My emotiva makes a pop when it goes into standby mode with my 5le's connected. Even worse, when turning on from standby mode it makes an uncomfortably loud 'tick' sound. Have not heard anyone complaining over that yet. I would really like not to send the emo in for repair, as that'll be pretty darn expensive, but it annoys me quite a lot that emotiva send out a unit that seemingly has potential to damage speakers/headphones upon turn off. I'd be okay with it if I could disable the standby mode and just unplug the headphones before turn off, but I suppose I can't. Am a little dissappointed.
EDIT: Well, the power mode switch set to on will have the emo always on. Then I am only ever so slightly dissappointed after all
Contact Emotiva. The mini-X A-100 does come with a 5 Year warranty, maybe theyll pay for shipping both ways for a warranty claim if they think something is wrong with it when you call them.
