The Synergistic Research Orange Fuse ... Further thoughts.

Here are my observations after several weeks of burning in the new SR Orange fuses:

1. The sound has a more relaxed presentation. 

2.  Clarity - There is less grain. I thought I had this beat, but evidently not. 

3.  The soundstage has expanded further and instruments and performers are more well-placed inside the stage. The presentation is a lot more three-dimensional. 

4.  More articulation on voices. Vocals are more organically human in nature. While listening to Kevin Mahogany sing "Skylark," I hung on every note and word in the lyrics. Massed voices, like those heard on the Norman Luboff Choir's "But Beautiful" album, are more delineated. The solo instruments are more present than ever before also.

5.  There is a definite improvement in dynamics. Drum solos place the drummer right there in the room with you. Rim shots, bongos, congas and big bass drums are amazing. So are vibes. Cal Tjader and Victor Feldman ... Welcome to the party. 

6.  There has been a further improvement in tonal accuracy. String instruments have taken on a new dimension.  

7.   Among other improvements, there has been a slight amount of welcome warmth added to the mid-bass. The music, as a result, has become more emotionally involving. A little more tube-like in a very nice way.

8.  More meat on the bones overall. Massed strings are beautiful.  Bach's "Air on a G String" ... simply beautiful.  

9.  Lastley, I can set the volume control lower and get the same volume in sound as before.

Overall ... the new Orange fuse is a real winner in my system. 

Highly recommended.

I am also in the process of upgrading fuses in my system from mostly Synergistic Blue to Orange.  There are a couple of questions that I wanted to ask those with experience with these fuses:

- Given the same fuse generation, does a higher Amperage fuse sound fuller and better than a lower Amperage fuse (eg replacing a 500mA fuse with a 2A fuse) ? I assume the higher rated fuse has a thicker filament and could actually result in a better response.

- Is there any way to accelerate the burn-in process? The 200-300 hour burn-in process for the fuse means that I put in 200-300 hours on the very expensive and hard to find tubes that I have in my equipment before I get good sound. And, to compound that, since I will be upgrading my fuses gradually, this means that I will be putting in many hours on the tubes in my DAC, preamp, and amp before the fuses are burned-in. By then, the tubes have aged considerably, which is very concerning.
