I liked the good vintage stuff just fine until I replaced that recently with a new $80 45w/ch amp with blue-tooth that is efficient, sounds it and is about the size of a pack of cigarettes.
Having heard liked and even sold many classic Sansuis in years past, I am pretty certain it sounds nothing like Sansui in its prime though.
If you need or want the fancy controls, lights, and multiple inputs for less than most anything new that might be considered "mid-fi" or better, then the classic vintage stuff used but fixed up as needed by a reliable tech is the way to go. Just keep in mind buying old electronic gear can be a risky proposition.
