I own two of the Sony HAPZ1ES and both are dead quiet. One sits on the rack right next to me and I can’t hear any noises coming from the unit at all.  If you bought it used, I would send it back as it isn’t right.

I have talked with the seller and he told the unit was silent , so I'm shipping to united radio for repair and the seller has opted to pay for the repair, instead of me returning which is great and why I like dealing on Audiogon , I had bad issue with Reverb and it was not easy to make a return , looking forward to loading our cd's and placing the sony in our rack 
thanks to all for your input

I have a new unit, received from CA, and I have the hum too. I can't hear it 20ft away as the other member mentioned but it's most definitively there and very irritating considering the price of the unit.
Thankfully I bought it on ebay and it will need to go back. I just hope they have another unit to ship to me.
I have quite a few Sony GS and ES components and all are perfect, some have been going for years and years without a hitch.
