Classe is a purist. For a two-channel preamp it is quite minimal functionally. Only Classe owners know how nice the Classe products are designed and integrated, especially the Delta line.
I don't know if CP-800 does sound equal to Berkerley or Weiss DAC202, but I am very earger to read a review here. I own Classe, B&W and using a Weiss DAC2 for computer audio now.
