Is a PL 570 a big upgrade from PL 707

[rocknroll1]

I have a 707 that sounds ok but have a chance at a pl 570. Will I hear a big difference?

Technically the Pioneer PL-707 from 1982 is more advance than the Pioneer PL-570 from 1976.

The Pioneer PL-570 with the S tone arm may be open to a wider range of cartridge.

It may also sound better with certain type of cartridges - lower side of mid compliance type.
No, you should not hear a big difference in most cases.
