Value of a premium Ethernet cable

In my current setup, digital music from a Roon ROCK NUC server travels through an Uptone Audio EtherRegen and a short link of fiber, thence to a long stretch of ordinary contractor-grade Cat 5a cable, and finally to a dCS Bartók streaming DAC.


At substantial effort and expense, I could rearrange things so the final length of Ethernet would be replaced by a single run of something like an Audioquest Vodka Ethernet cable. I'm wondering if anyone has experience of whether this is worth the trouble and expense. Well mostly the expense; the "trouble" is the hobby part of it.


@akg_ca ”…So….I recently did that cable direct bakeoff myself, and the audio improvements were immediate .”… 


@ghdprentice can you share more details on what you baked and how they tastes differed?  Thanks 👨‍🍳 

The part I can agree with is "try it yourself at home"

If you think you are getting noise into your analog system via the Ethernet, I suggest you have a crappy Ethernet NIC so you are expecting magic cables to fix a bad design.  If you tested you would probably find a lot more garbage is from the processors in the router and switches and not RFI. If your receiving device does not take care of it, it was not correctly designed to work in the intended environment. Blame your box, not the cable.  As far as which cable it is possible to transfer this noise, it is only the last link as the signal is reconstructed in the router and any switch. 

If you believe, so be it. 

What you hear is what your brain says, not the actual sound.  -140dB noise flor? Well that is truly fantastic so quite a great system. Not sure how you get that as even a Bryston amp has about a 114 dB SNR. -140 is pushing Johnson noise. With what source material? A CD with 110 dB dynamic range compressed to maybe 40 to make it loud?   A super great LP direct to disk that maybe has 65dB?  Or do you have some first generation  24/192  digital files before mastering?  I bet what you are actually hearing is more like -80 dB if it is actual physical, not perceived. 


Oh, yea, guess I'd agree a lot of big box cables and hubs are junk. So junky I only get 360 Mbs on my computer with Amazon cable, self terminations, Netgear dumb hubs and the supplied Spectrum router and Modem.    Not saying Belden is the only or the best but if you buy their wire, it will meet spec.  I have had no problems with Netgear hubs.  Instead of expensive linear supplies, I just put a ferrite on the wall wart cable.

I’m sure I was getting noise from my Panoramic modem that the streamer is plugged into directly.

The magic Ethernet cable cost $130, came with a 60 day no questions asked return policy and absolutely sounded better than the $20 Belden cable.

No placebo effect, and my bias was in fact against the magic cable - I wanted to send it back.

Tomorrow I will be trying out a black-magic Ethernet cable to compare with the magic cable, also returnable.

Either way this was a low cost solution that didn’t require another powered device that I have no room and no spare outlets for.

Yes, there is abundance of snake oil in this industry but there are also plenty of really effective reasonably priced products.


@macg19 try giving a value Amazon optical set up a try.  Under $100 without LPS. Couple hundred with an LPS. Some like it others don’t and it’s returnable.  Worked wonders for me. Set up is  router-ethernet cable- FMC-Optical cable- 2nd Fmc - best ethernet cable- streamer. 

FMC Need 2:  

Optical cable Need 1:
LPS Optional but worth it , powers 2 FMC’s need 2 cords.
