Adcom GFA 545 100 WPC Amplifier Into 8 Ohms And 2 Channels. This is a great sounding amp and a good way to enjoy your music without breaking the bank. Audio wise it sounds great. Cosmetically, like most amps, you’ll find some light scratches on the top. You should be able to see them in the pictures. I’ve used this as a second system with an Adcom GTP 500 pre-amp and they sound great together. Of course, you can use whatever pre-amp you want. This will play almost any speaker you might have to darn loud levels, and still sound good.

Very clean Adcom GFA 545ii power amp 100w/ch@8 ohms 150w/ch@4 ohms.Great detail in bass, flawless deep to mid-bass transition. Mids and highs only suffer a tiny bit in comparison to the best $2000 and up designs. Im selling it because I just got some new speakers for my home theater rig, and the 150 w/ch of the GFA 545ii isnt quite enough to wake up the bottom end. The quality is definitely there (in spades), I just need a little more quantity in watts, like at least 300w/ch.

The Adcom GFA 1 was first produced in 1979, Adcoms first high current amplifier. The GFA-1 uses a fan to silently keep the amp cool through all power ranges. This amp sounds as good or better than any $3000 all day. I had an Adcom GFA 555 MKII that I bought in 1985 brand new and this GFA-1 amp sounds just as good as the GFA555MKII. This amp sounds great at lower listening levels and also at higher listening levels. It will move air and yes you will feel like your at a concert, any concert. The amp sounds great running my JBL CF 120 speakers 3 way, 12 woofer 4 mid and 1 done tweeter. 250 watt continuous..
