Wadia 861se with GNS vs Esoteric or Emm players

Hello, I'm ready to send my Wadia 861se to Great Northern Sound in the next month for their Reference upgrade. Would I be better off selling the 861se and finding a used Esoteric X-01 or Emm Labs transport&dac. Having SACD might be kind of nice. Has anyone compared these three? Thanks! Stan
