In Reply to: RE: Fuses and fuses posted by Ryelands on June 15, 2016 at 03:13:14
"It's funny how, when offbeat issues such as fuses come up in audio circles, folk invariably hit you with a bit of cod psychology then ask, Have you any figures to back up that claim?"
What was offered up were a couple measurements with no correlation to fuse operating performance or a subjective review of SQ. In other words the post had no substance. It's like saying I measured two lamp cords today. One was 3 feet and black in color, the other was 8 feet and white. So?
I agree that opening time versus percent of rated current is a key parameter in choosing a fuse but it tells you nothing about how it performs at average operating currents and less about its dynamic performance (peaks).
Neither did the OP's measured parameters. In fact, they told us nothing at all.

But it was a beginning, however modest. I've not prior seen even static data (as here) for "audio" fuses and, until recent experience suggested I was wrong, would have derided the notion that there were such things. So, partly in an attempt at good manners, I tried to comment constructively.

I was addressing G-Squared's (perfectly proper) point. What fmak's measurements told us was beside that point though, sadly, I didn't stop others scoring cheap points of their own rather than, just for once, keeping quiet.

but seriously, I have long eliminated as many in line mains fuses as possible and have opted for either the European plug or the US socket system in my main audio system.Modern mcbs and rcbs are so sensitive that they afford the necessary protection without going over the top with multiple high reactance fuses inline.
Some of the responses clearly demonstratae the lack of any understanding of how complex devices can affect SQ in audio systems. Sad but yet such posts keep on being made. If a ground bus bar plus a few cables costing hundreds of dollars can affect SQ, why shouldn't anuything thing else that is inline with a mains transformer? Such inmates have clearly not heard of snubbers or their effects.

Me too though I suspect it's easier to do so safely under the UK's ring main/ fused plug system. I have two audio-dedicated mains circuits, one for digital, the other for analogue. Though each has a fuse in the plug top only, the systems comply with the Regs. Even so, upgrading the fuse on the analogue side did make a perceptible SQ difference.

Curious as to why. Both strike me as, at best, no better than the UK design, esp if you upgrade plugs and sockets.

Agreed. Is any other domestic device typically fused at both ends of the mains cable? And that despite audio kit being the only ones whose performance is (arguably) degraded by fuses.
are not fused. They are easier to clean and the connection systems are better. The 'best' MK plugs are a pain to connect and clean properly.
I still use the ring main system but isolate using ultra isolation transformers with ac regenerators.
I don't have to solder bridge wires as in the case of UK plugs to get rid of having 2 fuses in series for components.

Got it. Same cat, different swing. I fit a fuse in one plug top only (as it complies with Regs), hard-wire via this and that to IEC sockets and omit or by-pass fuses on the devices. Good sound, good and cheap.
I agree re MK plugs and use MS HD Power Plugs instead - better metal, much easier & bigger connectors but reasonable prices. I also agree re isolators - big SQ difference as well as good for safety.
In fact, it's all so audiophillic it makes your eyes water.
