I assume you used Tesla Apex as phono cable from Aries to phono pre when you got the buzz. Active shielding circuit probably cause that. SR does not recommend its active shielding cable for phono as current going through active shielding circuit is much higher than actual current created by the phono cartridge. That's why SR make non active tricon phono cable (very good cable as well at significantly lower price than Apex).
