New Synergistic Master Fuse

How does it compare to no fuse at all?

No fuse at all would be a solid wire/jumper.

Fuses, including the expensive audiophile fuses, are always a minor degradation to the sound compared to solid wire. Ignore masturba...92 and he may go away.

I would never buy an amp that I couldn't afford to replace.  And many of these fuses approach the value of the amp they are supposed to protect by destroying themselves.

I'll stick to my approach of no fuse and I'm prepared to replace (or more likely repair) the amp if necessary.
