OP,
Let me be clear. Just buy a $59 wifi extender and plug it in next to your system. Plug your streamer into that. I bought two streamers with internal wifi recievers, one was an Auralic Aries G2. It was a mistake. Internal WiFi, even on fairly expensive streamers do not work well. My $150K system runs off a wifi extender. I know of many others. Do not keep the requirement of wifi on your list. Companies that make the very best streamers like Aurender do not have internal wifi receivers. This is because they are not required and put noise inside of the box. You do not want a wifi receiver inside of the streamer… especially when the problem can be solved for $59.
