Two suggestions I find very interesting and helpful from George. For one, it’s really better to clean your power by isolating from SMPS devices first than just adding any power conditioning or exotic LPS’s and power cords. Secondly, the battery option does make sense. I am going to try one with a bigger capacity (mAh) though so it lasts longer. While a bit pricier, still beats the boutique LPS brands out there by far, not including the power cords I will be tempted to buy those with.
