in an era when manufacturers expected owners to experiment and optimise their systems rather than simply plug and play. The result is a phono stage that can be tailored to virtually any cartridge and any system regardless of output level or gain requirements. Build quality is exactly what you would expect from Pass Labs. Heavy, over-engineered and built to a standard rarely seen today. Sonically the X-Ono is quiet, dynamic and transparent while still retaining the natural musical presentation that Nelson Pass designs are known for.

Complete with original factory packaging and the more sought-after black chassis power supply. Finding one complete with the factory boxes is becoming increasingly difficult, making this an excellent opportunity for both the music lover and collector alike. If you can't get your cartridge working properly with an X-Ono, the problem probably isn't the phono stage
