I picked up a near-mint (in appearance) Sansui AU-517 integrated to go with the TU-717 I've owned for almost 30 years. It's teamed with a pair of Monitor Audio Silver 7s and the sound is unexpectedly good. Clarity and dynamics are there in spades. IMO, for lack of a better term, vintage amps seem to produce music with more 'body' to it. A Sony CDP XA20ES CD player and an Adcom GCD-700 carousel player, both running through an older MSB Gold Link DAC/Powerbase, make CDs sound the best I can recall in a long time. This little system was playing last weekend when two fellows came by to pick up a PS Audio HCA-2/Cary SL-100 combo I was selling. I retired a couple of years ago and have been selling off most of my higher-end (for me) components to beef up my savings. They seemed to be as impressed with the vintage gear's sound as with the newer amp's/preamp's sound through a pair of ADS L-810s (which was pretty sweet). My condo has a very open floor-plan in the area where both of those systems are located, and I think that was a big positive in the equation.
