The New Synergistic Research Purple Fuses

My method to find out which direction the fuse should go is to use a mains tester on the fuse holder without the fuse in place. (when possible)

I place the fuse arrow from the hot to the neutral.

Anyone has further comparisons between QSA Yellow and SR Purple?

I have two QSA Yellow (one on a farad lpsu and one on a switch) and contemplating deploying two more, either yellow or sr purple - on my dac and my integrated.

Hi Ted, thanks for your message.

I thought the point of the fuse directionality was that the current should flow in the fuse in a certain way.

I am using a Farad Super 3 LPSU which is proposing your fuses as upgrades, and on the circuit board, there is an arrow for the fuse direction. When tested, the arrow is from hot to neutral so that led me to believe this was the correct way.

So I tested as a reference point and started to listen like this. I also tried to reverse but so far it sounded better this way.

Maybe you can tell us more about directionality?

Thanks,

Thank you for your input
