Best DAC-headphones combo for A90 under 2k?

[slave of JESUS]

I use a Topping d10b in a lot of Amps and it's terrific. If it was me I'd get that and the Hifiman Aria together to keep in budget, used but nice I see them on eBay for under 1k. Just get the V3 stealth, they made some improvements. I just sold a pair of HD800s two days ago, and they're good but every day I like the Hifiman Ananda better. I bet if you got the D10b and Ananda you'd be really happy and we'll below budget.

Thank YOU A LOT SIR!
