Need advice on buying an DAC and AMP

[zAlymere]

I'm new to audio stuff and I'm currently using Fosi Audio Q4 on my PC and looking to upgrade my setup and audio listening.

The SMSL SU-1 is affordable that is why I'm considering buying this but I'm not sure what headphones amp to partner up with this DAC.
Could someone recommend me an affordable amp for this?

Also, is Topping DX1 or Topping DX3 Pro+ a better option than a stack DAC and AMP than I've mentioned?

Currently using Epos H6Pro, Aria Snow, and Crinacle Zero.

I appreciate any feedback.

I put the SU-1 with a Topping l30 II and it's amazing. The Drop THX is a great match, in low gain IEMs are excellent. The L30ii has more power though.

If you like combos, Fiio K5 Pro (single ended HP amp) and Fiio K7 (balanced HP amp) both are worth considering.
