While the Pi4 can burn lots of power, streaming audio isn't going to
need high performance. I am running a Pi4 with IQAudio digiAMP+ hat
stacked on the back of the official display.  Cooling is just the stick
on heatsink that the pihut sell.
Reported Pi temperature is 50 - 55 degrees C while driving local
speakers and a separate bluetooth speaker simultaneously.
I can live with that

I wouldn't be using a Ras Pi - I'll be using a Nanopim4 v2

The Khadas just plugs into the usb port

Over on the rpi forums, users  recommend vanilla SSD sata over the M2 as
the rpi cannot utilise the full speed of the M2

USb boot on the rpi4 is now at "stable"

There a lots of options for mounting and cases, this is just one

I think the Pi group have lost their way a bit - removing the full size
HDMI for one and adding two minis was a mistake in my book. Who will
want to run a dual monitor setup on a pi ? and yes I agree they run a
lot hotter than the other models. I've used a 3b+ as my LMS server and
player for years now without any problems. I'd be interested to know how
you use a Khados tone bar as I would like to try using another SBC (
FriendlyElec Nanopim4 v2) as a server and player and as none of the pi
DAC hats will work on them maybe a Khados is the answer. My motive for
using it is you can fit a NVME M2 SSD drive via a hat and that would
enable me to get rid of my external USB drive and reduce the clutter of
wires. Does the Khados simply plug into a USB port ?

Because a Pi4 is terribly hot compared to previous models. I ended up
with the Flirc case, which is both a case + heat dissipator and am very
happy I did so.
I believe that using a HAT would mean, at least, the raspi processor
slowing down to avoid heat damage (and for similar performance, then I'd
rather use  a Raspi 3)
