While Pioneer was riding high with its Exclusive P3 and just before said P3 became the Exclusive P3a to ride even higher, if not reach a 60% high-end market-share in Japan, the rest of us got somewhat lesser units.
Lesser, here, however, doesn't mean units unworthy of that brand's reputation - just not as big, lavish or... expensive.
The most visible trade-off, besides size, weight and price, is the tonearm which was quite different from the simple-but-incredibly-engineered P3's and filled with electronica, automatic functions and a "Dynamic Resonance Absorber" system.
But it is made of Polymer Graphite nevertheless - headshell included.
If the PL-707 lacks some elsewhere when compared to the P3a, it still reaches a s/n ratio of 80dB !
The 707 saw two production runs : one made by "M.PIONEER" (a change from the usual "PNR") and one made by "KHS", the latter being a T-tag seen elsewhere as well...
