I wish that were possible, but the necessary equipment is way beyond any hobbyist's budget.
No budget audio analyzer or oscilloscope is capable of sorting out the differences we're talking about here.
I'm afraid that the best instrument available to us is our ears, however unreliable they may be.

Well, inducing 2,4 GHz into poorly designed electronics could have an impact in the audio range? I do this for peace of mind. But I cant say I hear a distinct difference. On the other hand, I dont use poorly designed equipment

If you can't measure a difference in the audio output with a decent 24/96 sound card and some basic analysis software then the chances are that there is nothing bad going on.
The thing is that there is "nothing bad going on" as far as reasonably priced measurement equipment and software can tell. But the sound is different.
For example, can a "decent 24/96 sound card and some basic analysis software" measure width and depth of a sound stage? Resolution? Clarity?
In my experience, it can't.

Of course a bit of HF noise can change the depth of a soundstage. Nope not buying that. You need a significant change in FR to affect the perception of depth. For width you'd need either cross talk of phase shifts.
No credible mechanism for that to occur in this discussion.
I agree. For people who think that everything can be measured (beside human hear), I'm very curious about characterisation tools that would quantify width and depht of sound stage, resolution, clarity... just curiosity.
It is not because you can't measure things that they don't exist.
I agree also that well engineered streamer/DAC should not be sensitive to current leakage through Ethernet cable (Melco is a good example of how to manage incoming Ethernet - they originally are network experts).
I would think the majority of streamer and DAC are not immune to current leakage.
Do people think that what uptone audio is designing about Ethernet regen device is just BS?
Same for SOTM, waversa, Aqvox?
Again, please give a try before saying it is all BS.
The soundstage has been created but the mixer (in a stereo mix) it's interesting to study how this is done.
Soundstage is not defined and can't be measured as a single number like ST = 7.21 . But you can study things like the polar pattern of a speaker system and fairly well predict how the soundstage will be like. And those polar patterns are measureable.
It's like asking to measure the comfort of a car. You can't, mostly because we humans suck at defining comfort with a single parameter. But you can look at road handling, chair stiffness, internal dimensions, and get a fairly good idea about its comfort.

As Uptone are playing on FUD yes. I have no need for any of these devices so no interest at all in trying them, but would like to save people from wasting money.
Uh huh
. It's taking 0% CPU time according to my profiling tools. Also looking at kernel time which is miniscule.I heard significant difference between Aqvox switch and my regular Dlink on LPS.
This is the goal of the thread, how can you help me to get similar result (because it is very good) at a lower cost ?
The only difference you seem to be talking about is noise ingress thru cables. So theres no equipment that can measure noise? Thats the real BS.
I never said that there is no equipment that can measure noise. I said that I, as a hobbyist, can't afford such equipment.
Plus AFAIK there has been no study thus far correlating different "noise signatures" with "varying sound quality". And that would be very difficult to do, since each dac design will respond differently to different noise signatures.
But these are largely theories, formed in order to explain why we are hearing what we are hearing.
I'm open to suggestions of what else may be in play.
And please, no "what you are hearing does not exist" stuff. I'm not alone in this. People used to say that audio cables do not sound different. And then that USB cables do not sound different. I know all too well, I used to be such a skeptic. But then I sat down and listened with my own ears, in my own house, and that changed my mind. Now I can tell when one of my audio components is plugged in to the wall the wrong way (switched phase with neutral).
In other words, my life is pretty much ruined. If you can't hear these differences, you are the lucky ones. Get out of this while you still can.

Used to say?
90% of the "contributors" to this thread might still be saying it. Just a wild guess
This discussion is rather funny for an ICT guy like me. The only way i can see that a switch can influence the sound is when it's in the same powercircuit as the analog devices, and the power supply of those analog devices can't shield the analog audio circuits from the noise that a psu of a ICT device create. But use an other power circuit, or use audio stuf with a good shielded psu and that problem is gone. I use an old pro Cisco blackbox switch, wich does the job perfectly...
Ditch the hub, direct link from source to desination with a fibre converter at each end. Single mode glass fibre if you are feeling really paranoid.
