Good old Charles Hansen of Ayre

He's been saying that same thing for years, and while he's technically correct, whether WiFi makes any audible difference to a given person in a given system/home is highly debatable.
For example, I have done A-B testing with my WiFi plugged and unplugged in the past; and just now, I did some more A-B testing since this post. If you do this enough times, it *is* possble to think you hear significant differences. I did myself a few times, but this effect is not consistent and can vary. In fact, a few times, I thought the sound was actually BETTER with WiFi aa
Then I tried listening to one track over and over without changing anything else. If you do this enough times, the same track *can* seem to sound different even though nothing has been changed. Sure, this effect is small, but so is the difference I *thought* I heard with WiFi on and off...
All I can say is, everyone should try this themselves and decide for themselves in their own systems. Who knows? Maybe some people will hear big enough differences consistently to get rid of WiFi.
I do congratulate Charles for his upcoming USB DAC. Licensing the Asynch USB from Gordon Rankin was a very smart move, and I'm sure his DAC will sound great. Can't wait to hear one. Charles does advocate that hardwired Ethernet DAC's would be much preferable to WiFi, and I do wish Bryston would make a DAC of BDA-1's caliber with ethernet input
