INPOL2 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 — eas
ily 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 INPOL2 is a unique amplifier in many aspects and its sound quality will simply astound.
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 low current power supply, dedicated to the tubes. 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 independence 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 and is as close to the top-of-the -range InPower and InControl as possible. The musical, rich and warm sound from the tubes is combined with the pace and dynamics of the mosfets. Transparency, presence, the enormous soundstage, absence of listening fatigue, and the capability of reproducing all instruments realistically — true high-fidelity.
