I have owned and streamed using PC, MAC, IPad, $2K, $3.5K, $5K, $10K, $13K, and $22K streamers. In each case absolutely worth the increased sound quality supplied by that level of investment / performance assuming you have a system.. DAC, Preamp, Amp and speakers to support that level of performance. Also, you choose the best in class at that level of investment.
I have found that with a good quality streamer it does not matter if feed by wifi (wall wart wifi extender) or Ethernet direct from router… but for some reason I have not had good luck with onboard wifi receivers.
Great quality streamers like Aurender clean up the incoming signal, cashe the stream to make up for network deficiencies and do not require any fiddling with your network. My Aurrender work flawlessly from a wall wart extender even when I cannot get the pages to refresh on my iPad.
