Quantum Science fuses.

I would add that if you do hear an improvement, stay with it for a few days, then revert back to situation before you made the change. If you hear a degradation of sound, then the change was a genuine improvement; if you don't hear any reduction of sound quality, then the change was not a genuine improvement.

That's not a reliable method since just like when you put the fuse in, you know that you have taken it out and you can't 'forget' that, plus since you just made a change you are listening differently to normal, again the same as when you put the fuse in.

Like I said if it fixes a problem then that's different, but on a system with no problems it's very hard, I think impossible, to accurately verify the effect of tweaks like these fuses.

All said and done if someone is still thinking there is a possibility of a better sound go ahead and try them and report your subjective findings here.

best way is for someone to switch fuse when your out.lol

Like this approach.

Its what I do as well.
Sanity check everything,

there is a psychological aspect to all this stuff.

I do this for with all changes of cable, and in the one instance: a Hi-Fi Tuning fuse that was given to me.

As to the analytic/critical mode - my modus operandi is to make a change and just play some music. If there is a definite change it will leap out to me whether I want it to or not. If it doesn't and I have to really listen hard for any change, then as far as I'm concerned the change either doesn't exist or is not important enough for me for it to remain in my system.

Just had a cursory "poke round" any of my set up that could possibly benefit, and already it's all too technical for me. Shame really, I was prepared to take a punt with a bargain...

Here's an idea for you Steve. Ask Mrs P to randomly switch fuses over a few weeks while you're out (including some no change for the null hypothesis) and keep a record. You keep a diary of listening impressions while you listen. At the end compare notes and see if there's any correlation.

Great idea, which unfortunately falls at the first hurdle. I can't be trusted to tamper with anything electrical. But she's worse!

MF's A5 integrated manual says that there are no internal fuses that can be changed by the user. The only other component (probably) that could be messed with is my Project Tubebox phono, but i can't find any info on that. Nor for the Marantz CD player. And I'm guessing that the power supply for the Monarch turntable wouldn't benefit. Unless anyone here knows different...

[Macca]

You have fuses in the mains plugs though?

[Gazjam]

Steve,

I swapped out the fuse in my TT power supply, subtle but noticable improvement.
Worth a go Id say,
but dont spend too big on this one, less return than in a dac or amp.

and yeah,
Mains plugs a good shout.

That is one point I struggle with. How can a PSU fuse on a turntable improve the sound?
It is not in the audio chain.
