Description

The Pathos Aurium was born from a simple challenge Pathos set for itself: take the company’s best amplifier technology and shrink it down to fit on a desktop, without compromising the sound. The result is a headphone amplifier that runs in pure Class A with zero negative feedback, combining a tube pre-stage for voltage gain with a MOSFET power stage for current delivery. MOSFETs bring a tube-like smoothness while adding the tight, controlled bass grip more commonly associated with solid-state amplification — giving the Aurium a rare balance of tube magic and low-end authority.

That zero-feedback design is central to the Aurium’s sound: reviewers and owners consistently describe it as exquisitely musical, transparent, and dynamic, with a total absence of listening fatigue even during long sessions. Because output impedance is adjustable from 16 to 1,000 ohms, the Aurium can be matched precisely to the headphone in use — from ultra-sensitive in-ear monitors to hard-to-drive planar magnetics — while a rear-panel gain trim keeps the front volume knob in a comfortable, usable range regardless of headphone sensitivity. A balance control on the back panel ensures the soundstage stays perfectly centered.

For listeners who like to experiment, the Aurium’s tube stage is roll-able, accepting any tube from the 6922 family or the 7-volt family such as the 7DJ8, allowing fine-tuning of tonal character to taste. The amp ships with a solid stock power supply, and can be upgraded further with an Sbooster audiophile linear power supply for listeners chasing even greater black-background quiet and detail retrieval.

With balanced XLR and multiple single-ended RCA inputs, plus tape in/out connections, the Aurium is equally capable as a standalone headphone amp or as the analog heart of a modest desktop system. It’s a product that proves serious Pathos engineering — and serious Pathos sound — doesn’t require a full-size chassis.
