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?

Hi David,
If your amplifier is relatively easy on the 300b tube I believe that you’ll be happy with the EML mesh plate. This version of the 300b is a bit more delicate than the standard tubes. I heard them for a few weeks in my amplifier and the sound was beautiful!

My amplifier circuit however puts too much stress on the gentler mesh plate. The solid plate EML XLS is a better fit due to its more robust construction. It sounds exceptionally well in my amplifier. You may have an 300b SET amplifier that can utilize either EML equally well. Let us know your results. Curious as to how the mesh plate compares to the Sophia blue glass tubes. There are many choices available of 300bs. In my experience the 300b is an excellent choice for authentic and very tactile reproduction of voice and instruments.

I am finding your description of the 300B abilities to be quite accurate and attractive. My  amp was designed with the Mesh tube in mind so I will not have to worry about an overstress circuit causing tube failures. 

It will be an education during the next few weeks evaluating these wonderful tubes.

David, 
That's terrific regarding the flexibility of your amplifier towards 300bs. You're in store for much  fun with these various tubes to listen to,

I just talked to Ted Denny and he says this stuff really doesn't do anything and no real research was involved other that some marketing ideas.  He says enjoys reaping a pile of money from the "seekers' who are seemingly born every minute, and apologizes to those who have found his products to be useless…he has issued a resounding "meh."

Hi David,  
I know that you drive your Tersonic speakers with your 45 SET.  Have you tried the 300b amplifer with these speakers?
Thanks, 
Charles,
