Fuses that matter.

"They do more for less than any other tweak I've tried"
Lacee that's my conclusion also after using the Synergistic Research Quantum fuses .
They provided a very noticeable improvement. As long as one observes the proper fuse value markings and the slo -fast blow distinction there's much upside potential with little cost and minimal risk.
Regards,

I'm a little late to the party but my experiences with HiFi tuning fuses in my previous gear (MBL preamp) yielded a noticeable improvement in clarity. I am very bummed out that my non of my current gear has any external fuses I can change.

Oh, found out the Accustic Arts Power 1 mkii integrated I just bought does have a replaceable fuse. Sweet. I will be picking up the Hif-Tuning Supreme and SR Quantum fuses to compare. I will report back in a few weeks.

Update,my friend reports that his AMR fuse for his Rega Elicit amp was the last tweak he feels that he needs to do.

He has been satisfied with his sound many times over the years, and that usually lasts for a few weeks, so if he keeps his system intact, then I would say the AMR or other upgrade fuse maybe the place to start and end in this hobby for some people.

I would suggest that anyone who is starting to tire of the sound of their system, or is looking for a change, that a $20.00 investment in an AMR fuse is the place to start.

If you are still disatisfied, then start on the buy/sell wagon and good luck.

You can't go wrong with the AMR, because they are such good value as a three pack. But the SR20 fuses are just the best imo.

My theory as to why the SR fuses are so directional, is that going by the minimal information available, Synergistic use a high voltage 'Telsa' conditioning process. So they are conditioned in one direction.
