Experience with high end fuses????

IsoClean Fuses do make a positive difference. Improvement in overall clarity and detail. Make sure to put them in with the directionality correct. A good tweak is to paint the glass body with AVM to reduce resonance.

I also hear very good things about the Furutech ceramic body fuses.

Soon, Synergistic Research will be introducing high quality fuses that have been Quantum Tunneled. These will be the HOT TICKET!

Some of them have a picture of a diode/rectifier on them.If their
diagram on it is true,it may cause damage to the power supply by
partially rectifying the A/C needed for the power supply.The others
look the same as a stock fuse available at Radio Shack.I would never
put this fuse with the diode/rectifier in it in any of my gear.Ask a
technician,or engineer what a rectifier can do to the A/C side of the
the power supply.Those "cheapo"(as they call them) UL listed fuses do
their jobs as intended.They protect the equipment used to engineer, calibrate, and make our equipment. This is myopinion.[http://www.vhaudio.com/hifi-tuning.html]

Hifitime,

The HiFi tuning fuses you refer too are the entry level aftermarket fuses and they are both sonically inferior to and of lower construction quality than the IsoCleans and Furutechs. I did not and do not recommend them.

"The others look the same as a stock fuse available at Radio Shack."

If you know of any "Radioshack" fuses that look ANYTHING like these, please let me know:

The IsoCleans are of vastly superior quality than your "cheapo" fuses and do indeed provide a slightly more detailed sound with a more extended top-end in a high resolution system.

I notice that you also actively trash the use of aftermarket power cords on other threads, offering no real information about the sonic impact, but only vague criticism about the solder quality of unspecified power cords in an attempt to cast dispersion on these products as a whole.

If you choose to stay clear of the whole notion of improving the sound of your system via improved power signal quality, good for you (at least for your wallet if not for your sound), but a little due diligence (perhaps actually trying the very products that you condemn) before panning a line of largely sonically beneficial products would better serve members interested in improving the sound of their systems than such unfounded speculation.

Dave,Show what it doe's when the equipment is on test gear. Your the one telling people to spend their money,I say save it.It appears to be standard issue fuses.I've read test results on interconnects showing a change in the sound like I hear.Not so with the power cords I've heard.It's the placebo effect.Like I said,it's my opinion,and also what is measured.
Power conditioners are a better investment.They do clean power too.

Its a good thing DLcockrum provided this link to look at the fuses.They look the same as the ones brought over by a friend.He has the same preamp that I have in a bedroom.They look the same as Bussmann and Radio Shack fuses.My friend may have left it in the unit.But that got me thinking when I saw the picture in the link,those look like slow blow fuses only for sale.DON'T put a slow blow fuse in place of a fast blow fuse! Check with the maker,or manual.That what I was always told.They also say they have UL approval.UL does not approve fuses.They let them use their UL listed emblem if it meets their testing requirements from what I understand.Be careful.Make sure you are using the correct replacement fuse!If your not sure,please don't try it.DLcockrum,don't assume I make statements without hearing something first.The one fuse I did say I wouldn't try.♫Links>>[http://www.vhaudio.com/isoclean-fuses.html][http://www.positive-feedback.com/Issue22/isoclean.htm]
