By "flexible" do you mean capable of playing multiple formats or have other capabilities? If you are looking for a universal player, the Oppo 105 is certainly hard to beat, particularly with streaming and a great DAC.
If you are only playing red book CDs, I think a dedicated CDP will sound better. There are some great used options that you can find for around $1k.
