Ethernet cables

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...
