Cassette deck technology has been forgotten: today, no one is capable of producing anything like it , neither for home recording nor portable use. The few new products available on the market are just junk. Even if someone were to invest in creating a high-quality cassette deck today, it would probably be too expensive and therefore unmarketable. The only option is to turn to the past and in fact, the market for vintage decks is very active. I recommend this forum:
