VPI Classic hum


Got mine a few weeks ago. Installed it with a high-output Benz Ace H cartridge. Loved the sound but there was a hum when I turned the preamp volume past the 10 o'clock position. Later changed to a Clearaudio Concerto, the hum was quieter, but wouldn't go away no matter what I tried.

Then I read the manual closely, and it said something about using shielded interconnects. So I tried a pair of Rega Couple wires, which are made from Klotz cable, and are shielded.

And you know what, the hum just vanished! Now I'm at peace ...

Just to share with those have hum issues with the Classic. Do share your solutions.

Thanks for the info, I have been following this thread for a long time. I tried to see if I could do a low "cost fix" myself. So far I have spent $500.00 which was my budget for "self fixes." Since I need one of the cartridges that you mentioned (my dealer carries both) I am going to buy it from him and let him do the install. Most likely I will go with the Soundsmith, because it will probably last longer with the way I handle cartridges.
You will really enjoy that soundsmith cartridge. Mine sounds great on the classic 1
Macster, in light of your problems, I think letting your dealer install a new cartridge is a good idea. But before taking it out of his premises, I would ask him to plug it into a system to check it out for hum. Also, I would bring your VPI alignment jig and a digital weight meter to check for yourself that the carty is set up correctly. It should take all of 5 minutes to check alignment and weight. If there's a problem, I would insist the dealer resolve it on the spot. I offer these suggestions because the da*n tables weighs a ton. Why schlepp it around if you can avoid it??
The dealer who BTW is a great guy, immediately started working on the table as soon as I brought it in, he and I did all of the listening through headphones and after trying various things and talking to the guys at VPI, Bruce narrowed it down to the interconnects. Bamm 98% resolved, I won't say 100% until I've lived with it for awhile. He replaced my interconnects with a pair of AQ King Cobra's and now things are very good. Again, I'm going to live this for a bit and try various records before I buy off on this. The hum "appears" to be gone and it is definitely not as pronounced as it was. To be clear, I'm not hearing it. I'm cranking the volume up to 12'clock and nothing.

The downside: I've spent almost $500.00 on cartridges that could have been spent somewhere else. As a matter of fact I'm breaking in the 10X5 right now along with the new ICs.

Thanks to everyone for their help re" Bifwynne and Sbrownw" and also especially Bruce at Stereo Unlimited here in San Diego for patiently working through with me. Next upgrade will be the Zephyr or the AQ Columbias.
If you ran your tonearm/cartridge in balanced mode, you would be able to turn up your volume control to the max and not hear hum. (if indeed you have a grounding grounding issue) As I read trough the above posts, I still think that Bearpaws would eliminate lost of the feedback you are getting (putting the cartridge (just above the record without noise) and touching the record (noise). There seems to be some subsonics coming through the supporting structure, the turntable, the arm that from which you are hearing the harmonics. Also, VPI sells a small weight that can be attached to the head of the arm to change the mass...but I wouldn't readily go there before trying the Bearpaws.
