My Favorite Tweaks, What is yours?

System grounding. 

I like the Purons; but the way they work is weird in my situation. If I already have a Puron plugged and then add a second Puron on the second dedicated line, then I do not like it - as I had stated in the Puron thread.

But I recently found, after a thunderstorm, that if I plug both the Purons within a few seconds, and let them be there for a few minutes AND THEN connect power conditioner, PC power and power up they entire system, then it is a NET positive improvement.

The Gaias (with carpet disks) on the speakers, Isoacoustics ISO-puck mini under all components (except the amp) and the AudioQuest cable risers are other tweaks that I like, which made a positive impact on the audio experience.

I've had many over the years.

Being mostly a vinyl guy, I like a good tt mat and weight. (Not clamp)

Some brand of spring decoupling under components.

Many but the Swiss Digital Fuse Box w/ graphene sluggo stands out.
