noromance,
Funny you asked this question. Yesterday, I did run my AQ Dragon power cord directly without the SDFB. Just the graphene slug installed.
Now to me, it seemed to be better. But I think it is because I am using an inferior jumper pc in the chain. The AQ Dragon power cord is a fantastic pc in its own right.
I do wish Mark would change the design of the Fuse box to an IEC male on one end so it could be inserted directly into the component, or the other end to have an AC Blade male to plug directly into the wall without having to use a jumper pc.
