Another pathway to "tube" euphoria would be to use a Musical Fidelity (Thank's PhaseCorrect !) X-10D between the Pre-amp and amp. They really do turn the sterile, chalky, Surface of the Sun, bleached sound (of Solid State) into a pleasing and listenable event. They are quite cheap as well. Musical Fidelity does not make them any more, but they pop up (on AudiogoN) from time to time (about 150.00). They use two 6DJ8/6922 tubes and they react well to "tube rolling".In a way, this whole topic is a tad moot at the price range that you are trolling in. 2500.00 for a "used" (or NEW) amplifier is a BUNCH of money (for SS or Tube). No matter what "Solid State" amp that you choose, it will have many positive facets in its favor (and should not have many that will disappoint). There are "always" exceptions to this and I'm sure that we (as Audiophools) have "all" had a "bad experience" or two (or nine). There is no "Gospel" in amp buying.
