I have one. I bought it when they came out in around 1986. Nice recorder for what it sold for. Has dolby nr. I used it for mixing, ie masters. I had several records made from mixes done on the recorder and they sounded great. But the mastering engineer that I used way back for making the lacquers was exceptional so I don't really don't how much he had to do with it. I do know that whichever version of Dolby it used was not a problem to decode at the record plants.
Unfortunately, I can't find a replacement capstan belt, so I can't use it anymore. I bought a Otari about 5 years ago to use for masters.
