I somehow stumbled into this thread on a lazy Sunday afternoon and went over the latest 15 pages or so. I haven't been following Shiit and I don't have any intention to look into their products as I am pretty happy with my current set up.
Having said that I wonder why with all the "heated" discussion about warm up times and "leave always on" there has no one mentioned active temperature control ...
. If the parts and circuits need to reach a certain temperature to tune in and sound best, why not help the DAC actively to reach that state ?
That is not rocket science :

If Shiit isn't integrating something, just get two of these thingies and put them under the DAC
