You have a good system, everything is matched and in about the same league. Nice stuff too. With due respect to everyone else, I would start at the most important link, the speakers. Sell the Vandersteen 1's and get some 2 Ce's at least ($750 used), or else go with some B&W or Magnepan. Your present electronics can drive these and you will get great sound. Next, with due respect to the legendary Ampzilla, I would go with a newer amplifier, perhaps a BAT VK-200 (many for sale here) or an Aragon or such, or perhaps an old Counterpoint with or without mods by altavistaaudio.com? Check it out and get back to us as to what happens.
