Talk:Yamaha K-1000
@ Passat note: No Dolby C with K-1000
Ultimately Dolby C would not have been harmful, (but did not catch on widely). The widespread Dolby B is there, after all. The largest models have the professional dbx, which as far as I know offers noise spacing greater than 90 dB.
The later big models have Dolby C, e.g. there were also more expensive car cassette players with Dolby C, and dbx, e.g. already on the K-1020, or later on the KX-1200. So I can understand the decision for that time.

Dolby C was widely accepted at the time, dbx was not. There were also only a few Yamaha tape decks with dbx: K-720, K-960, K-1000, K-2000, K-1020, KX-1200.
In theory dbx has higher noise margins than Dolby C, but in practice Dolby C is the better system. dbx suffers from noise tails and other artifacts in the version used with cassette decks.
As a tester once wrote about piano recordings with dbx: "Sounds as if the piano tuner had forgotten his sandwich paper in the piano.
And especially when new things are introduced, they are usually built into the top models first. Yamaha didn't do it back then.
Well, at least Yamaha held on to dbx (KX-1200 until 1992), so it wasn't a flash in the pan. - Dolby C was already surpassed or replaced by Dolby S in 1990.
Furthermore, according to Wikipedia, dbx circuits are expensive, so they fit to top models. The frequency response of the K-1000 is similar to CD and high enough, and the drive itself is also capable of something.
You write: "is usually built": As is well known, no rule without exception ;-): there was just decided differently. I find that rather positive. With the successor, and they come at Yamaha quickly and regularly, here the K-1020, are already met your requirements.
