Rogue DragoN or Bel Canto Ref600 M

Considering moving to either a Rogue DragoN or Bel Cato Ref600 M’s.  Current equipment: PrimaLuma HP Integrated, PS Audio Direct Stream Sr. DAC and Joseph Audio Prospectives.  Initially will use PS Audio as pre.  Looking for more headroom while maintaining classic tube like sound stage and move to US based equipment.  
Would like to hear others opinions / experience with Rogue and Bel Canto etc.
