Why is Sony Digital sound more like vinyl?

I have had Levinson, BAT, ARC, Wadia, Meridian, Denon etc...players..and the top ones, yet when I purchased a Sony scd-XA777Es I was touched in a way none of the others could! The one thing in common with the other gear was Burr Brown DAC's. Also, I have come to believe that RCA (single ended)connections are more musical. Most of my gear has been balanced...when I went all single ended...ah!!!...music like when audio was new!! Lastly, I have found that if CD playback levels on a preamp rise quikly with low volume settings...musicality and low level detail is lost. Perhaps others out there in Audiogon land have pondered my musings...or maybe I've got way to much time on my hands!!
