Hum Problem with Grado


I recently helped my friend set up his VPI Aries Extended. He is temporarily using an inexpensive Grado ($80 Red?) cartridge but we are hearing significant hum. We grounded the table, which helped, but the hum is still very noticable. Anyone have experience with hum using a Grado and how can we solve this problem? Rest of the system is AR SP16 and VS110 w/ Proac Response 3s. Thanks.

I recently bought my VPI Scout and set it up with a Grado Red just to get me going. I noticed a hum but only after a rather loud listening session where I left the volume way up and went to change a record. I was only a few feet from my speakers and noticed it. Turning the volume way up increases the hum...but I would never even consider listening at those levels. I tried grounding the table to pre-amp, less humm. I switched from my Kimber Hero's to AQ Diamondbacks and got even less hum, but sound was not as good.

Right now I still get an audible hum at high volumes when I am close to the speakers. Normal listening is ok. I'm sure it degrades the sound some and because of this will more than likely change to a new cartridge sooner than I thought.
