New SR Orange fuse ...

My guess is........nothing.

Years ago Shunyata offered a solid copper slug to use in place of a fuse. I wonder how that compares?
BTW, I have all the SR blue fuses, before that blacks, before that reds, before that others.

Ozzy ...

You really should jump on these Orange fuses. Once broken in they are miles ahead of the SR fuses that came before them ... even the Blues.

As the SR Orange fuses have been breaking in, I’ve been taking notes. Here’s some of my observations:

Compared to the SR Blue fuses ... 

1. A further relaxation in the presentation. Less HiFi and more realism.

2. Clarity - less grain. I thought I had this one whipped, but who knew?

3. Expanded soundstage. Instruments and performers are more well placed within the stage.

4. More articulation in vocals. More organically human. The great song stylists have me hanging on every word, and really getting into the lyrics.

5. Improved dynamics. Drums of every stripe have more impact and realism.

6. More body to everything. More meat on the bones.

7. Improved tonal accuracy. Violins, cellos, guitars, and pianos get five stars for sure.

8. The volume level can be set lower while getting the same loudness level as before making the switch from the SR Blue fuses to the SR Orange fuses.

9. There is an added warmth in the mid-bass that is very attractive and involving. Not overly done ... but just right. Everything is system dependent of course, and in my system, using ARC gear, this little bit of added warmth is a real improvement.

Highly recommended.

Do you have to buy the black and blue fuses first, or can you go straight to orange?
I wish I could justify the expense on a fuse... but I can't. However, wrapping masking tape around the glass part of an ordinary fuse yields a good improvement.
