New Magnepan 1.7 Owner

Hi guys. I'm the proud owner of really, my first pair of Magneplanar speakers (I only spent a few days with the MG12 and decided to upgrade). I picked up my 1.7's yesterday in the aluminum trim. I will post a review soon.

Anyway, I wanted to ask a few questions about the simplest of upgrades, replacing the tweeter jumpers and fuses.

I need recommendations on fuses and most importantly, where I can purchase them. Also, I don't know much about electronics but I think the value of the fuse is the same as the 1.6 correct? 4A Large Fast Blow?

Also, tweeter jumpers. I have some Audioquest Banana connectors and some Audioquest speaker wire, should I remove the stock jumpers and replace them?

Thanks guys, much appreciated.
