Any thing more expensive than the SMSL Su1 (80) will only yield marginal improvments. Or if you want something that sounds slightly more analog, you can get the Shiit Modi 5+ with the AC power plug for $189. For example, I just upgraded my SMSL Su to a $320 Fiio K13 R2R dac and its hard to hear the difference, despite having audiophile Elac UBR 62 speakers and a clean Class AB amp.
