Hi Eagleman, it really depends on your price range. I'm running my 2CE Sigs on a Rotel Receiver mostly. However, I've run them on my downstairs system and they are revealing enough to justify a true high end system. So far, I've liked amps from Quicksilver and BEL on them the most. PreAmps from Aesthetix, Theta and PSE. That's not all, it's just my top picks. Hope this helps!
