Why not more wireless connections?

Why not wireless connections between sources and amp and between amps and speakers?

The big fat wires normally connecting amps and speakers have to transmit power measured in tens or hundreds of Watts.  We are talking microwave ovens worth. by comparison, and you do not want to accidentally cook something in the radio beam, like a bird or your head.

Wireless data transmission over short distances usually needs only tiny amounts of power.  Many applications run for months or years on a single button-cell power source.

The only way to get rid of the amp to speaker wires is to put the amp(s) in the speaker box.

But you still need to run mains power so wireless is rarely actually wire less.

I agree with 'wire everything you can'.  With one exception in my case :).  My REL Carbon Limited subs run wirelessly on REL's Longbow system.  Why?  I had node (booming) issues with the subs in traditional (easily wired) positions.  I found with the wireless, I could move the subs around to find their best positions.  Turns out it was all the way to each side and asymmetrical.  I have a basement with odd wall shapes.  In this case, I achieved better sound by moving the subs to spots where wires were difficult at best.  From Tone's review of the Carbon Limiteds:

Finally, you can connect to the Carbon wirelessly, using REL’s Longbow transmitter, featuring the same functionality and inputs as the ones on the rear panel of the Carbon. This eliminates the long cables from amplifier to subwoofer and has a range of about 45 feet

My Auralic Aries Streamer can also run wirelessly, but it is most definitely wired.

all the usual reasons that wireless is convenient but inferior.  Slower speeds, more dropouts, much more jitter and therefore queuing demand (although jitter is filtered by your bridge), and a very noisy transmitter receiver, made worse by high usage/loads.

For most it probably won make. BIG deal but if you are chasing th best possible and have a really good system, the small effort is worth it.

There are times when convenience is useful.  It is never paramount.  I don't stream, I've got more LP's and CD's than I can ever listen to.  When not listening intently I prefer as much silence as I can get, and that includes the AC and the rooftop exhaust fan.  When I listen I focus on the sound, on the music.  I just finished listening to an album of stuff from Zimbabwe in the 80's. Last night it was Carl Nielsen"s Sixth Symphony.  I listen to these things like an explorer, always discovering new stuff.  Having background music in a car makes me crazy. Bottom line:  what other people do is fine with me but that's not where I am. If I had all my equipment hardwired within one box that is what I would do.  I'm not going to send the music to the speakers by radio.  I'm not going to take an analog signal. digitize it, then reassemble it. For internet radio, sure.  Otherwise, life is too short. I'm not arguing against convenience.  Sometimes that is necessary.  But to me, throwback as I am, the very concept of a server is anathema.  I know that stuff sounds pretty good, or can.  But joining the digital milieu is not my gig.  My AirPods?  Good for noise suppression when they reroofed the house, or for calls when going for a walk. Hard to take the stereo with you!

Personally, I'm just a lot more comfortable with wires and cable that I can see as opposed to wireless, which I can't. I still have a landline in addition to my mobile. I like plugging in cables/connectors.
