I own a Cassete Deck 2 and yes I still record tapes to listen in my car and the quality is very inferior. In the nak at home is fine but I've tried in other home decks with same poor results. In the car the issue is mainly due to the input/output level. To use in the car I have to record with a higher input to be able to have a decent sound level but some care is needed or you'll get sound distortion.
For great home sound from tapes I would say get a Nak but to use in other equipments maybe you can try some other brand, the Sony you mention might be better for wider use.
