With the experience of the new InPoL2 MkII and the InPoL Legacy, we modified the InPoL Heritage consequently.

The power supply section doubled, therefore the amplifier is dual mono. We added one heat sink that increases the radiating surface and allows better placement of the MOSFETs.

Thanks to these improvements, we got a better dynamic, most of all on the low frequencies, and we enhanced the power depending on the impedance.

The power remains the same, and so does the aesthetic design. The unit is 14cm longer than the old one, and it is provided with new sealed VU meters and WBT speaker terminals.

Pure Class A

InPoL (Inseguitore Pompa Lineare – Linear Pump Follower) is a system patented by Pathos Acoustics which has enjoyed great success and won many awards.

Inpol devices have a special sonic personality obtainable only by means of this particular circuit design – fully balanced in Class A using a single solid state component in follower configuration, with high current gain and with voltage gain together. The valve amplifier amplifies the input signal voltage and InPol supplies the current to drive the loudspeakers without any further amplification. In this way the signal is entrusted to the valves and becomes a true copy of the original, with all the quality, purity and harmonic content of the original.

This technology allows an increase in the theoretical output in pure Class A of between 25% and 50% together with a low output impedance which is fundamental for the damping factor, and further improved by the double InPol.

InPol Heritage is a fully-balanced pure Class A integrated amplifier using the latest generation double-InPol circuitry.

Its generous 80-watts of InPol power will drive any type of loudspeaker between 4 and 8 Ohms, and create an incredible and emotionally-moving sound-stage.

Thanks to the (optional) HiDac Mk2 board, InPoL Heritage will be able to receive all your music from your PC by USB or from a digital source by S/PDIF.
