So looking to get a 2.1 amp as the fosi bt20a pro I have does not work well for the the sub out. Saw a few options out but seems like for under $200 the douk d1 and the rsl ia255.1 are good options with a proper HPF and work with a active sub. Also saw the SMSL A50 pro, douk a5, fosi bt20a max, etc. Are there any others that I may have missed that would be good options beyond those 2?
 
allow for dac
What do you mean by that?
Aside from that, I recommend spending more for the WiiM Amp. Remote control, so nice! Can hide it away, so nice! And it freaking bloody just WORKS, wow I select it from my phone and it turns on and plays. Lovely! Plus more installed base and perhaps better resale eventually.
