How many inputs do you really need? For my second system, at my workbench, I really only need one, and that’s to listen to whatever is playing on the main system.
Few people have heard of this product, but for a short time, Adcom made a great little 50WPC integrated amp called the GCA-510. (Good Control Amp ,where’s the F?) It was essentially a GFA-535 with a smaller, lower-voltage power supply, and a passive preamp built in. Apparently, Adcom was going after the UK market, land of small but high-quality integrated amps. (More people sharing walls with neighbors, and we Yanks are so rude with our big amp stacks.)
