How about a Furman I think (dont feel like getting out of the chair) its a FP or pf 20i 17 outlets some filtered some slow for the amp and all clean $1200 new and run a Furman 70 into it. Its a big toroidal that will last through a surge. It will be spend but clean. The only up grade after those two is a new line in. Yes I know there is a $ issue, sorry. But I love that DAC. And you can unplug the fridge for a couple hours with no problem. as long as the cooler is filled.
