So your distributor covers return shipping for your customers. In the USA, we pay to ship it back...................... Score 1 for Australia and 0 for USA......................... |

It might be the WiFi router of your wireless phone interference the speaker pics up. It happened to me once and I had to move it. It happens in multiple locations with nothing else plugged in. It happened in my brick wall lined basement at least 10’ from anything but the outlet. IF Big IF the problem is a SMPS, that kind of junk can migrate up / down power lines and radiate thru the air. My Panasonic Plasma TV would render AM Radio unlistenable out to 20' to 25'. Make sure your Mac Mini is unplugged and ANY dimmer or microwave or some OTHER stuff is OFF. Even UnPlug your Router. I'd even go so far as to try at 0200 in the morning when some OTHER interference producing stuff is 'inactive'. Check to make certain your REFRIGERATOR is Off. I find it really wacky to get 2x amps with a near-identical malfunction in the SAME channel of each amp. Brick is not much of an RF blocker. |

The same deal for things like Projectors here. Officially though its probably not the case, but in my experience if you simply ask them, they do it., I have not been turned down yet. Also the actual incurred shipping costs of the Distributors if they use their shipping accounts is something like up to 10x cheaper than a civilian attempting to do it, its ridiculous. |

I’ve been using mine for a couple days now. No buzzing by here.

I find it really wacky to get 2x amps with a near-identical malfunction in the SAME channel of each amp. Brick is not much of an RF blocker. Me too, but what about all my other amps, including my other Emotiva XPA-7 Gen 2 amp? If the amp topology is incredibly susceptible to these issues by design, that is also not a good thing? Also, nobody has answered why they both do it on channel ONE if it is RF, and not any other channels. I will have my replacement today or tomorrow so I will definitely report back, the distro checked it and confirmed it was good. If it DOES make noise for me again, I will just assume it must be my house or something creating an incredibly odd channel 1 specific buzzing noise while the other 12 channels worth of Amps I have are completely silent in the same rack. |

The one channel 'thing' is what drove me nuts. Something effecting ONE channel? of 2 'identical' amps? That's why I first thought interconnect.
But with everything ELSE disconnected but power and headphones?
A real puzzler.
I'd LOVE to be a fly-on-the-wall of EMO service when THOSE guys show up for 'fix'.
