This is the 15 Amp model, but I was told by PS Audio when I inquired about purchasing the 20 Amp model that this one handles 20 Amps, which is why they don't sell the 20 Amp model anymore. In any event, for further info suggest that you contact PS Audio direct with questions. I am selling this for $200 plus shipping ($12 in Continental US only), double boxed, including the - original box. (I paid $400 new). It's about a year old. Price is firm.
