Paul, was your post in response to my comment? I'm pretty sure I understand the purpose of star grounds. I was referring to the Kelvin cap and a few comments by other members when I said that I don't see the point.
"That means a star ground near the input stage, and the biggest signal stages furthest from the star ground."
Well, I don't agree with that at all. By connecting the various grounds in parallel at the center of the star, series grounds - and their potential to create ground loops - are eliminated. With that out of the way, only the voltage drop to each individual stage is of consequence. Because power stages draw the most current and are prone to the greatest drop, they should be positioned closest to the star if possible. Small signal stages will incur almost no voltage drop and can therefore be located farther away.
