The New Synergistic Research Purple Fuses

willgolf - No problem with directionality. My fuses are actually vertical in my components not horizontal. The OEM fuses have small arrows on the top. I followed the same orientation. If your fuses are horizontal I would think that your orientation would be to insert the fuse with the SR writing facing inward >>> I know the the Anthem STR Integrated amplifier has a horizontal fuse. Arcam88 deployed his Orange fuse horizontally >>> with the SR facing inward.

I did reverse mine after 150 hours and in my opinion the fuses are directional. The sonic presentation was muted and the soundstage collapsed. A quick reversal and the the magic was back.

In any case I’ve had many conversations with Chris VenHaus of VH Audio and he states there is really no wrong orientation. It’s up to the listener to determine what sounds best. In any system it was important to get a good burn in before changing the orientation.

Leaving the components on continuously helps the burn in process. The AC is continuously cycling. However good long listening sessions are the best way to discover your systems sonic signature changes.

All the best

I have all orange fuses in both systems. i took my ohm meter and found which side of the horizontal fuse holder went to the incoming power from the cord. I placed the "S" side of the fuse there. Is this what others have done for directional correctness? 

I didn't use an ohm meter. Sounds like you've deployed them properly. Burn them in for 150-60 hours and reverse their direction. You should hear a sonic difference. 

I've moved over to the SR Purple fuses. 

Best of luck

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?

@rmpribeiro Just leave your equipment switched on. No need to play anything.
