Adcom GFA-7805 five-channel power amplifier
For me, the iconic Adcom power amplifier was the GFA-555. As an aspiring audiophile, I was deeply impressed with <A HREF="http://www.stereophile.com/amplificationreviews/678">Tony Cordesman's review</A> in <I>Stereophile</I> in 1985 (Vol.8 No.4). That did it! After years of kit-building and doing it myself, the '555 was the first factory-built amp that I wanted and could afford. Over the years, I changed speakers several times, and even added a fully regulated power supply to the '555, but it never balked. At the end of its tenure at my house, it had been demoted to my third-string backup; today it's making someone else tap his toes.
