Aftermarket fuse to tame a bright system?

It took me a while to realize that over damping a room with bass baffles and traps can sometimes boost treble. Duh!

"Ahem...changing the toe-in (or lack thereof) of your speakers can greatly impact treble. Give it a try before lightening the wallet with multi-colored unidirectional fuses."

Believe it or not, there is a very high probability that most people here have played with toe-in,,, extensively.

@jasonbourne71 Maybe fuses make no difference in your system.  In all of my friends systems and mine, fuses make a substantial difference.  With Acme treated fuses, always positive.  With SR fuses, it was a mixed bag (and now 10X more expensive).  I won't touch fuses where the manufacturer specifies not to or where boutique fuses require higher ratings to perform without blowing prematurely.  

I also have some equipment that is fuseless.  Your blanket assertion is wrong just as cabling makes no difference others have stated as fact.  

I use after 25 years of being a beta tester for a cable manufacturer, Blue Jeans Belden digital and XLR cabling pending auditioning higher end cables.  My friends are also changed to Blue Jeans Belden. Inexpensive but impressively neutral and full frequency/dynamic/open and dependably uniform.  Spend the money on the equipment first, then cabling.  As to fuses, $22/$24 Acme fuses are also a huge bargain, unless one's system can't resolve those differences.

@jasonbourne71 What does your audio system consist of and what acoustical/electrical environment is it used in?

I tried silver years ago.  Same issue.  Tried copper.  Same issue others find with copper.  Silver plated copper has same bright edge though to a some what lesser degree and does provide more technical resolution, also to a some what lesser degree. Found solution, also years ago.  Alloys. 

Plating still has two fairly separate conductors even if next to or surrounding one another.  Alloys blend the transmission characteristics into one conductor.  All my glare, bright, irritating over time due to treble were resolved in my two channel system with Purist Audio Design Dominus Luminist cables which use a proprietary gold/silver/copper alloy.  That was years ago when I still had some decent cash flow.  I built a relationship with a Purist Audio dealer and he took good care of me, providing trade-ins and dealer demo at very friendly prices and let  me pay over time. 

Alloys gave me the technical resolution of silver, the treble sparkle without glare AND the warm musicality, natural mid range and bass timbre of copper while resolving all subtle timing issues due to having separate conductors even if bundled together.  More than once I  have been watching a movie with sound through the two channel system, when I was interrupted by someone knocking or pounding on my front door and there is no one there.  It was in the movie.  That has been somewhat reassuring.

Due to financial constraints, not upgrading two channel much in recent years so I've now also gotten into head-fi.  Got some excellent IEMs almost perfect (for me) except for treble, same issues.  Problem solved with Effect Audio Fusion 1 IEM upgrade cable.  Gold, Silver, Copper wires mixed in a very unique cable architecture, again problem solved beautifully.  If only I could have been able to afford the cables with these metals alloyed. 

I do not contend with those who do not think that wires make a difference.  We all hear differently and I am sure they can probably hear nuances I cannot hear. Though if i had the means I know exactly what I want to upgrade, I knew what i had was good enough when after a tweak to my system, I kept forgetting to listen to it because the music kept distracting me.  Let's all just enjoy what we can hear.
