try getting an older 2 channel recevier from the 80s , it really woke up my chorus 2. I have an onkyo 717 that we tried on my sons belles and it sounded terrible, he had a denon and that sounded bad too. He had a friend come over with a old sony integrated amp and the belles came alive so he bought the amp from his friend. For Christmas my son got me a pioneer sx 780 that he had somebody go thru and I hooked that up to an old pair of advents unti he can finish my chorus 2s and they sound awsome, I cant wait until he finishes the chorus s, all thats left is the grilles then I can bring them home.
