hello to all

scored some older sda reference bookshelf speaks off e-pay. :D the back of the speakers say to only use with an amp that has a "common ground", i'm assuming vs a "floating ground". does anybody know for sure what type carver amps use? :confused: i have an older avr-100 receiver, it says nothing in the owner's manual about it. thanks!
