Oppo ppl make a great machine but the other brands you mention are leagues ahead of it. Esoteric, Luxman, Bryston.
And how about for video?
I feel the need to repeat myself. The Oppo UDP-205 is an **absolutely essential** piece of gear in any serious A/V system, regardless of how much better any other brand is (from a CD/SACD only perspective and in keeping with the thread/OP question). My suggestion, buy both, a UDP-205 and whatever else.
