Well, of course it does since everything effects everything else. Questions are: is it audible ; bad ; good ; a lateral change , or what? Mechanical grounding (points, etc) give much different results depending upon system synergy. I chose the rubber footers that I use now because they did no harm and are readily available.
The people at Stillpoints are good people from my experience.
Herbie's goodies work well, too.
Time to dive into the goodie box of forgotten tweaks and see if there is anything in there, eh?
