DAC drops out when Furnace starts or stops. HELP


Every time my furnace or water heater (gas, power vented) kicks on or off my DAC drops out momentarily. My audio system, furnace and water heater are all on separate dedicated ac lines. My AC panel was updated to a 200 amp service some years back.
I checked all connections from the panel to each device and internally checked all electrical connections in the furnace and water heater, verifying proper hot, neutral and ground.
I checked and tightened all wires in the service entrance panel.
Has this happened to anyone else? If so what did you do to correct it?
Any help will be appreciated.
