I guess I'd mention 2 things: anything to do with cleaning up the power is most important: separate mains ring, proper connection to ground and good power cables and multi- plugs (I use Acoustic Revive RTP-4)
Secondly, a Schubert resonator like the Acoustic Revive RR77. The effect on smoothness, soundstaging and resolution never ceases to amaze me.
Most hardware on proper power supply is way better than expected and in my experience actual differences in latest generation dacs of decent quality are minor
