For whatever reason a NAD S300-S500(silver series) combo made the Vandersteen 3a sound better then several more expensive units during a Vandy demo. What a Vandy needs(my opinion) is an aggressive high speed/wide bandwith amp to knock some of the mud and murk out of the midrange of the 1-2 and 3 models. As for a source I have always liked a softer player Accuphase/Meridian over more lively players Ayre/Esoteric. regardless of the speaker. listened to the Arcam-FMJ 23 many times and found it to be a nice/polite and nonoffensive player, not sure if the 33 is as good. Never been a fan of Adcom(brittle/lean and lack of liquidity)despite the power/price ratio. Vintage PS Audio amps are on another level and should work very well with Vandersteen.
