brandonhifi,
"I chose the FARAD silver level 2 upgrade over the Sean Jacobs DC4 Arc 6 because it’s 6k cheaper." This hobby is so funny. Sean Jacobs makes two power supplies for the Dave, one at $7K and the other is $10K. Depending on the power cord the end-user has, the cost differential isn’t $3K or $6k, because the Sean Jacobs doesn’t require three power cords. You are correct, if the end-user doesn’t use upgraded power cords.
