I also recommend silver...if you cannot afford the Audio Truth, there are a number of people making silver interconnects and speaker cables that advertise on the internet (ie. "no name brand"). You may want to try one of the ribbon cables like Goertz or Flatline. My experience with them is similar to silver...very aggessive on the top end but without the detail of silver. Also, try to borrow a Bryston power amp either a 3B-ST or a 4B-ST to eliminate the possibility of Classe integrated being the problem.
