For less than your budget, the Bel Canto e series is worth a listen. I still run my DAC3.5mk2 with VBL and Reflink (was sphile class A until replaced by Bel Canto Black EX also class A) but hope to sell soon to get a higher end chord. The DAC2.8 on agon is probably decent too but maybe not in the same level. Don't forget how important all the cables are, they can really change your sound.
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.
