Denon HD-M90 - 1988 - US
Denon were only sold in the EU for a short amount of time and in limited outlets. They weren't seen in chain stores, or sold in packs of 10.
Denon are currently also the most consistently expensive blank Cassette brand out there.
Who they were made by varies, some say SKC, some say in house, but regardless, they look good and sound great.
This is their top of the line Type IV - Metal. The manufacturer recommends these to be recorded at around +7db (look at the back of the wrapper).
But they are expensive, and that's just the way it's going to be, unless someone uncovers a warehouse full of them...
