Again, if you are hearing a noticeable difference and not just 'a feeling'.
Then it can be measured!

Almost like the line from Predator;
"If it bleeds, we can kill it"

I have experience of this 😀

No one, from what I've read, can give a creditable explanation as to how an after market fuse works, as such, saying it does so by magic is as creditable as quantum tunneling or anything else.

In the 70s I rewired a distribution block with solid core cable and hard wired it to the back of a wall socket, and heard a clear improvement.

Unacceptable? Aye. That which is/was hard to accept. That "other" "hard to credit" factors can influence sound quality, as was generally regarded, once. You don't have to go that hairshirt. You can start with temperature and humidity. And then jump to cable directionality.

Shakey stones. Must have heard of them. Along with crystals and tiny blocks of wood you attach here there and everywhere. The list of stuff is endless these days. Honest to God I am waiting for someone to bring out a rang of audiophile clothing to combat RFI, as I've said before. It'll happen.

There's no escaping RFI. The question is does it impact on audio? As I've said, some will say it doesn't.

Religion. Its a belief system. You believe, have faith - or you don't. Some people are "Doubting Thomas's"; they want proof. JC said that he would rise again on the third day after his death. He appeared to some of his disciples, but not Thomas. When they told him about the visitation, he didn't believe them, saying he would only believe when he could physically put his fingers in the wounds of JC and know for himself. On the next visitation JC presented himself to Thomas and offered him the nail wounds in his hands and that in his side from a spear. Well, Thomas had his proof then and was repentant for not believing in the first place. Of course, that all depends on whether you believe the bible to be what it's supposed to be.

UFOs Never seen one. Believe they exist. Believe they're real simply because of the testimony of other, more than creditable expert witnesses. There's ton's of "evidence" - if you're willing to accept it. The problem is, people would rather simply dismiss it. It's too much of a stretch for their imagination. Simple question: why would anyone with some level of public reputation put themselves forward with claims when they will be faced with ridicule. What does anyone in that position have to gain?

Look on YouTube. There's loads of accounts for anyone with a genuine open mind. Go an investigate Timothy Good. He's written a few entertaining books. Go and investigate accounts from astronauts. Maybe they lack credibility for you. At the end of the day, you believe, or you don't. If you don't, it doesn't matter what anyone has to say, it won't bring about a change of mind.

I'm just playing devil's advocate. I saw the thread and then wondered how PB would be regarded if he was to appear on the scene unknown. Would he be regarded in the same way as he generally is. Or, with the passing of time, would his "treatments" be more acceptable to a more open-minded (gullible?) audience?

I'm sure, with the prevalence of social media, he would be for both reasons.

So, back to the Magic Tubes (not wanting this thread to get completely derailed), I seem to have settled, through quite a lot of experimentation, on 11 out of my 14 deployed on digital and DC power cables. I have three spare ones left.

The overall sound has a lower noise floor with smoother, more detailed treble energy and very tight and deep bass. Dynamics are very good indeed. The music ebbs and flows and the midrange, especially with voice, is liquid and soars beautifully.

The system has a fine balance between high levels of detail and not getting into harshness. This has been my goal ever since dedicating my system to streaming and is a tough one to get right. I knew selecting the ES9038 DAC chipset was going to present challenges and it does. However, I wanted to hear as much detail as is possible to extract from the signal and here the Sabre DACs are king. The Magic Tubes are a fine tweak but are very impressive in taking the system towards my preferred sound. Indeed, playing some of my shit-list of poor recordings is a revelation with almost all of them now listenable.

Money very well spent.

I finally succumbed to getting 5 tubes after having 2 free mini doughnuts on my mains cable (on my speaker cables a backward step).
They add a bit more depth in my system and further allow sound to suddenly appear from the depths of space and time ⏳😉

Interconnects near amplifier and initially coaxial and AES cable but now trying the last 2 on the DC cables

Thanks for the tip Martin seems like on digital they are not as well suited I am bit surprised I am hearing more depth and body

Yes sure are I rate this higher than the Black Ravioli big pads in my system for they are doing and that is good praise
