Pathos InPol2 MKII Integrated Amplifier

InPol 2 MKII

InPoL2 MkII is the evolution of the already well-known InPoL2, a historical exponent of the second generation of InPoL® amplifiers.
The InPoL2 MkII was born from the need to have more power on 4Ω (20% more) and, consequently, more BIAS current. We also wanted to improve the power supply of the power amp.
Last but not least, we wanted to offer the possibility of directly connecting digital sources, thanks to the integration with our HiDac Mk2.

We opted for a return to a linear power supply (transformer – bridge – capacitors). Leaving the power of 45W on 8Ω unchanged, we wanted to give more power on 4Ω: we, therefore, increased the BIAS current, which made larger radiators necessary than in the previous version.
The different choice of power supply allowed us to redesign it in a dual-mono configuration: 2 transformers (one per channel), 2 rectifier bridges (1 per channel), and 4 capacitors (2 per channel).

InPoL devices have a special sonic personality obtainable only through this particular circuit design – fully balanced in Class A. 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 from 25% up to 50% together with a low output impedance which is fundamental for the damping factor, and further improved by the double InPoL.

InPoL2 MkII leaves the previous switching power supply for the traditional linear power supply (transformer – bridge – capacitors) so beloved by audiophiles. Leaving the 45W at 8Ω unchanged, the power at 4Ω has increased: this has increased BIAS current, which has necessitated larger radiators than in the previous version. The power supply was redesigned in a dual-mono configuration: 2 linear, shielded toroidal transformers (one per channel), 2 rectifier bridges (1 per channel), and 4 x 22mF capacitors (2 per channel). With a higher BIAS current the sound, the musicality, the transparency of the InPoL remain, the body and the precision gain, especially in the bass.
