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.

Length of the cable might or might not add to the problem.
Longer cable allows to avoid first reflection adding/modifying shape of original transition (many factors involved). You GH cable might work better because of length or because of better characteristic impedance match. Most likely it is just a better shielding.
