This is an often asked question. This is my current list of favorites: A. Good out of the box, judging sound quality only, not in order of preference because each has merits:
I just replaced my uber-expensive Magnum Dynalab MD-108 with NOS tubes with a surprisingly enjoyable vintage Sansui TU-919. The Sansui has not been modded and sounds great as-is.
Sansui TU-X1. Haven't heard anything close. A huge rare piece that weighs 30 pounds. Sounded great when bought used. Upgraded by Ken at Stereo Surgeon in CT. Simply incredible sound from live broadcasts off WQXR in NYC (despite their move to the end of the dial). Previously owned Pioneer TX-9100 and modded Sansui 717. Agree with everyone that vintage Sansui crushes any current models.
