That's odd. As I recall Sansui valve amps had excellent sound quality, not great build quality but good enough, and certainly not lots of knobs or buttons. Unfortunately when they transistorised around '70 their quality dropped through the floor.

And, perhaps, the worst output transformers on the planet at the time, competing with, but not quite as bad as Kenwood. That was their downfall on the tube side. The solid-state side, as previously described.

Their OPTs were known for lots of, but flabby bass, and not much, but sibilant treble.
