parasound zDac owners - quick question

Hello,

Im demo'ing a zDac. It has a really obnoxious transformer hum. My 2 zamp v3's have the same hum, so Im afraid this is universal for z products :(

Do any other owners of these have the same experience? I tried it with and without a power conditioner, in different outlets, and with different power cables. I even powered it on in a different room away from other audio equipment to eliminate potential field effects. No help.

Thoughts?

Thanks!

You may have ground current problem at your house.Ground loops are a major cause of noise, hum, and interference in audio, video, and computer systems. Try using balance cables on your system or eliminate the ground to test with an adopter or transformer.
I used z products with no such issues.
