Unoear - I had a chance to acquire a very nice pair of 16-ohm Valencias about a year ago and foolishly passed on the opportunity. They were being driven with Shindo electronics - the Cortese stereo amp and either the Monbrison or Masseto preamp. Incredibly musical combination! The Cortese is a superb amplifier; it was fantastic with the Valencias and the Shindo pre.
