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.

So your running a USB connection from your computer directly to your amp (which has a built in dac)? NOT GOOD! I advise you Isolate your computer from the amp/dac by using the optical output of the motherboard (hopefully it has one) then into a DIP (Monarchy audio sells these),this allows you to use a XLR or RCA digital out to the amp/dac so that it is now totally isolated from the computer, it is also a jitter reducer and much more! You can read about DIP’s here:

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.
