FUSES, Finally!?


     I have been adamant about avoiding special fuses, because of the lack of empirical studies.  Here is my question:  What would be something not too expensive that would be a good start.  I use three dual mono Audire amps (for Woofs, Mids and Tweets, and Subs, each of the six channel having four fuses.  I would not not want to spend thousands, even if I could, just to experiment.  My heat sinks do unplug, along with the outputs, and I could try just one channel or one amp.  Paul of PS mentioned what they use, and that might eventually be a possibility, but what do you guys (and gals?) think I should do, to just to convince this ageing skeptic?  Also, each channel of my amps has one single, dedicated computer chip that regulates the filling of the 4 26,000 mf caps (per channel), which might make any difference less than a design that allows a flood of electrons into the tank, presuming that might matter.  DanV

NO.. Fire protection, and equipement protection first.. You can get in trouble if you’re not careful.. Usually there is a 2-5 amp slow blow to get a valve amp going and a .5 -1.5 quick blow, for a tube failure..

LOL I’ve bypassed fuses and really seen an improvement too. It usually had to do with low impedance loads like 1-2 ohm loads and BASS drivers.. Me pushing amps for all I could get, before big class Ds..

Can always rely on a fuse thread for some entertainment. WOW guys really?

If you don’t believe fuses can make a difference, great you have eliminated the issue and can move on. That is, PLEASE MOVE ON. Why waste your time belittling others when you know it’s impossible for a fuse to improve the sound.

I have posted this challenge before. It’s FREE: Swap direction of a stock fuse and listen. If you hear no change count yourself lucky and walk away. If you do hear change then try some good quality returnable fuses. Do they make a difference? - - of course they do, everything makes a difference.

For a reference, temporarily replace a fuse with a clean copper tube and listen to the sound then find the fuse that sounds most like no fuse. I am running my power amp with bypassed fuse which sounds better than any fuse I have tried. It’s staying that way.

@oldhvymec, I like your amps. Jim Bongiorno was one of audio’s greats. I still own one of his Son of Ampzilla designs that blew up at a party 20 years ago after somebody spilled the whole bowl of punch over it. I kept the chassis and rebuilt it with a Neurochrome kit. This is the amp I am running fuseless.

I suppose I should add: Don’t try this at home.
lemonhaze  Is that as good as purple haze?  Seriously, why do people here argue about things they "KNOW" to be true?  How anal is that?  I personally would never bypass fuses.  It is asking for trouble.  Otherwise, your answer is great. I will return to my argument concerning power cords, as it relate to fuses:  What kind of a crappy designer would spend thousands, or more, designing an amp and use crap fuses and power cords that diminish the sound of his accomplishment?  Is he so certain of his design flaws that he wants to hide his accomplishment? 
Purple Haze, was LSD of old.. Hee hee. YUP... Now it is a variety from the "Haze Brothers" and "Super sativas". These were and are REAL things..

As for the fuse bypass.. I’ve never had a problem.. BUT I do take precautions. NO I don’t recommend it, I’ll keep my sonic nuggets to myself...

SS is tough enough to make sound right, without fighting a stupid fuse and a power cord. Talking about James B.. He welded his PC in.. he wanted you to use HIS PC.. Welded, is what they state, not solder a # 12 cable.. Why only a # 12?.. YUP, there is a reason for that too.. It is a certain length too..WHY? All part of the PS design. Smart dude.. Liked Single malt Scotch too.. :-)

To fuse or not to fuse....well I did it, I dipped my audio toe into the fuse pool. Just bought the QSA Light Blue at a mere $71. What could I lose? I know, $71 bucks. So I was going to be the voice of reason. I slipped it in the slot and fired my Raven Audio Nighthawk/Blackhawk modified. I immediately heard an improvement. Placebo? The presentation is calmer, more together, and at times attention grabbing realism. The sound stage seems quieter, deeper, and the tone seems to have more gravitas. My wife said it seems the background is quieter. Then she stayed up an extra hour listening. That rarely ever happens. How? Why? No idea....just better...get one, tell me you hear no improvement. I'll believe you. (I'm very impressionable) (Send back if a worthless experiment)
