You’ve received some very good recommendations and you can’t go wrong with either Vandersteen or Oppo. Given your room size and musical taste I would offer the following combination as a option.
1 Marantz SA 8004/8005 CD player, Well engineered (good power supply and analog output stage) very solidly built chassis and high quality sound. 1200K new.
2 Tekton Lore speaker, higher sensitivity and 8 ohm load (easy to drive) well designed. 1000K new.
3 Coincident Dynamo MK II amplifier, very well made and offers exceptional single ended sound quality. Can easily drive the Tekton Lore. 1500K new. This leaves money available for necessary cables. I believe that these combined components would provide a very lively, dynamic and organic presentation with beautiful tone and emotional involvement. Very good value purchased new and obviously more so if bought used.
Good luck,
Charles
