Please help me eliminate the hum my digital rig creates

I've noticed a hum coming from my system lately.  It's there whenever amp is powered on, regardless of which input is selected, and hum increases as the volume is turned up.  Today, I isolated the problem to my digital setup-- whenever I disconnect the digital rig from the amp, or remove the SPDIF (Audience Au24-e) between the Bluesound Vault 2 and the Mytek Brooklyn, the hum disappears.

I have upgraded PCs powering both the Vault and the Mytek.  My power conditioning is a cheap belkin single rack unit, but my turntable and phono preamp are both plugged into the same belkin, and there's no noise created there.  I'd appreciate your suggestions on how I can get rid of the noise.  It's driving me a bit batty!

First plug your digital equipment into another wall receptacle and separate digital components from your amp. Secondly are your PC’s shielded on your digital equipment? Even with the C7 plug on your Vault you should use a shielded cable. Not sure what benefit you’re getting out of a cheap conditioner. For an affordable power strip I found this is pretty good; I used it up until I picked up a PS Audio P5. I also used the Supra PC with it which is shielded.
