Several years ago I bought a Nakamichi cassette deck and I now have three. My listening sessions on the cassette players are usually longer than my CD sessions, FWIW. I'm telling you this because as much as I think cassettes sound great, I'm usually told that reel to reel is the closest thing to the original source. Just be sure that you have a competent tech who can go through your deck and align the heads and change belts. Also, be sure you can get high quality tapes at a reasonable cost. As Schubert said, if your dad left this deck for you, how can you not invest the time and money into this heirloom?
