Graphene spray and ...

Mmeysaroch. Very interesting. I think distortion reduction and the extended
frequency response w/o breakup would be terrific benefits. Luckily there's so much research going on I think we'll get products fairly soon (not the current products that advertise graphene but are probably using plain old graphite ; as there's no explanation about their manufacturing processes-which have to be discussed to be believed).

SR and Magico are investing R&D into graphene because it may have a solid future in our hobby. Graphene fuses provided a tremendous improvement in my system. I'm sure the graphene speakers sound great as well. It's only of matter of time until graphene capacitors hit the market. 

c_avila1, can you describe how your graphene fuses are made?

Non of these little companies can do research on graphene.
When it's available in a form they can use,they will.

Graphene coating can indeed improve properties of many products but on the other hand, it needs to be done professionally. Just spray it sounds like a bad idea. Btw there already are companies that are mass producing graphene. Any company can buy it in very pure form. For example check this.
