I bought the POE+ HAT on visiting my dad because his WiFi struggles with DSD512 with an RPi4.
So when everyone is asleep and he wants to use headphones he can pull out this little stack (double sided taped together) and stream DSD512 without issues.
Its a 10m ultra thin Cat 6 UTP cable that goes from TV furniture to the coucb - very light and flexible cable carrying both DSD512 and power for the Pi and the DAC/Amp
When not listening it all just hides TV furniture cupboard
