Compared with what, Matt? Hi Martin, The previous fuse in the regenerator was an SR Black. I’m comparing to that, but also trying to compare to the character the SR Purple brought in my Dac. It’s not easy as i can’t compare the Purple and M-1 in the same component, but you can tell the fuses sound signature on the system. |

OK, but the Black was not a very good fuse in the SR range.

I have a question re fuse rating application.
The Plixir Elite dual linear power supply is 12v4A.
I have some spare SR fuses. Is using a 6.3A fuse in this reasonable, or hedging towards stupidity?

12V x 4A = 48W approximately.
So, accounting for inrush current and inefficiency, you want a 1A fuse at most on the mains power side. A 4A internal fuse, if applicable.

MartinT can I pick your experience please. What is the type of differences I can expect to hear going from SR Orange to SR Purple fuses? Also do you recommend I start with the DAC! Thanks in advance.

Tricky. My system uses SR Orange for power feeds and Purples for digital components. This works well for me.
When switching from Orange to Purple you will hear some or all of heightened detail, mid-range presence, dynamics and possible over brightness. This is highly system dependent.
I recommend Purples for digital and stick to Oranges for power distribution and analogue.

Apologies for not being around work has been over whelming in the least!
Mains fuses can and do provide positive benefits in many systems, although you can over egg the pudding with certain combinations no question.
The SR blue & blue are generally to be avoided imho, the have *interesting* effects on soundstaging and timbre plus the lower frequencies become a little disjointed.
The new master fuse, we have had mixed results with this one, some systems its an real positive improvement, what I would say these were used in mains power leads feeding conditoners/regenerators & balanced power units. If you have a *safe* audiophile system, old skool Quad's/Harbeths/Prozac's etc with say Moon/mMridian/good valves/Pass labs/Accu-snooze then it really will surprise you.
For more even handed dynamic systems tread with care, again its a bit of trail and error. In my own systems the Purple absolutely kills the depth and texture stone dead, yes it does deliver a bit more dynamic contrast and *sparkle* buit at the expense of the flow, naturalness and three dimensionality. In other systems its a good tonic no question.
The master fuse in my systems I run one out of the two I require for my mains treatment device, two matsers NO WAY!!!, one on the front end and amplifier side yes its a good step up from the Orange BUT so its the cost.
I made up a jig to allow me to 'run in' the fuses on my cable treatment device so I can determine how/what and why any differenices occur within a very ressionable time frame.

Simple question, HD: How does a something, as simple as a fuse, achieve, or effect all that?

Might find one in your Christmas Stocking, Martin: I won't say never, but I've worked really hard to get the right system balance and it's damn near perfect using: - SR Purple in digital components - SR Orange in analogue, power supplies and regenerators - HiFi Tuning Supreme in low voltage DC rails I'm very wary of doing anything to upset that balance, so no Master for me right now. |

Simple question, HD: How does a something, as simple as a fuse, achieve, or effect all that? That is the $64K question absolutely 
Now if we look at this is real world terms how can a small piece of wire maybe 0.5mm thick (maxium) possible have any effect what so ever, much like how many people feel power cables make zero difference, after all it may have travelled 50 or so miles and many juctions and connectors BEFORE getting to the wall socket.
This is not a debate about power cables, although the effects can be similar.
Back to fuses, over the years being an investigative electronic engineering nature all of these idiosyncratic idea's have facinated myself to point of actually attempting to find any differenices that are actually measureable.
What I can say confidently is that about 18 months sans my top quality T&E equipment although what I was using at the time was still way more advanced than most so called high end audio manufacturers use lol.
I was working on a pre amplifier repair, I always check to see if those pieces that come in are using a non standard fuse as some of them are quite expensive and if you are chasing down a sort or open circuit you could easily wreck a three figure costing fuse!
Anyway I had forgotten to take out this brand 'x' fuse, so I already had taken some measurements before swapping to a stock little-fuse 2amp slow blow unit. Well blow me you could clearly see the 4K sine waves producing much more amplitute variation, before I was looking at around +/- 3mV now it was clearly well over +/-40mV which it stayed like that for over 60 minutes before I swapped back to the original inserted fuse.
Now does this in itself demonstarte anything other than a high peak to peak voltage? I didn't listen to the before and after as I was only using an oscilloscope although it was a 12 bit model which have a significantly great resolution than the usual 8 bits. I can't say whether this has an effect or not, however it was clearly observable & measureable.
Recently though I have observed what I would discribe as amplitute jitter on clock wave forms, specifically after changing components very noticable on both measured and recorded observations and actually listening.
This has happened three times now with the same components over a six month period.
Anyway fuses should they bother you? is it a crock of male bovine excrement or is there really more to it?

The how is a bit of a mystery but both power cables and fuses make a sizeable difference in my system as it shows up these differences very easily. I'm listening to some Latin Jazz at the moment and the rhythm, realism, punch and enveloping feel tell me that my system balance is just where I want it.
Talking about clock cables, the differences can be extraordinary. They're only carrying a clock, not the music signal, so it's outrageous that they make such a difference. But they do.
Still so much we don't quite understand but I go with Tony where a lot of it boils down to noise in the digital carriers and how to reduce it.

I'm not saying they don't make a difference - I've never tried any, and doubt I will, simply on cost grounds. I'm just intrigued by how they can have an impact on sound quality.

One day we will find out what fuses do, mains cables too
All we need to know is what to measure !
Easily said

With all of this, you really need to know what exact parameters you need to measure and which of these actually can be attributed to the 'difference' however what I will say is that lower impedance & reactance ratios within the pathway signal transfer devices do see to have a more desriable effect.
