Depends on what the graphene is for. It’s used in my speakers as an anti corrosive on the magnesium drivers. Tossing sheets with a graphene coating on top of amps,dacs and such doesn’t make much sense I don’t see how it would do anything to the sound unless it blocked airflow.
Graphene for audio
A few weeks ago I did an interesting experiment.
I bought a pack of 5pcs of 8"x8" Conductive Graphene Sheets, and I place them above my integrated amp, above my speakers, above my DAC, above my PC and above my power distributor.
I left the Graphene Sheets for over a week, and I was listening to music every day.
I definitely heard something changed over time, but in the end, I’ve got a powerful sound in mid and low frequency, with a significant reduction in the high frequency.
Once I started removing the Graphene Sheets, I immediately noticed that my setup will "breathed" again.
I’m comfortable to say that Graphene "alone" sounds dark and does not improve clarity.
