Surely the typical high-bias cassette can do better than 10Khz. Now
normal-bias that's a different story. Those have *always* sounded dull
to my ears. But high-bias tapes were always much, much brighter.

Don't know about all high-bias, but I swore by TDK SA-C90 blanks twenty
years ago to the extent I bought them by the case. It may be my imagination,
but when they went from the paper labels (that inevitably peeled off) to the
stamped plastic, the consistent quality I loved went away.

I have program matter on twenty year-old TDK SA-C90s that sound as good
today as they did back then.
