VPI Aries 2 platter is creating hum

Thanks for the responses so far. Have e-mailed VPI. Jeff_jones, will play with the aluminum foil. May I ask what differences you heard with the upgraded platter? For the short time the new platter was on, it appeared to produce clearer detail but wasn't as smooth and musical. Probably something that can be resolved by adjustments.

The original platter is a mixture of stainless, acrylic, cork and lead.

I trust that the new acrylic platter and bearing are better sonically, but think that the white-ish acrylic destroys the look of the table (the new platter looks like the afterthought that it is).

Byfo - Haven't got your email yet. But anyway the answer is that I bought & installed the platter, ring clamp, and a new cartridge all at the same time. Ended up with a better sound but I can't estimate the effect of individual components.

I don't know what would cause hum under those circumstances. Please update if you solve the problem--inquiring minds, etc.

Tried installing platter again. Hum still present. Played around with grounding and foil once again but didn't solve problem. Re-installed my old platter ( the noise floor is absolutely quiet) and will leave. I'm not willing to move components to solve this problem. The sound is good enough.
