The INPOL2 is constructed as a dual mono, hybrid design 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.
A MOSFET 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 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 INPOL2 is no less than stunning in its detail and involvement. 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 realistically all instruments – all factors giving you the true high fidelity.
