I would say that of greater significance is noise level, In comparison to even
the most basic interface, cassettes are very noisy (even when using Dolby
systems). As for frequency response, it's a highly variable quantity, and (for
metal tapes) is dependent almost entirely on the *playback* machine, and it's
the head gap width and alignment that is critical - recording can have a much
wider gap size. With a good quality machine you should just about get to 18kHz

For the best possible results, you should fast wind each tape first to loosen
it up, then clean the heads, and while playing a track adjust the head settings
(height as well if it's available) for maximum hf output consistent with
minimum crosstalk. Although tedious, you should do this for each tape.
