Wi Fi has a limited bandwidth. For instance with WiFi 6 I get about 365Mbs. With a gigabit wired connection you normally get close to 1Gbs on most networks today. I have heard you can get high definition audio with 100kbs, but I reserve my opinion it does not sound good enough. If you can get 300kbs from a streamer WiFi, it sounds pretty good. I bet on a higher end system than mine, the detailing higher end systems can achieve, that those folks could tell difference in not only bandwidth, but preamp, DAC quality, and power amp quality. The internal components and design make a difference. I think some people in this forum have experience with both wireless vs wired. My question would be if you have a Bluetooth, or wireless setup.....How good is the DAC? How good is the reciever that captures the bits and bytes flying through the air? Of course this is compared to a high end system that is wired. I think the electronics powering the speakers is a Huge concern. It boils down to your ears. I know I can listen to my wired speakers for 4hrs of critcal listening and want more if time permitted.
