I enjoyed my Harman Kardon PM 665 VIXI integrated, Sansui TU717 and AU717 tuner/integrated, and Boston Acoustics A100 for 25+ years. Still got the Bostons, the HK and Sansui are in need of repairs that are prohibitive ...but I must say, after listening to the newer equipment (KEF R100, Focal, Dynaudio along with NAIM power) I miss the friendlier sound of the vintage stuff. My ears aren't that refined that I want to chase the last electron of musical information so hats off to the folks that have the ability to discern such minute differences. I still prefer the older equipment - maybe it's the build quality and heft of the controls, the visual reinforcement of heavy, solid equipment.
