PATHOS INPOL 2 Hybrid Tube Integrated Stereo Amplifier

For sale, we have a beautiful example of the PATHOS INPOL 2 Hybrid Tube Integrated Class A Stereo Amplifier. Handcrafted in Italy, this is a superbly engineered piece of gear. This is a one owner unit that was very well cared for by the original owner. It was paired with a set of Audio Physics Tempo VI speakers. 

On our bench, the unit performed flawlessly. The two 12AX7's and two 12AU7's all tested strong on our Amplitrex AT1000 tube tester. We hooked up the Inpol 2 in our listening area for a week, and we really enjoyed having it. It's a beautiful sounding amplifier. 

The Inpol 2 comes with the original factory remote, and an ac cord. 

We don't have the original box for the amp, however we will package it with great care using a heavy duty box, and polyethylene foam. We spare no expense in materials, and spend the time to pack gear properly. 

From Pathos:

INPOL 2 is the latest creation from Pathos, so-called because in the design Pathos presents the 2nd generation of their proprietary INPOL® technology. It is also a completely balanced dual-mono configuration - easily recognized by the styling. INPOL®, which carries a worldwide patent and gave birth to the multi-award winning products TT and InPower, has undergone advanced evolution. The INPOL 2 is a unique amplifier in many aspects and its sound quality will simply astound.

According to the principles of the INPOL technology, the INPOL2 is constructed as a hybrid with Class A amplification (45watt) and an impressively wide bandwidth in a feedback-free layout. The preamplifier is entirely tube-based, balanced and optimized for feeding the mosfet output stage to maximum effect. Tubes are still the best components for amplifying the signal voltage, in order to preserve the harmonic integrity of the input signal.

A solid state stage is used to provide high current at low impedance, in order to drive any loudspeaker accurately.

The power stage is entirely balanced by the use of two INPOL circuits that are driven in opposite phase to each other, for virtual cancellation of distortion without using any feedback. Large coils are used as energy reserves in order to deliver the current in a fast, effective and precise manner:

Pathos engineers have chosen yet another "unorthodox approach" in the power supply - PHYSICS™ (Pathos Hybrid Stabilised Independent Current Supply). The pre-amplification section is operated by a power supply, dedicated for the tubes, which needs low current. The output stage is fed by a switch mode power supply. The reason for this choice is the Class A output stage's great demand of current at low load impedance as-well as high efficiency and independency of variations on the mains. The two power supplies are completely separated and carefully shielded.

The overall sound of the INPOL 2 is no less than stunning in its detail and involvement and is as close to the top of the range InPower and InControl as possible. The musical, rich and warm sound from the tubes combined with the pace and dynamic from the mosfets results in excellent performance. It is easy to discern that this is an INPOL amplifier due to the absence of listening fatigue combined with transparency, presence, the enormous soundstage and the capability of reproducing all instruments realistically - all the factors of true high fidelity.
