I thought this was about "room steaming", I'm a carpet cleaner and can steam clean any room you need!

Which cleaning chemicals make the room sound best? :music-listening:

Wireless networks don't have the bandwidth of wired networks and are less reliable. However, if you can get consistent bandwidth good enough for audio it should work fine. I've streamed HDTV over wireless without any problems, but I would rely on it.

When we move to the new house FIOS will be providing all new service. One of the "features" of the new DVR that also syncs to mini desk top boxes is the ability to transmit wirelessly. However, looking at their customer responses there is a high rate of dissatisfaction with the wireless connections. Granted the requirements for 4K TV are much higher than audio but I am still having the low voltage wiring guy install coax and ethernet at each position. BTW, if you need to expand wireless coverage you might want to check these access points.

Every room in our house has a gigabit hard-wired LAN drop.

Apples and crocodiles.

In audio, the digital stream handles a minuscule bandwidth (20kHz) and only two pieces of information (for each of the two channels) , frequency and amplitude.


Compared to 20kHz, visual bandwidth is 770THz. A 4K TV digital carries information for 4096 x 2160 pixels, with 16.7 million colors for each pixel and thousands of light intensities, all refreshed 60 times a second.

The point being, video broadcast is never true representation of reality and realize small degradation of the properties, unless the pixels stop refreshing.

So regarding my quote, I meant to say I would NOT rely on it.

Regarding Shashi's quote, HDTV at 1920x1080 takes about 6mbps per channel thanks to thanks to the compression capabilities of MPEG4. It is lossy, but I think the results can be stunningly good.

Regarding wireless networks for audio, I have been successful in configuring a wireless bridge to ethernet using a 5Ghz band (after finding a quiet channel), and it has performed flawlessly streaming up to 192/24 audio from Qobuz to an RPI4 based renderer. Absolutely solid and reliable. Had problems with noise using a powerline ethernet adapter. Just another perspective.

There is no one solution to everything. It's good to have choices.
