Describing a professional studio remaster your cassettes as “costly” has got to be one the hugest understatements I’ve seen on Fluther.
Besides, sonically… there’s very little to master when coming from a cassette. The fidelity it really low to start with, especially if the cassettes have have been played for 15–20 years. That’s one of the biggest downsides of analog. Natural decay. And in this case, demagnetization.
