Dedicated circuit

I read a lot of posts on the subject, but my question is I have 6ga feeding a subpanel . My 220 compressor and other circuits are fed from the subpanel.
Should I run my dedicated circuit off the main or would it be ok to pull from the subpanel?
If I run from main it will be close to 100ft of wire, so would be best to use 6ga.
Or, off the subpanel which would be about 40ft, then I would use 10ga from subpanel to dedicated outlet.
Any opinions?
Thanks

If I were to get an answer from @jea48 ,
I would take it as gospel.
Just do a search of his responses over the years and you can see why he is trusted-almost as much as the late Almarg.

@jea48 .
The OP says his line comes from a subpanel that also has the AC compressor.
Would it make sense to simply add another subpanel from the main?
Would that isolate the effects from the AC unit?
(OP-sorry if I am making this more expensive. I only want to see if there is a way to keep the AC from affecting your stereo).

@OP,
I see you also have fluorescent lighting.
I think that as well as the compressor will be another reason to put a separate line to the stereo.
I would like to run a subpanel from my mains, but, due to living in a 100 year old home, there isn't space to add one. Even enlarging the panel has problems.
