Pathos InPol Heritage MkII Tube Hybrid Integrated Amplifier

A pure class-A ECC803S input stage pairs with Pathos’ double INPOL technology offering high output with exceptional damping

With the Mk II version of this celebrated amp, Pathos has doubled the power section turning it into a dual mono unit. Another heat sink increases the radiating surface and allows better placement of the MOSFETs. Thanks to these improvements, Pathos got better dynamics out of the amp, especially in the low frequencies.

Think of the directness of SET with the control and damping of solid state. Pathos’ patented and unique InPol technology allows the tube input stage to effectively drive your speakers with no further amplification. A dual InPol circuit delivers the low impedance and high current needed for a high damping factor, allowing for immense control over your loudspeaker drivers.

InPol (Inseguitore Pompa Lineare or 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 both a high current and high voltage gain.
