I have a pair.....superb speakers even at twice what you paid. When I bought mine, I was comparing them to the $800 Paradigm Studio 20. The 20's were overall better speaker, but in some/many ways, I thought the C-3's were better (I thought they sounded less dry)
However, I recently heard Energy's Reference Connoisseur series, and they are noticeably better, and am already thinking of upgrading to the RC10
