I listened the the DSJ. I don't know about the whole burn in concept. This is a digital device and any thermal stuff seems minimal (at least from my engineering background). I should have eval'ed a little longer.
1. Moving to a newer platform made me send it back.
2. Wanted an integrated (amp) solution.
3. Wanted room correction (Lygndorf, NAD).
4. Although, Roon's DSP may make #3 moot..
Still searching for a single one box streamer.....
