    magic fuse

    http://www.ultrasystem.com/usfeaturedprodsFUSE.html


    Forget about the science. If you were manufacturing expensive gear and this would make a difference, wouldn't you take care of it at the factory?

    I have a ton of modified adcom gear...and have heard about the fuse thing...every tech I have talked to , however, said it is I am sure there is something to it...after all, capacitors, wire, and connectors all sound the same....so why would fuses make any difference I am being sarcastic...if the almost $300 in claritycaps I put in my 3 way dynaudios didn't sound any different than the solens that they replaced, I wouldn't have pissed the money away...but they are WAY smoother,detailed, and more natural sounding. And I tried them in a couple JBL systems before I forked over the dough...Getting off on a tangent again, but I read somewhere where a guy did nothing but change to audiophile type fuses in an old adcom amp...and he was astounded...gonna have to try some...I feel it may be due to the old fuses sitting in the clips for 10-15 years, and the newer clean connection may be 90% of it...I dunno....but I know that pot metal or steel don't make as nice a connection as pure copper or gold...so it goes...
    Why don't manufacturers do it? That's a no brainer....it is too expensive to make the price point...otherwise every upper end speaker would have Claritycaps, Mundorf's, or Auricaps in them...instead of cheap electrolytics and mylars...even very expensive systems will use solens...which don't suck, but are MUCH cheaper than the better alternative's mentioned. It's all about money.

    I tried the fuses with nsound anchors for support. What a difference!

    I must be missing something here.

    The fuse is in the power path , not the signal path. The amp is either on or not. Isnt this kinda like the expensive power cord ??

    Typically true enough, but...

    you are correct . Mr. W , but my speakers are fuse protected. I have yet (correct me if wrong) seen any JBLs that are fuse protected. I am ASSUMING that most fuses in audio are used in the power producting componets.

    when experimenting with fuse size's to get the right one, I wud not be using $35 fuses.

    If the power fuse can make a difference (providing there is nothing wrong or defective with the original fuse and we are not talking about a difference in the fuse mfg. pocket) then on top of all of the other arguments the piece of equipment has a really crummy power supply or whatever this immeasurable difference is that someone says they can hear would be handled in the power supply and you wouldn't hear it. So don't buy a fuse. Go buy some good equipment. Maybe I'm just jealous. Because I'm not the one getting the money. I've got plenty of useless stuff I'd sell and I'd make up whatever story a customer wanted. I suppose if you were really worried about it you would use a protective system that was totally magnetically operated so as sot to have any resistive element in series with the circuit you are protecting, but that's not what they are doing. They don't have enough leads.

    Actually, a component doesn't have to be in the audio path to have an affect on the audio path. I have a relatively cheap dBX amp with power supply and protection problems that manifested themselves as noise in the signal (periodic static).

    If the fuse does not pass enough current, the amp can clip. This could be because of corrosion at the contact points that may not occur if the fuse were of gold.

    Another, similar case in point.... maybe stretching it, but you get the idea.

    I have a Mallory capacitive discharge ignition system on my '64 Vette. After a major tune-up, the car would balk and stall out every time the secondaries opened. I disconnected the electronic ignition, just running the car on the points, and it ran fine..., better than ever.

    Quizicle, I pulled the fuse on the ignition box, and there was minor surface corrosion. I cleaned it with steel wool, replaced it, and the car runs great on the electronic ignition again. (The tune-up increased the cylinder head pressure making it harder to fire the plugs, and the corrosion was just enough to create a low resistance area such that the box didn't have sufficient current to keep up.) When the car comes back from the restoration, I'll put a gold-cased fuse in. (But I'll not pay $35 for it!)

    I agree with your entire post and do not see how any of it justifies that fuse at $5.00.
    A power supply problem and a super duper fuse are worlds apart. The super duper fuse wouldn't help your power supply.
    Actually something else was happening on your vette. unless the tuneup included replacing head gasket, hardly ever called a tune up, I can't think of anyway it would have increased your compression and one of the characteristics of CD ignition is that it is unaffected by things that take place in the engine. The fuse was probably for the CD system only and had no effect on the pts coil cnd system and when it quit working was probably coincidental. I used to own a garage and coincidences do happen and they really are a pain (well it wasn't doing that when I brought it in)


    I don't have enough water pressure at my house. I guess I will get a special valve that opens a little wider.

    since the fuses made SO MUCH difference ,<insert sarcasm emoicon here> , you realize that you've only done half the job.

    Now the power switch MUST be replaced also.
