Review: They’re still excellent, just a lot more expensive - I haven’t bought blank cassettes for decades. I’ve found the need to duplicate some of my most treasured cassettes and decided to stick with mt old standby, the TDK SA-C90. They’re still top notch, just a LOT more expensive than they were in the 90s!
Review: Perfect, just like the old days - Perfect, just like the old days.The only tapes available at retail stores ( including electronics stores ) in this area are normal bias. The price is reasonable and I will be ordering more very soon.
