regarding security and best sound enjoyment it is absolut necessary to go for audiophile fuses. I did so for all my audio systems. Now I put in the DSF 4 F Audio residual current fuse in my security board.

it comes with silver coated connectors, massive silver coated conductors and excellent oxygen-less copper.

what is the effect? I did not expect too much but I am surprised that the sound coming from a high niveau gets a bit more balanced, emphasising the bass lines. Would I live in a city or in an industrial area with many influences on current delivery it is definitely a must have to be implemented.
