That Sansui cassette deck is a fantastic piece of gear. I had one back in the day, and recently picked up an AIWA F990 ,(?) and Maxells and TDKs recorded on that Sansui back in the 80s sound great all these years later. You can tweak the bias internally on that unit to really work well with Maxells, especially the MX series of metal tapes.
