15A or 20A Power Cord

Quanmer,

Sorry but I did not see your post until today. Hopefully you have purchased the hi-fi tuning fuses by now, if not, I echo Lenny_zwik's observations. I have the gold plate fuses. They sound great. I do not have any experience with the other more expensive lines. I will tell that I heard that the Silver Star can corrode but I do not know if this is true.

I would email the manufacturer about what fuses are needed and how many. If you cannot decide what line of fuses to get I would isolate a particular component, I would recommend the Ayre MX-R if you have that, and do a comparison. There are several fuses in each mx-r and it would be a bit of a pain to change everything out but this would be the only way I know to do a comparison.

Good luck!

Lenny_zwik,

Did you change the fuses in your Nagra PL-L? Are there any fuses inside? I have not checked it out.

I use the Shunyata Anaconda's on my Ayre C5Mp cd player , KXR preamp and Levinson power amp also have one on the Shunyada V-Ray . Iv'e owed and tried many expensive power cords over the years before I fell for these . The 20 ampers are a solider fit .

Looks like the 15 20 amp power cord is settled, now we are into fuses.

By the way I have a Hydra 2 that uses a DIY Furutech power cord, and the Rhodium 20 amp furutech plugs.

Sounds better to my ears than the other DIY power cord with cheaper parts, so kepping with the topic,the quality of the 15 or 20 amp power cords matters,at least to me.

Now fuses.

Thirty years ago I read in my trusted Audio Critic mag that speaker protection fuses degrade the sound wherever they are used.

Simple enough to try for myself.
Don't need a degree in electrical engineering to try this .
So I replaced the fuses with simple copper jumpers of various coinstruction.Solid core copper(bits of Romex) and old speaker wire(mostly staranded copper).
Not only did I discover that the fuse imposed a sound , so did what it was made up of.

Skip ahead thirty years (never any fires or damaged gear), I kept up the practise of bypassing speaker protection fuses.But around this time I read about IsoClean fuses.

They weren't going to put me in the poor house to try a couple so I did,and yes they did sound better than the stock cheap fuses.

Then a few gear changes , and now comes the HiFi Supremes, which I bought for my amp(DecWare Zen select) and
phono pre(Manley Steelhead).

The HiFi supremes aren't adding anything more to the sound than the stock fuse were.
They are adding less.

There is more clarity now than there was running stock.

But would I have noticed the improvemnt if I were running cheap stock power cords?
