INPOL EAR - Made in Italy (Special Order Only)


Pure Class A Headphone Amplifier and Preamplifier

Overview

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.

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.
