The 5, 7 and 10 were great little decks, although there was something about the 10 which I loved (the mc cartridge I suspect).
The SL7 was the one I had most to do with and the sound was accurate but somehow charmless, possibly due to the cartridge supplied, but rest assured, the other P mount carts shouldn't be too bad as they all track at 1.25.
My favourite P mounts were probably the Ortofons, and Shure's P mount versions were pretty good too. I haven't a clue on what's available today I'm afraid. Some of the AT's may be a good listen and there are plenty of styli available still for these.
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
