I've been using a NAS for the last 7-8 years connected to my router. It never occurred to me that sound may suffer that way until a friend of mine suggested recently that i should get a separate network switch and thus isolate the NAS as well as the Network streamer. I did and can definitely say that i really like the difference it has made. It's only a cheap Netgear one, but sound is better. I won't go into details trying to describe it but it definitely has made the difference. I suppose many of you are probably doing it this way already but i wasn't and am chuffed to bits that such a small next to nothing investment can improve the sq.. 👍
