What I am hearing with ENO Ag installed between a Cisco Catalyst 2960 switch (using optical SFP) and M218 into DSP5200SE is a larger 3D soundstage with more aggressive dynamics, and more forward presentation. Depending on the mix, vocals and bottom end can be in your face without seeming unnatural. Tighter bass. It also seems louder when set to the same level. Live performances, such as the Paul Berner Band's Road To Memphis, sound balanced and realistic.

ENO replaced Cable Matters CAT8 > Uptone EtherREGEN > Shunyata Venom (into the 218), which combination had clearly outperformed the variety of different ethernet cables I tried since going to 218 instead of Allo DigiOne in 2019.
