The Adrenalin amplifier represents the point of arrival of the InPoL (“Inseguitore a Pompa Lineare” – Linear Pump Tracker) concept. The essence of such apparatus is that of a tube amplifier featuring a very sensitive and refined timbre, combined with a surprisingly and amazing output capacity. It really seems that Pathos designers and technicians achieved their goal: an iron fist concealed in a velvet glove. InPol (Inseguitore Pompa Lineare – Linear Pump Follower) is a system patented by Pathos Acoustics which has enjoyed great success and won many awards.
