Pathos InPol Ear Reference Headphone Amplifier
“Insanely great.”
A class-A hybrid with two Electro-Harmonix 6922's and Pathos' InPol circuit
InPol Ear is a pure class-A integrated headphone amplifier, with a fully balanced latest generation double InPol. It features two balanced and one unbalanced output and allows the addition of the HiDac Mk2 converter. The balanced output offers 10 W into 16 ohm, and the single-ended, 6 W into 16 ohm.
InPol (Inseguitore Pompa Lineare - Linear Pump Follower) is a Pathos patented system that allows for much greater output in pure Class A. This fully balanced circuit design uses a single solid-state component in follower configuration, with a high-current gain and voltage gain together. Think of the directness of SET with the control and damping of solid-state. InPol technology allows the tube input stage to effectively drive your speakers with no further amplification.
An optional HiDac Mk2 converter offers a high-quality onboard DAC with digital inputs.
The InPol Ear has Pathos' eye-catching (and highly effective) logo-shaped heatsinks, and comes in a range of center panel options.
