I had never checked the rails with a multimeter before yesterday, didn't realize that software was that far off. I checked the rails on my TT Silent Purepower 560W with a multimeter and here's what I came up with.
Idle- 3.41, 5.05, 12.10
Load- 3.39, 5.06, 11.99
Isn't that something? I just thought that it was pretty impressive.
