I have no real personal experience with the problem, but my understanding is that the level of hum can range from almost non-existant to significant depending and it varies from one particular set-up to another. The hum seems to become more pronounced toward the end of the record as, presumably, the cartridge gets closer in proximity to the motor.
Whatever hum might be encountered seems to be fairly low-level and some have reported that they don't find it objectional. I avoided the Grado when I had a P3, but had considered Rega's top cartridge (the "Exact")as it got good reviews and it would be a breeze to install. Heard the "Exact" once, but not in my system, so it would be difficult to say how it performed.
