100+ Head-Fier
Hi,
I received my new Zero Dac late last week but only got a chance to try it on tuesday as I was away for the weekend. Apart from an issue where the power cord arrived with a broken plug there is something far more troubleing wrong. This thing hums like crazy! i don't mean on the audio - the dac is crystal clear on the audio i tried it with my ultrasones on the headphone stage,mated to my nad amp using the headphone output, through two different stax energizer with a set of electrets and a set of lamdba's the sound is fantastic but the dac physically hums like mad - its actually louder than my music pc and it can be heard though the open headphones i own. The unit physically vibrates and you can feel it when you place your hand on it. Anyone got any ideas what would be causing this and how i would solve it. I emailed the seller - lawrence chan - he's sold a lot of these units to headfi member but i haven't had a reply yet. So while i wait for him to come back to me maybe some of you guys could tell me what would cause this.
BTW i tried two different power cables and plugged the unit into two different wall sockets, this made no difference the unit still hums loudly.
Thanks
