"Also you can't possibly fit a good sounding DAC in such a small format."
Have to disagree with you, there.
DAC performance can be measured objectively, and there certainly are very small DACs that perform extremely well. Remember that as portable ones run off DC they don't have to do as much space-consuming fiddling with AC input as desktop DACs do.
https://www.audiosciencereview.com is a good source for consistent objective testing of DACs and amps. Look specifically for posts by amirm, the site owner. He's measured several small DACs with very good performance. In fact, partly as a result of the reviews on that site, I stopped using complicated desktop DAC/amp setups, ditched the iBasso DX200 portable DAC/amp I got...and switched to just using an LG V20 smartphone as my source. All the phones with LG's "quad DAC" have very good measured DAC and amp performance and provide up to 2V of power, which is enough to drive almost all headphones to painful levels.
