I did direct volume-matched rapid A/B comparisons of entry-level (under $100) to much higher-end (three to four figure) DACs I owned via the Schiit SYS. You may be surprised how little the differences were. In many cases, there was no audible difference! Fulla 2 vs 2Qute...UCA202 vs Mojo...etc. This was comparing the DACs with speakers. When I compared DAC/amps driving headphones, the differences were larger. (Primarily because of the different amps.) To anyone comparing DACs: Don't judge them through casual listening alone. I thought the differences were larger than they actually were due to not testing properly via the method above.
