I'm guessing the "wireless" connection to the speakers is Bluetooth?
My thought is....you're not going to be able to get the same quality signal from BT as you would with a hard wire, right?
If this is the case, I guess if you're dealing with a lower end system and cheap speakers, you won't know a difference, but if you've laid out some cash for some good speakers....you'd still wanna go wired, right?
I have Klipsch K-Horns as my front speakers and a pair of Klipsch Cornwalls as my rear channel speakers...if I had something of that quality with a wireless option, I'd not want to opt for wireless unless there wasn't a choice, if I wanted best possible sound I'd think.
Also, with BT...is there a delay problem potentially?
First, I don't know what the wireless protocol is as I'm on /. and clearly have barely skimmed TFS, muchless TFA, muchless researched further.
Most of those problems with BT are old. aptX has had a lossless protocol for about 7 years now, however limited implementation there has been with it. There's latency to BT of course, but that latency is easily compensated for on the processing side, otherwise all the people with AirPods would never watch videos with them. There's already a buffer to live shows anyway, is it really going to bug you when you're watching your sportsball or racing that you, in your bubble, have 200 ms more delay compared to your friend who is watching at their house? If it is, you just turn off the FlexConnect for the game or race and enjoy stereo instead.
Frankly, I think Atmos has a chance to actually succeed where quad and surround failed. Partially because it's meant to be smart enough that the consumer doesn't have to be smart about it, but dumb enough that the professional doesn't need a new degree to make it. For professionals, it's a, "Mix once," system, for consumers it's a, "listen anywhere," situation.
