If you have an amp that needed 2 or even 3 fuses and you decided to use 2 or 3 light blue fuses, a full complement, would you get better or worse sound from the amp using only 1 yellow at the proper direction at the proper location closet to the IEC inlet on the amp? 


@middlemass,

Great info. I've ordered the yellow for my preamp. This will be my first ever fuse upgrade and the directional rules had me a little confused. 

Sometimes it takes a little courage asking the questions you want cause no one wants to look 'stupid' to others. And asking that question, couldn't be more farther from the truth. So if you don't ask...You won't know.

@georgehifi, doing research on fuses about 3 years ago I stumbled upon this 2017 you tube video by Paul McGowan the chief electrical engineer of PS Audio about 'Audiophile fuses'. He didn't believe that something as small as a fuse could effect sound quality either.

Well, he does now, in fact he has completely changed the design of his products to make them more fuse swapping friendly.

Don't believe me, go to his PS Audio blog and you will see years of PS Audio customers sharing their stories on fuse swapping.

I got 2 light blue on the way and within ninety days - a hell of a long grace period, I'll probably get a yellow, and then...

  


Let me get this straight. I specifically give you 1 video of Paul McGowan videos about fuses, coming directly from his mouth.

Paul McGowan the chief electrical engineer and CEO of PS Audio completely revamps his fabrication process to make his ENTIRE line fuse friendly and you still don't believe?  

Ok, no problem. So why do you even take time out of your life to even post here? Is it that your only interest is to get 10,0000 posts?

Just saying.
As I upgrade my system I’ve yet to purchase a preamp for my newly purchased SS amp and dropped a couple of light blues in a NOS Panasonic SA-HE200 reviver and was very jolted to hear a massive, scary even, upgrade of the sound quality of said receiver.

Just as everyone else said. More quiet, dynamic, larger soundstage, black background etc., and it’s only been a few evenings I’ve had the time to play my little rig!

The fuses are not even burned in yet and the difference in PRAT and is non fatiguing and draws you in to listen is only going to get better. My best least expensive upgrade ever.

I emailed Mike and told him: ’send me two black. I’m gonna take the two light blue and trade up within the 90 day grace period for a yellow’ for my new amp. He got back to me in a timely matter at that. Buy these.
Frank,

You did nothing wrong. I would imagine by your actions alone you have introduced not only PPT and QSA but SR Purple as well to probably thousands of members here on agon. Which I thought that is what we're here for. Which to me is a positive thing you have done. It’s called sharing.

Ignore the negative posters and they will slink back from whence they came and hide behind the moniker they’ve created here to just bully others as they have nothing positive to give, or anything better to do.

The Cable Company will be taking orders for the SR Purp the first of October for anyone who wants to know.
docknow,

I know you can trade in/up the QSA fuses to purchase other QSA fuses, but was wondering can you trade up/in to the QSA stones? We maybe able to trade in/up to the QSA stones?

So you wouldn’t be losing any monies on the QSA fuses and still be able to get the SR Purp and have the benefit of another affordable tweak with the QSA stones? I’ll never know until I ask. Thanks for making me think about this.

And this is Mike's response:

'Not really. I would say the fuse upgrade has more bang for the buck anyhow.'

That's not a yes, or a no.
