Audiophile Fuses

[ssfas]

A fuse and a CB are designed to perform the same task, that being ADS. They are there to perform ADS in the event of a fault and to ensure the circuit does become overloaded. A fuse should never be replaced under load, neither should a CB, both will arc if engaged under load. Basic safe isolation procedure will ensure that will never happen. Just sayin'

That is incorrect in UK systems.

The contact breakers in the consumer unit are designed to disconnect power in fault conditions extremely quickly, in a matter of milliseconds. To do so, the earth loop impedance must be below a certain level. These have to be checked on every circuit in your system and are reported on your test certificate.

We have fused plugs because we use ring mains. Whatever the rating (3A, 5A, 10A or 13A), they are designed to protect the plug and the power cable from overheating and catching fire. They have to comply with BS1363 and BS1362. The fuses are silica filled ceramic.The costs of certification are too high to make it worthwhile for any audiophile fuse company to make them.

Safety fuses are slow blow with a current factor of 1.9. So a 13A rated fuse can carry a 24.7A current for 30 minutes before it blows. So the performance of circuit breakers and plug fuses are completely different.

As for fuses built into your hifi components, no regulations apply and it's up to you, bearing in mind the manufacturer's warranty conditions. Gryphon strongly advise me not to mess around with the installed 8A fuse and if I used a SFDB and it went wrong, I don't think they would be interested in fixing it.

Other than flicking breakers, nothing from the wall sockets back should ever be touched, let alone modified by anyone other than a qualified electrician. The 100A fuses either side of the meter have anti-tamper seals and can only be touched by the UK Power Networks on the electrical supplier.

The only fuse in my system that I can change legally and without affecting the warranty is the 2A fuse in my streamer power inlet socket.

What people do in the USA or anywhere else may be completely different, not least because ring mains are unique to the UK.

Any comments regarding Audio Magic M2 fuses?

Not much discussion about these here.

Have M2 in my streamer and DAC. Expensive but great fuses. Compared to stock, they are more resolving, background is way blacker, and have an 'organic' quality to them, especially in the mids. Very well balanced, though not dead neutral like their Super Fuse

A friend uses a few Audio Magic M2.
He described their effect as “somewhat softer” and “especially more emotionally touching”.

Needing 6 fuses for my CH P stuff and being too poor for QSA, I ordered 6 M2.
I do hope things don’t get too “soft”.

I've tried other fuses ,not that one.They all can change the sound .Right now I'm using a SR Pink in my CSLS pre-amp and like what it does .
I've been a fuse makes a difference supporter since the old days when the Audio critic mag suggested bypassing the fuse in Magnepan speakers.

I used the SR up to the Purple and AM fuses before the Master, followed by some QSA red and red-blacks. The Swiss Digital Fuse Box (SDFB) from Vera-FinAudio is a substantial improvement over all of them. I have seven in my system (there’s now also an alternative version, the Infinity Fuse). There’s a “Swiss Digital Fuse Box Anyone” thread on WBF.

SDFB is not an option with CH P, as these components each have two fuses with different Ampere.

I have the Infinity on order.

Are they still in business?

 

[engadin]

To the best of my knowledge, yes.
Alfred Kainz of high end electronics accepted my order and promised delivery within 10 days, as he had not all in house.
Several friends and myself had ordered at Alfred before, nice gentleman and decent seller.

There is something to be said for doing a search --"Audio Magic"

Great seller.

There is usually a primary fuse at the cord input. SDFB can be used there. The smaller internal fuse will need to remain a fuse.

Prior to the PS Audio Directstream Mk II dac, their Perfectwave series didn’t have an externally located fuse. They had two inside, one for power circuit, so the top had to be popped. With the popularity of aftermarket fuses, they moved it to the back for the Mk II and the new PJM dac.

Already did. Website operational and up to date but email not returned. I wanted to get something upgraded but can't take the chance on it disappearing for good.

Try calling?

No answer.

No answer.

Wow, I wonder if he's sick or something. What does Albert (or Alfred?) of Highend have to say?

 

[Tabl10s]

Is been like this for a while. Three Cable Company still carries his products.

 

[Tabl10s]

Never heard of A Albert.
