Just a thought. I do not think Monster unit this is a surge protector, or has filtering also does it? For about $150 you can buy a used Powervar hospital lab grade with voltage and line filtering on ebay. I have two Powervars now and a third one for my home theater coming. These filter and offer excellent protection since they were designed for high end sensitive laboratory equipment. These Powervars still sell new for ~$1200 for the model 12 that I have. They are a steal at around $200 used. For my audio system I added an additional level of dedicated line filtering for my two pairs of tube mono block amps into these Powervars. The background noise level dropped down to next to nothing. I have very sensitive 6' tall 2-way horn speakers at over 100dB efficient with 1 Watt at 1 Meter. Just another suggestion is all. John
