The top end of the first “X” mid-end lineup : PS-X6.
The well-remembered one, the PS-X7, was export-only.
Really the very same turntbale but for the carbon-fiber tonearm which the X6 was not graced with.
“Mid-end”, however, is used here to describe a turntable designed and made during what arguably was Sony’s best period. So it may look like a flimsy piece of plastic but it really is NOT.
The only “mid-end” part of the PS-X6 is the tonearm which is unfortunately fixed and isn’t the PUA-1600S found on the PS-8750…
Technically, the PS-X6 is a revamped PS-4300 (march 1976) without pitch controls and a much more compact motor – compact and therefore cheaper.
