I personally didn't like the 39. They don't use Burr-Brown Dacs inside. Why don't you consider a resolution audio cd55, Sony SCD-777 with another DAC or Mod, a theta gen 5a with a theta miles as a transport.
Better yet keep your Marantz CD as a transport and use a Pass Labs D1 dac. It has volume control (so you don't need a preamp).
