We have tested many servers and streamers and they all sound different
we started streaming journey years ago by using laptops, pcs and a Mac Mini using Jriver then Roon
we started with an Auralic Aries s then Aurender n100h an Sotm super modified custom pc, Baetis then we were introduced to Innous and their servers were clearly better. we were with Innous for many years till we discovered 432EVO a server line from Belgium that offered a modular, upgradable architecture. and this line of servers sounded even better.
in fact we tested an Aeon vs a 27k Innous Statement and found the One third priced 432EVO aeon, and found the Aeon to sound just as good.
and the Aeon also outperformed the aAurener 10 and N20, while costing less.
So yes servers do sound different and are as important as the Dac.
