An underrated receiver. I have the just-below JRS400 -- built like a fortress and with very good quality components. Also, very very wide and heavy. $100 is a little below market value, not a bargain, but a fair price if everything is working.
The "Jupiter and Beyond" (nice line!) styling is not for everyone, but the SEAs equalizer should have been incorporated by other manufacturers, it is very useful and not a toy. I get a kick out of when friends say in disbelief, "what is that!?" They think it is some sort of Yorx combo set-up and blown back by the warm power. This beast can push some solid watts.
Better be local to this because it will cost a bit to ship.
