Best Praise
+17 pts“I would actually go the middle route and get a good dac/amp around 100 bucks like the FiiO K11, because diminishing returns hit HARD after that price point, and then spend the rest of your budget on headphones.”

ViewTop Criticism
+5 pts“what amp did you use? k11 headphone amp part is trash, as a DAC only it's pretty good but they got KA15 R2R coming out, portable and less power but that is going to sound better”
