Static from Aesthetix phono stage when tt not on

I have a Rockport Serius II and Aesthetix IO Signature which are connected by a modest ground. Each outlet is dedicated and the audio service has a isolated ground to two ground bars.

I got the tt up and running with new audiophile vinyl and the sound was black in background, clear with high impact and dynamics and plenty of detail.

Everything seemed great for the first round. I weighed the stylus pressura and brought it within tolerance. There was NO STATIC in the music or when the music was not playing.

Today after running the Aesthetix for a day and after playing about 10 lp's there was static building up even when the TT was turned off.

I really don't know where to look for this one.

Is it the phono stage? The 25' Jena interconnects laying on the floor? The TT?

It does not appear to be the Tenor's as they have no noise in other channels.

Thoughts on the problem and identification pattern appreciated.

Hi,
Looks like by having 2 ground bar, you created a ground loop. Try to use single ground for audio gear.

Using a silver-based ground wire helps tremendously, especially if you can find an 8ga silver litz wire for ground.

Silver plated ground bar helps further. Common Home Depot ground bar may be zinc plated and
have dielectric effect.
