The New Synergistic Research Purple Fuses

One doubt - to burnin a fuse like the SR Purple is it enough to let it on a dac for exemple with roon feeding it, but with the pre, amp and speakers muted, off, this is to say, with signal just going in the dac where the fuse is, but without signal going out of the dac?

Thank you very much

I upgraded recently to ARC 160M monoblocks, and set them with two Orange fuses, one that I took from my old GS150, and another that was in the Ref6 pre, where is  now a glorious new Purple fuse). I carefully installed  the two fuses with the same direction they were ( along last  two years aprox) on the previous ARC gear, with the S iinside and near the fuse holder top, and the R deep inside the equipment.

Instead of the wow effect I was expecting ( I know very well the benefits of SR fuses namelly the Orange ones), I got somehow a mechanical, 2D image, sterile and harshness effect. I waited for the system to settle down two days, I checked all raised cables, conections, etc. Everything on order. But no improvement 🤔😔

Not very convinced.., I changed both fuses direction. And unexpectedly, WOW, that's it! 😳. Imediate transformation 😜👌. All life returned. Huge and fullfilled soundstage. Focus. Tridimensionality, Dinamics, No more blandness. An almost unbelieveble transformation. 

In conclusion. Direction matters, a lot. And I also suspect that the fuse signal is reversed built on the 160M if we compare it with the GS150 or Ref6 pre at least.
