Does anyone know about relevant hardware changes that have been made during the relatively long manufacturing life of the PWT? There are quite a few PWT appearing on the used market as people move toward server based playback. I am looking to purchase a replacement for a Levinson 37 CD transport that died and is not cost effective to repair. I no longer work in the hifi industry and while I would love to purchase a new PWT finances would not allow it. As an engineer, the concept of playback that the PWT uses seems to be the most logical. I don’t want to get in the same situation as the Levinson where a very expensive CD mechanism becomes unobtainable.
