SR Blue Fuses

Even though some of you who have had no actual experience seem to be in a big hurry to dismiss what b_limo is hearing why are you assuming that he is not an experienced critical listener who is intimately familiar with his own system and is obviously very pleased with the improvements the fuses made ? Don’t you think that it’s awfully dismissive to be telling him that he can’t possibly be hearing the better sound that he is actually hearing ?

Any EE engineer will tell you it’s impossible (snake oil) for a AC fuse to do this, unless it’s aged like this (linked), then that is debatable also.

What you most likely heard was a fuse that’s seen too many turn on cycles, they get fatigued and hardened and build up crusty deposits , like these have with too many turn on cycles.

Same "could" be here in some way, maybe with fuse aging.
Or what he heard when he started this thread at the same time, but it was tone controls of all things that were the problem, after much anxious hair pulling, re his last 2 posts

How many here continually replace their fuses due to on/off cycling?
Not many, I'd guess, as practically all gear made is designed to handle and ameliorate any current rush in, unless it's some DIY POS or something from the '60s, but even equipment from back then still have their original fuses. 

I've never had to replace a fuse due to turn on/off cycling. Never. And when I've swapped out fuses, none have ever exhibited the extreme wear and abuse that Georgie constantly posts. I've made it a point to really take a good look at them and they all look brand new.

Don't fall for his bunk. Trust your ears. It's your hobby and it's not art done by committee. 

I've had gear that really showed the differences in fuses and one that showed nary a difference. Now that I use a AQ Niagara 1200 conditioner, the sound of the fuses have been greatly reduced to the point where I stopped trying them and just use a really good quality, high rupturing fuse that you can get for under $4.00. (ceramic body, filler to kill any arcing, high quality metal caps, etc.)

Bog standard stock fuses that Georgie advocates are made of a witches brew of low to poorly conductive metals that no one in their right mind would use in any wire or cable since they were always thought to be just a preventative against something catastrophic. Since his are blowing on a regular enough basis that he keeps enough around should tell you something.

All the best,

To those not very technical who are considering these snake oil products. Save your money and put it toward a real upgrade of equipment instead.

As it’s always the same old SR persistent shillers, that come back to these threads time and time again to spruik about the "incredible sonic benefits" of installing a >$100 blue or whatever fuse in place of the manufacturers 50cent one.
And then have the hide to say the newer more expensive one when it comes out has even more "incredible benefits" than the $150 one.

Don’t be gullible, and see where this is going. It’s like a malignant cancer. NO Electronic Engineer worth his salt will back this snake oil, and the benefits these shillers claim there are with these snake oil products.

Instead of the SR Blue fuses, I have found putting a 10 gauge solid silver wire in place of the fuse gives excellent PRAT.  Just sayin 😂

What?
Who can afford solid silver wire!
A nice rusty old nail will do nicely......

On a more sort of serious note, I owned a Honda VFR800 a few years back I bought well used with 47k miles on it but it still rode great. One day about 80 miles from home(of course!), it just quit totally.
Spent a few minutes checking basics then removed seat and started looking for fuses, relays etc.
Well guess what! I found the MAIN fuse had been "repaired" with silver foil wrapped around the end caps of the who knows how long ago blown fuse.......
Do NOT try this stunt at home children!

The mid and tweeter in Maggies are fused. The fuses are part of the signal path.  There's a long-held, well-documented practice of removing this fuse bank altogether or at least bridging the fuse holders with a solid piece of silver for improved sound.  Then the audiophile fuses came along to provide another option, and you would be amazed just how much nicer the speakers sound. They are like an extension of nicer speaker cables. I have had HiFi Tuning, Furutech, SR 20, SR Red, SR Black and SR Blue fuses in. Each was a small improvement, with the SR Black and then Blues far and away the largest leaps forward.  There are others out there I have not tried--not schilling for one brand, just ended up there.
 For the AC mains in my amps, subs and CDP, all have improved clarity  with these fuses.  In this position, I compare them to an extension of the audiophile power cable.  The current travels through the fuses, and there must be a level of noise removed by the better fuse using graphene, better fuse body, end caps, etc.  
All I know is what I hear.
