Does the budget include the amp and preamp?
A couple of options there:
DAC + Preamp: https://smile.amazon.com/gp/product/B01N14SY65/
Amplifier: https://smile.amazon.com/gp/product/B077GWVHHN/
Some are available with tone controls as well.
Can also get an AVR which makes this much simpler and gives you good bass management options, necessary for a subwoofer. I suggest one with Audyssey XT32 and using the app to limit correction to 400-500 Hz. Paired with neutral speakers that won't need correction above that as you're listening nearfield - the room won't have a big influence and the direct sound will dominate.
