New Synergistic Master Fuse

Add that to the fact that the audio signal does not go through the AC line fuse.

Yes, the audio signal goes through the fuse.  I mean where else?  You don't know what you're talking about.

this is terrible news ozzy, I was hoping not to try one on my new DAC...

I've bought Blue and Orange Synergistic Research fuses over the years and in each case they positively improved sound quality. 

This new fuse is likely to be good tweak but is much too expensive for my budget. But I would recommend for those who can afford one to try it. 100% 30 day refund is offered. 

After much procrastination went ahead and ordered a SR Master Fuse for my Power Conditioner.

SR recommends putting a Master Fuse in either the DAC or Power Conditioner to begin with. Since the Power Conditioner is the only gear that doesn't have a Purple fuse, thought that was the logical way to go.

Waiting for someone to confirm if putting a Master Fuse in their Streamer or DAC is better.

Great question, Lordmelton.  The only viable place for a Master fuse is in my streamer.  My conditioner has no fuse and my Lyngdforf 3400 does the dac-ing and also has no replaceable fuse.  A purple in my streamer has been amazing, but I can sell it if the Master gives me a nice step up.
