Ethernet cables

No, I don't think it's worth spending a huge amount.  Out of curiosity, I purchased an ethernet cable that several members here touted on Amazon, easily returnable.  That's when I found out ethernet cables can sound different.  It made my system sound worse than the standard issue provided by my cable company, so back it went.  I was not about to wait several hundred hours to let it "break in".  I then tried DH Labs Reunion ethernet cable as it was also returnable.  I think it sounded better. It definitely looked prettier, so I kept it.

Ethernet cables are directional whether they are marked or not- at least the silver plated wire ones are.  So if it sounds bad, try turning it around.  I bought some silver plated wire Pangea ethernet cables about a year ago.  They made my previous NUC based music server sound better.  They were not marked but they were directional.  It wasn't hard to tell the difference.  The highs were edgy and grating one way and smooth the other way.  I had the same thought at first- these silver plated wire cables sound worse than my basic cheap ethernet cables.  Then I thought to reverse them and they sounded much better.  I don't think it took much time to tell the  difference.  So I had to try out each cable both directions, and I marked them; but by the third one I could tell right away.  Also, the cable closest to the server is most noticeable with the cable between modem and router the least noticeable.  The Pangea are very reasonable offering silver plated Cardas wire.  I later bought some AQ ethernet cables with thicker silver plating.  It improved the sound but I'd say the improvement didn't match the increase in cost.  I kept the AQ because cost is a secondary issue for me at this point.

Hearing a difference in ethernet cables is system dependent.  The better cables make the TV picture look better but I don't hear a difference with my HT system setup.  With my stereo system the difference is night and day.  I have found a handful of songs that have bad mic clipping with my stereo system.  I can't play those songs on my stereo, it's too grating.  Play the same songs on my HT system or in my car and I can't hear the clipping at all.  The detail just isn't there.  I can hear guitar strings rattle in some songs on my stereo that cannot be heard in the car or on the HT system.  You just don't know it's there until you hear it in a more critical system.  So, careful what you wish for.

I do not believe in audible differences between 2 properly made Ethernet cables of Cat6 or better. What I do believe in is never using the absolute cheapest example either. So I settled on Belden cat 6e. Belden individually tests each cable to ensure it’s up to proper spec. I chose cat 6e over 7 or 8 because there’s some evidence that the extra shielding in 7-8 can potentially cause ground loop issues. And cat 6e avoids this and is WAY faster than your music is streaming. It’s my opinion you can’t do better for an Ethernet cable. And it’s about $30 shipped.

By all means spend $2000 on a data cable if you just like having cool, expensive cables. Nothing wrong with that if you can afford it. But I do not think your $2000 Ethernet cable is getting you any actual advantages.

Not many spend $2000 on an ethernet cable. Those who do, will have systems to match. And the effect of the cable would be noticeable compared to the Belden.

The Belden is a reasonable start.

My Triode Wire Labs ’Freedom’ have also been good value, in keeping with my system cost.

Going down the digital path for several years now, I've made a number of changes from DAC's to music-server/streamers, and the cabling that goes along with them.  There has been a lot of good information rendered in this topic.  What I have found on my digital journey is that while cabling does make a noticeable difference, getting a good solid digital equipment foundation is more important, then honing it with the right support components like cables.  The DAC changes I've made seem to have made the most noticeable difference in sound improvement.  Then going to a better music-server/streamer and re-clocking the USB signal certainly improved the sound.  Then I worked on improving the USB signal from the server to the DAC with different cables.  The improvement in streaming in my system happened last not with a new streamer but with changes upstream in the digital signal.  When I listened to the exact same song loaded onto my music-server/streamer, then streamed from QoBuz that same song through the same device, the streamed music left something to be desired.  Adding in an Ethernet re-generator from the modem to the music-server/streamer brought the listening between the two sources much closer and difficult to discern.  At that point, I felt that changing out the Ethernet cabling would be next., so I tried an Ethernet cable that was notably more expensive than my present rather inexpensive one and I noticed a slight improvement in micro-detail bringing the music experience to what I was hearing just from the loaded music on the music-server.  At this point, I don't think I can improve the sound from either music loaded on the music-server or the streamed music unless I start changing out equipment in the digital path.  (like a DAC or music-server/streamer)  What this experimentation taught me was getting better USB and Ethernet clocking/lowering jitter, and noise reduction made the most difference and allowed me to then hone-in on other changes like cabling to squeeze out the remaining sonic improvement.  In essence, get your digital components the best you can, then do your tweaking with cables...
