I was able to home demo the +player for several weeks, however I was only able to AB it against an older Accuphase and newer Lumin X1 DAC. I preferred it over those two for realism as well as the other observations above.
The only knock is with the audible, mechanical click produced when it switches signal paths for different bit rates. Not a deal-breaker as the results are worth it, and depending on how far away you sit, it might not be a "thing" for you. YMMV
