Synergistic Red Fuse ...

Unfortunately, I have kids still going to college, still a mortgage, and saving for retirement. I really can’t justify spending hundreds of dollars at present on fuses. I've spent tens of thousands to date already to get where I am and I  am currently thrilled to death with the sound of my stuff.  I spend many hours a week listening.   Maybe someday.  Good sound is always a good investment for me.  Can't live without it most likely.

BTW I grew up in Amish country. No joke. Maybe that’s part of my problem. My wife and kid’s tease me about it all the time.

"....BLACK featuring a patent pending UEF coating and Graphene with 8 million times the conductive density of copper... "  Let's make it 5 billion times... 
I've read reports ,  SR20 is manufactured by a german SIBA.  Apparently, when you peel off the fuse a sticker, you can see SIBA logo and even the fuse catalog no.  And the original fuse, SIBA cost 50 cent or so.  Of course, the tunneling process is an added value and makes SR20 a good sounding fuse.

So is the original German fuse Graphene or not?

If not, either the reports are incorrect or there is something shady going on.

^^^ Personally, what I care about is what the products are doing for my audio system. I could care less about any drama and/or the technology. Hey, I'm a salesman not an engineer. Engineers analyze everything to death. They suffer from "analysis paralysis." That's a very good thing. We need them. We wouldn't be flying five miles in the sky at 500 miles per hour in a perfectly safe, pressurized, air conditioned environment without them.  On the other hand, good sales people can make quick decisions without a second thought, being totally satisfied with a 95% success rate. I took a chance on one little fuse, and look where its lead to. 

When someone starts taking to me about ohms, slew rates, capacitors, resistors ... and things like that, my eyes glaze over. I'd rather eat Limburger cheese with anchovies.  All I want is the music.

This is what I know: These fuses, both the SR RED and the SR Black are a revelation. Totally system changing and all for the better. Everything is relative, of course, but in my system, that's the outcome I've experienced.

As a professional salesman, working in commissioned sales for over 50 years, I thrive, and survive, on convincing doubters to buy from me. So here's an offer you can't refuse:  Can you use a 3 amp fuse anywhere in your system? If you want to try an SR RED 3 amp fuse, I can send you the one that I replaced with a SR BLACK fuse.  No charge. Already broken in. Its on me. If you like it, keep it. If you don't like it, pass it on to one of your audio buddies. Or ... you can send it back and I'll gift it to someone else.

Shoot me your email address and we'll go from there. 

Hang in ...

That’s a very nice offer OP and much appreciated. I’ll have to see what’s in what I have. Were I to do this I’d likely start with the DAC, an mhdt Constantine. It has see through plexi glass like casing that is easy to remove as well.

I was an electronics and electronics part salesman for a bit when younger. I let products speak for themselves. Exaggerated claims were not necessary for success. Just know how to help a person find the right solution to their problem. Technical knowledge and expertise helped greatly. The best salesmen were generally the most honest and knowledgeable.  Many fuses were sold to happy customers.   Usually about 50 cents for a pack of three.  Strange nobody ever asked me how they sounded.  I would not have  known what to say.  Simpler times....
