i suggest leeperry go and listen to some of these upsampling dacs as many of them sound very sweet. Upsampling doesnt increase aliasing at all; downsampling leads to aliasing. learn your stuff pls. Dont post those THD graphs, because theyre stupid. Listen to the music not a graph. If you're that concerned about such low THD ruining your music, stay away from tubes, stay away from vinyl, hell, stay away from headphones, cased speakers. In fact, dont listen to music at all. audiophile-grade equipment is generally from companies that dont just throw-in upsampling so they can say "we have 9001 mhz sample rate!11" its generally to assist in making the DAC/whatever sound nice because that is what will get them good reviews and repeated customers.
