Having a problem when HVAC system turns on and cuts my system off!


Ok here’s the deal smart Agoners. I have been in this new house with pretty much the same rig with no issues for a year or so. I play music pretty much all day now in our living room space that opens up to the kitchen. Several times throughout the day, not every time, when the HVAC system turns on it will cause my computer server usb connection to the dac to fail. Usually a few seconds after the HVAC turns on the USB signal is lost.....cuts out?

My system is on a dedicated 20 amp line with two levels of conditioning before the dac and computer server. A BPT balanced conditioner feeding two Core Power Technology balanced conditioner/cords to my system. See my virtual system for a better understanding.

I have have to turn off the dac and turn it back on to re-initiate and play music again. My dac is built into my amp just as an FYI. What the heck is going on and what is the fix?

Must be some kind of electrical surge or such that is somehow impacting my direct AC line and system. Strange. Happening more often of late.

I still say your not isolating anything unless you get rid of the USB and go Optical from the computer. All these isolation devices dont help.

Thanks all. I did two things that may have cured the issue. 

- the iFi Micro USB 3 has a grounding switch.  Manual says to defeat it and cut the ground. Well, instead I decided to engage the ground switch 

- I plugged one of my LPS units in a different BPT conditioner outlet

It has not happened since.  Hope this is it!
Well it started up again at 6pm. I will remove the IFi next to see if it stops. 
Stick a voltage meter and see how much it sag. Might want to clean out computer power supply as well. 
Hey Bill. I hope all is well . Do you have a meter that you can put on the outlet that the Golden Gate is plugged into . I would be willing to bet that you are getting a voltage drop when the A/C kicks on.I would bet that the Line Conditioner is the one that causes the drop out .I am guessing that the Lampi is plugged into the conditioner .. right ?
Have you tried plugging the Lampi and or PC directly into the outlet ? Are you running the conditioner off of the dedicated outlet .I would try to bypass the line conditioner. I would bet that it is the culprit...... ????
Good Luck
