Not surprised you find 005 superior to dacs you compared it to. I suspect the first thing most hear with 005 vs previous dacs is it's high level of resolution, transparency, the manner in which Sabre chips utilized reason for this. My 005 remains in main system over a number of years, and this with well over $40k spent on other upgrades since 005 in main system. Only now that I've maximized every single other link in chain have I come to contemplating purchase or audition of another dac, the only dacs I'm considering are Mola Mola Tambaqui, EMM Labs Da2 V2 or Playback Designs MP8, all far more expensive than 005, anything else I'd consider more of a lateral move.
While 005 highly resolving, transparent, can present high level of realism in very high end systems, this means timbre, tonality, soundstaging, imaging, dynamics, especially micro dynamics all first rate. Based on my research I'd expect dacs mentioned above would retain or exceed extreme high levels of resolution, transparency of 005 surpass with sense of refinement, ease. In spite of many upgrades over years with 005 I have yet to find it to be cause of fatigue or incapable of presenting sense of live performers in room, only the audiophile in me creates the desire to upgrade.
005 burn in should never really be a problem assuming you like initital sound, I only experienced continual improvement over time. Maximizing every single aspect of streaming setup extremely important with 005, highest quality server/streamer one can afford, high quality linear power supplies on every single component, AC, DC, ethernet cables all important, power conditioning, I also do optical conversion. 005 high level of lresolving/transparency will expose virtually everything up and downstream in system so it can live for long time in most every system.
