About the Quad PA-One+

A versatile tube headphone amp 

Audiophiles prize vacuum tube amplifiers for their warm, detailed and transparent sound. The British hi-fi company Quad has been working with tubes since 1940, and they've put all their expertise into the PA-One+. It's a versatile component that can serve as a preamp in a two-channel sound system and as a top-notch headphone amplifier for private listening.

Connections

The PA-One+ has inputs for digital and analog sources. The rear panel features a Type B USB port, plus one optical and one coaxial digital input. For analog sources, there's an unbalanced RCA stereo pair and a balanced XLR input. There's a stereo RCA line output on the back for connecting to a power amplifier.

Headphone users have a choice: on the front panel is a standard 1/4" headphone output, plus a 4-pin XLR output for select headphones with XLR4 connectors.
