This recent exploration of my streaming set-up all started because I purchased the ENO Ag and a Network Acoustics network cable. A member here alerted me to this unit being for sale and I was fortunate to jump on it quickly.
I have a Mojo Audio server/streamer (DejaVu) and their DAC (EVO B4B). I have a 45 foot long network cable from my router into the server and then USB into the DAC. I added the ENO ahead of the server, by first bringing the network cable into a Bonn N8 switch, then the Network Acoustics cable from the switch to the ENO, then the short network cable attached to the ENO into the server. The server runs Roon and serves as both the core and player. I stream both Tidal and Qobuz but the addition of Qobuz is recent.
Even before trying the different set-ups, I thought the system sounded very nice, organic, full-bodied tone, and powerful, with good extension and staging. My initial opinion was that the ENO added something that made the music sound just a little more real somehow, but I haven't yet been able to point to one particular thing that causes that. My plan is to stick with it for some time and then take it out and decide whether I am missing anything. Leaving new stuff in for a while and then taking it out to assess differences has been a good method over the years for me to evaluate what I like the sound of. Right now I would say the ENO filter was a positive addition but I really don't know why yet until I listen more.
The Mojo Audio stuff is built great, with outstanding power supplies, and both pieces use high quality I/O boards by JCAT such as this XE USB board. I suspect the already high quality pathway of my server/streamer and DAC have a lower need for corrections brought on by small add-on boxes. Even the ENO and their cables are certainly less than a revelation, but may be one of the few add-ons to make a positive difference.
