The GFA-545 comes from a a family of amplifiers designed to be giant killers.  Amplifiers capable of sound qualities of well known models 2 -3X their price.  The 545 uses multiple high-current discrete output transistors, each capable of handling large amounts of power.  The 545 actually produces considerably more dynamic power that the power measurement suggest.  All of this is possible since the power comes from a tightly regulated, high-current toroidal transformer.

This amp was just acquired locally.  We bench tested it and it sounds excellent.
