Thanks for your answer. How close to the back wall can the TUK (since it has a back port)?Kanto rep here so take my biased advice with a grain of salt, but afaik LSX does not have auto-on via the wired connections. They turn on automatically via wifi or Bluetooth. I don't know if AVS allows external links but one reddit customer made a list of gripes/deficiencies of using LSX on desktop. Link here.
TUK was designed with features to make it work well on desktop - Low noise floor, USB input, headphone out, auto on/off that you can defeat it so it stays on all the time, LED brightness control. PM me if you have any specific questions.
