Ive had my cherry 7 system up for a couple days now. Will post pics when I get some more time. I run a onkyo 805 rec. I cannot believe how much cooler it runs. Same settings, same music, volume etc and I am running 20 degrees cooler on top of receiver. I've ran it pretty hard already and I dont really see a need to add on a amp. Depends on if I get other speaks sold and maybe I will. Tech support told me I would not need to add an amp. I do no that this should be my last set of speaks. They sound great, look great and more to come....
