Synergistic Red Fuse ...

I installed a SR RED Quantum fuse in my ARC REF-3 preamp a few days ago, replacing an older high end fuse. Uhh ... for a hundred bucks, this little baby is well worth the cost. There was an immediate improvement upon installation, but now that its broken in (yes, no kidding), its quite remarkable. A tightening of the focus, a more solid image, and most important of all for my tastes, a deeper appreciation for the organic sound of the instruments. Damn! ... cellos sound great! Much improved attack on pianos. More humanistic on vocals. Bowed bass goes down forever. Next move? .... I'm doing the entire system with these fuses. One at a time though just to gauge the improvement in each piece of equipment. The REF-75se comes next. I'll report the results as the progression takes place. Stay tuned ...

Any comments from anyone else who has tried these fuses?

Knghifi. Did you place 6.3a 250v fuses in the ref 250 as per Warren Gehl?

Thinking of Synergistic blacks for my ARC Ref 150 and Ref 40 and I see that there are a number of ARC owners who have installed the Blacks in their gear notwithstanding my 2 concerns.
1-The Ref 40 uses a 6amp fuse and the Ref150 uses a 7amp fuse. The Synergistics make neither so I would presumably have to come up short but as close as possible (a 5 and 6.3, or if I'm adventurous, two 6.3s).
2-I believe both fuses are specified as 250v whereas the Synergistics are 500v.
Not an electrical engineer or even an electrician so I do not generally like ignoring manufacturer's choices unless I know that it can cause no harm (e.g. after market power cords).

Ok ok 
My fellow Agoners have convinced me to try the SR Blacks in my Ref 40 and Ref 150. Thanks for the push. Thanks 
I will order a 6.3A sloblo for the pre and a 8.0A  sloblo for the 7. (Thanks Almarg)
They are 6.3 x 32mm in size.

I've heard the UEF panels and they made a clear improvement to the sound.

Oregon Papa:
Ok. Got the blacks. With your amp and pre,which side is up against the rear wall of the unit and which side faces the interior of the unit. I will try your set up first as I have a Ref 150 and a Ref 40.
