Ethernet connection for best sound quality

WOW...  A LOT of information thrown out here.  I know that along my digital journey, I started out with a good laptop used as a music server using JRiver as the software to manage the music sent to a good USB DAC.  While the sound was really good and bettered my CD player at the time, it still was not a good match for sound quality as my analog set-up.  That all began to really change when I went from my laptop-based music server to an Innuos ZENith MKIII.  The music finally started sounding (well for lack of better words) "less digital".  And, music that I had loaded on the music server sounded better than streamed music through the same music server using QoBuz.  Researching further, I decided to try and improve the digital signal transmission first by purchasing the Innuos Phoenix USB Re-Clocker, which made a noticeable improvement in the micro-detail of the music.  I was able to finally use digital as my main source of pleasure listening.  Thinking further and more up-stream, my research led me to improving the Ethernet signal.  I purchased an Uptone-Audio EtherREGEN device and $-for-$, it was the most noticeable improvement in the sound than any other digital device I had added into the digital side of the system.  Background got quieter and micro-detail improved.  In essence, a more realistic portrayal of the music.  In my opinion, noise, poor clocking and jitter are the worst enemies of good digital playback and minimizing them with devices and cabling that can help minimize the effects of those is the path to take for improved digital sound.  Of course a really good DAC. CD transport or CD player, or streamer really help in that digital chain, however without really good clean jitter-free signals, those great components won't be able to perform to their utmost.  I wish you the best on your digital journey !
