I would try to listen to a few DACs if possible. Not sure I would buy a digital component that is 10 plus years old. What's your budget?
Battle of the Older DAC
Would this be a simple choice for you?
Looking at upgrading my DAC and at similar price points have options of an Auralic Vega (2013) and a Schiit Yggdrasil OG A2 (2018?)
I have heard the Auralic and it is impressive, but the reputation of the Yggy looks solid.
Would be keen to hear from anyone who has experience of both or if the choice is clearer that it appears to me.
As ever, would love to hear your thoughts.
