This is a reprint of the Stereo Review test done in 1985. It has 2 pages of specs, tests and comments that are crucial to anyone owning this Amplifier! You will love the ability this Amp has when they test it and see what it is capable of! This was an underrated amplifier! One of Adcom's best selling amps of all time, it was followed up by the 555 II a couple years later, but mostly remained the same.
