If you can’t hear the difference between a stock fuse and an SR Orange fuse, I’d suggest seeking out a different hobby.

If you can, I suggest you seek medical help (just giving back what’s dished out)

I rarely post anything here. I did so this time because I had direct experience on the topic and reported it in a factual and non judgmental fashion. My reward was to be called a lier by one member and told I was in the wrong hobby by another ( I have been in this hobby for 49 years ). I am and always have been in this hobby for the enjoyment of music. I once got into a discussion with Geof Kait on the directionality of fuses and realized

You/we are lucky GK has disappeared (or been banned) he was a real comic piece of work but fitted in well in these types of threads, and his website is really out there https://www.machinadynamica.com/machina5.htm best one is the pebbles.

As for your Maggies I had quite a bit to do with them owning the big Tympanies also, before going on to big ESL’s.

cerberus79A few months ago I purchased a used pair of speakers from another Agon member. To my surprise all the fuses were Orange fuses. I listened to them and then to satisfy my curiosity I replaced them with ordinary buss fuses and could not hear a difference. I did this test with a bunch of friends and neither I or them could hear a difference.


As you stated no difference in sound whether 10cent Bussman fuses were in or $150 SR Orange were in, to yourself or when the guys were around to do the A/B with.

Has the purpose of a fuse been lost ? How it is designed to work ? By design there is no directionality in a fuse. it is simply designed to open in an overcurrent situation. If it was directional in relation to the current passing through it would be a diode


Same thing I say to them, if it’s directional then it’s trying to be a diode, and that NOT good in either direction!

But I can tell your Maggies will sound a touch better with just a piece of copper wire soldered lightly outside of the fuse clamps and no fuses. This makes them vulnerable to an amp blowing and going dc, as you know having electronic knowledge background, but no more so than any other speaker would have no dc protection either.

You could try one of these if you want to retain the protection soldered to the fuse clamps.

As I upgrade my system I’ve yet to purchase a preamp for my newly purchased SS amp and dropped a couple of light blues in a NOS Panasonic SA-HE200 reviver and was very jolted to hear a massive, scary even, upgrade of the sound quality of said receiver.

Just as everyone else said. More quiet, dynamic, larger soundstage, black background etc., and it’s only been a few evenings I’ve had the time to play my little rig!

The fuses are not even burned in yet and the difference in PRAT and is non fatiguing and draws you in to listen is only going to get better. My best least expensive upgrade ever.

I emailed Mike and told him: ’send me two black. I’m gonna take the two light blue and trade up within the 90 day grace period for a yellow’ for my new amp. He got back to me in a timely matter at that. Buy these.
Amazing, isn't it?

Something as simple as a fuse can really leave you gobsmacked to the difference in sound.
Have ordered some 1260. Think I will apply it one connection at a time starting with my yellow fuses coming.
Anyone have experience applying it to a system??
