Pathos Aurium Headphone Amplifier

Pathos Aurium Headphone Amplifier   Pathos rose to the challenge of putting its best technology and build quality into a headphone amp that sits comfortably on a desktop. The Aurium is a pure class-A amp that couples a tube stage with a MOSFET power stage. MOSFETs sound like tubes yet have a powerful grip on bass. There are few better ways to combine the magic of tubes with the extended and tight low end of solid-state than the Aurium. The zero-feedback circuit offers all of Pathos' hallmarks: exquisite musicality, airy transparency, punchy dynamics, and total lack of listening fatigue. It is super-accurate and if you want to fine-tune the sound you can tube roll with any of the 6922 family or the 7-volt family such as the 7DJ8. We love solid build quality at Upscale, and the Aurium has a thick aluminum chassis, high-quality components, big transformer, and a knurled volume knob that operates an expensive Burr Brown attenuator. Inside, there are details that make all the difference. For example, the DC filament transformer is shielded from the rest of the sensitive circuitry, lowering the noise floor. On the back of the Aurium is a balance control to ensure your soundstage is dead center. There is also a gain trim setting which allows listeners to set a comfortable range on the volume knob, thus optimizing Aurium for headphones of any sensitivity. Worried about your low-impedance in-ear monitors? Fear not. The Aurium will handle those and pretty much any headphone available. The stock power supply is beefy and gets the job done with aplomb. Upgrade to the Sbooster audiophile power supply to take Aurium to even greater heights. UPGRADE ALERT - You've got to hear the Aurium powered by the Sbooster Audiophile Power Supply. Improved bass slam and definition, more body, ease, and increased air. A huge boost in performance for an already impressive component. Highly recommended. The Pathos Aurium uses the 12-13V Sbooster. It does not take the Ultra upgrade.
