. Which I would prefer in a blind test is another story but there are clear differences in sound quality between all three.

When you don't know which one is in use those differences will vanish. But you won't believe that until you try it and of course you won't try it.

Wrong again ASR, just plain wrong again. You are getting a strong reputation online for just being plain wrong.
I have 3 different power supply’s sat directly in front of me and can hear a difference between each one. Which I would prefer in a blind test is another story but there are clear differences in sound quality between all three.
The one I prefer the most is the iFi Power X, then the LPS from Sengterbelle and lastly the Amazon switching supply.
You could put a sheet of paper in front of me with mathematical differences between all three but subjectively it would not make any difference to my choice, I won’t be sitting down and listening to stats.
Have a great now!

I checked the prices for the three power supplies, and it turns out my guess was right -the most expensive one is, unsurprisingly, touted as the best.

I would encourage you to conduct a blind test between the power supplies to your router and share the results. Until then, I’m happy to accept being seen as "wrong" by those you reference.

How do you listen to a power supply?

The DC component complicates things. However, if there's sufficient ripple, the driver might still be able to replicate some of it when directly connected to the output...

can hear a difference between each one

Nobody doubts that. What we doubt is the reasons why.

Amazon alternative the LPS does give assistance to the sound quality when streaming, a notable improvement. More refined sound, smoother, less harsh digital edge in the music.

Uh huh.

From people who hear differences from router power supplies? Maybe they can provide evidence for all this wrongness.

Compared to the cheap switching power supply that Virgin supplies and an after market Amazon alternative the LPS does give assistance to the sound quality when streaming, a notable improvement. More refined sound, smoother, less harsh digital edge in the music. Considering the price then around £100 seems to be the average for this quality but that said it did not beat the iFi Power X power supply. The iFi was better, cleaner with better separation in the music but the iFi Power X 12v 2.0a is not powerful enough for my Router so I could not keep it there, the Virgin Hub 3 is 12v 2.5a hence ordering the the above Sengterbelle 12v 3a version. The R Core was recommended over the Toroidal version. I plan on modding the case with a small 5v usb 40mm silent fan soon to sit on the vent with 15mm either side free for circulation. I think its a decent power supply and is far better for audio than the Virgin and Amazon power supply I have here. I also noticed that with this R core that the boxy tones, nasal sound in the vocals vanished compared to the other power supply's.

If you had even the vaguest understanding of networking, you'd realise what utter nonsense this is.

Firstly, the TCP/IP network stream itself cannot change any audio qualities whatsoever. All that can happen is dropouts due to packet loss (very rare).

Assuming an adequately rated power supply of any type, the router will simply pass any traffic (including TCP/IP streams containing audio which itself is just network data) unhindered.

A router, switch and associated power supplies cannot make music "better, cleaner with better separation" or remove "boxy tones, nasal sound in the vocals".

I repeat, the streamed music you are listening to is just TCP/IP network data as far as any network device is concerned.

Based on your comments, the web pages you view on this website (and any other website) would be different depending on which power supply your router is using - and we both know that's not the case don't we?

I'm extremely proud to be "plain wrong" in your eyes. You demonstrate an overwhelming lack of knowledge of the key technologies involved.

Glad to see my simple thread from a year and half ago has reignited itself and become a raging hot bed of fire and fury.

You can thank me later.

If this keeps occurring periodically maybe I will live (virtually) forever.

Also hadn't noticed until now but I see I have reached the exulted state of "senior member" thus aligning with my age.

PS. Not sure (cause I havent read all the new stuff and I wont) how it morphed to include TCP/IP (which is something I know a something about)... dont tell me!!!!... I can only assume someone has stuck an LPS into a network device and got blacker blacks etc.

I see what you did there... you are trying to dupe me into reading the new stuff in this thread.

I resolutely refuse to fall for your cunning and evil trick.

Ok then we have a ‘gentleman’s disagreement’ here. Rather than argue my point I am happy living with my ears and happy to choose what sounds best for those.
I appreciate measurements like the anyone else and Amirs work in this field is very helpful as well as people objective opinion.
I actually have returned an £100 LPS today that clearly was not on a par with an £15 switch mode power supply from Amazon for the Router. The difference between the two is literal. The LPS flattened the dynamics of the music. The SMPS just sounds faster, more lively with better separation in the music in regards to instruments and frequencies.
I was pretty shocked to find this. I felt at first the LPS was better but after two weeks I just got quite bored of the sound coming from my amp. I put the SMPS back into the Router and it was like a shot in the arm!
It is still not as good as the iFi Power X but again due to a difference in ampere requirements the iFi cannot be used. I know I am not the only one whom has experienced this. Cheers!

It's amazing what differences may be heard when controls are ignored.

I know I am not the only one whom has experienced this.

No doubt you are correct. Most don't understand the importance of doing these comparisons with basic controls.

 

[MaxwellsEq]

The LPS did NOT flatten the dynamics of the music going via your router because it is physically impossible for it to do that in the universe we currently inhabit. Your brain is fooling you.

I am not sure if I could claim the heady understanding of being universally correct here as this is a subjective choice afterall but the SMPS works very well here for my Router over the LPS. It has greater clarity, quite the opposite of what I expected.

As per my response to your previous poet (post #54)

The streamed music you are listening to is just TCP/IP network data as far as any network device is concerned.

There is nothing analogue happening here - the streamed data (music) is encapsulated in the network data - it's impossible (I repeat, impossible) for the sound quality to be changed in any way.

But as you appear to be a "believer" there's no way you'll ever grasp this.
