The Adrenalin amplifier represents the point of arrival of the INPOL (Inseguitore a Pompa Lineare, Line Pump Tracker) concept. The monoblock delivers 200W of power on a load of 8 Ohm and use a layout tested many times by Pathos. In fact is a balanced stage, which means that each amplifier is made of two power stages connected with INPOL configuration, intrinsically functioning in class A.

We like to underscore that an INPOL stage can work only in class A. It is neither a push-pull circuit (where it is possible to choose how deep to polarize the final stage during the phase of design), nor a single-ended stage; considering the presence of reactive element that works in symbiosis with an active device (in this case a group of mosfet connected to common drain). INPOL represents an alternative between the two configurations; hence, this topology created and patented by Pathos has properly gained by now its place in the Gotha of Hi-End.

The peculiar characteristic of the unit is that of a tube amplifier with very sensitive and refined timbre combined with amazing output capacity. It seems that Pathos designers are technicians have archived the target of obtaining the "mirage of an iron fist in a velvet glove."
