Feedback in AV system

Pretty experienced Audiophile with a feedback issue that has me stumped. Digital sources (cable/ DVD) work fine without hum, but when I switch to analog sources (turntable, CD, I have noticable hum. Have unplugged individual components to isolate but to no avail.

Suggestions on best places to investigate?

I had this problem after redoing my cables. Had redo again because I had power wire too close to each other. I seperated them and it went away. After I went to find it and traced it back to the 2 differant conditioners I use 1 for analog and 1 for HT and if the power cable were too close it caused the noise but only in analog. Both conditioners come from the same power source.
