You may never hear a difference. Consider yourself lucky in some ways. The Oppos are decent machines and as good as many people require.
My suggestion is to stop thinking about it, leave the dac in the system for a month and then take it out. Sometimes, the benefit of a new component can be better judged when removed from the system after listening. But I think you also see that reviews or buzz about a component it doesn't mean you will like it better than what you have.
