Pathos InPol Remix MkII Tube Hybrid Integrated Amplifier

A fully balanced pure class-A integrated amp with Pathos' latest generation double-InPol circuitry and 2 x ElectroHarmonix ECC88.

Italian manufacturer Pathos Acoustics does things right, with ultra-high quality components used in daring circuit designs. All manufacture is done in-house or close to Pathos' factory in Vincenza, Italy.

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.

An optional HiDac Mk2 converter offers a high-quality onboard DAC with digital inputs. 

What is InPol?

When you listen to music, you’re not just hearing notes—you’re experiencing emotion. That’s the promise of Pathos’ revolutionary InPol technology: a design created to deliver all of that emotion.

Traditional amplifier designs force a compromise between the warmth of tubes and the control of solid-state. InPol (short for Inseguitore Pompa Lineare, or Linear Pump Tracker) erases that compromise. It’s a patented, fully balanced, class-A topology where a single triode stage handles all voltage amplification—and maintains 100% of its sonic signature—while the InPol circuit delivers the current gain needed to drive even the most demanding speakers effortlessly.

Features of InPol

1. Pure Class-A with No Distortion
InPol doesn’t dilute or "correct" the tube signal with negative feedback or transistor interference. Instead, it uses a specially designed current amplifier that mirrors the exact character of the tube stage, with zero phase shift or tonal coloration. The result? The harmonic beauty and liquidity of tubes, with the authority and grip of solid state.

2. Emotionally Engaging Sound
There’s a reason Pathos fans describe InPol amps as “addictive.” Music flows with natural presence, dimensionality, and richness—an emotional connection that standard designs just can’t replicate. Voices are human, strings are alive, and the soundstage breathes.

3. Exclusive, Patented Technology
Only Pathos builds amplifiers like this. The InPol circuit is a patented innovation, handcrafted in Italy and unavailable from any other brand. This isn’t another copycat design—it’s a true original for those who want something extraordinary.

4. The Best of Both Worlds
Tube magic meets muscle. The warmth and finesse of tubes drive the musical expression, while the InPol stage delivers the speed, control, and punch that brings complex music to life. It’s a marriage of passion and precision.

5. Class-A with Efficiency
Traditional class-A amps waste enormous energy as heat. InPol’s design cleverly maximizes thermal and electrical efficiency, delivering the full benefits of class-A operation with far fewer compromises—proving you can have purity and performance in one stunning machine.

Italian Design

While the Remix doesn't have the wood front  panel shared by many Pathos products, the Pathos story is best told by a tree. Specifically, the entire padouk tree trunk that's bought by this Italian audio manufacturer, then cut into planks in-house, with the final pieces hand-polished by the son of the Pathos owner himself.

The panel may not contribute to the sound, but this approach says everything about the great sonics you do hear. Having control of entire manufacturing processes from start to finish means that the Pathos TT is the very best amp it can possibly be at its price-point. These are the very best amps Kevin has heard, and it is Pathos that he has picked for his reference system at home.
