1. Anyone on here has upgraded to to the Project K4 from 5E and
noticed any remarkable imporvement.

The Pro-Ject K4 is built by Grado, and the specs and photo look nearly
identical to the Grado Prestige Black/Green. I tried a Prestige Black
on my Debut IIISB (as a replacement for the OM5E) and found it
suffered badly from hum pickup from the motor; it seemed like a decent
cartridge otherwise.

I don't know if the K4 has better shielding than the stock Grado
equivalent, or if the Debut III you've got is less likely to suffer
from this since it doesn't have the speed controller built in, but I
think it might be worth borrowing a cartridge to try first before
buying one.

I ended up buying an Ortofon 510mkII instead, which is what Pro-Ject
ship with the slightly-higher-end Debut SE, and I've been very happy
with it.
