The W2 has been measured properly. No Dap can compete within this price range with W2. Afaik, DAPs is usually not worth it compared to buying a cheap Android phone+dongle. Most DAPs=old android phone with built in dac /amp you pay premium for.
Here is an update for the Luxury and Precision W2 . Need to translate yourself. https://card.weibo.com/article/m/show/id/2309404608789365260508#_0
This W2 seems incredible so far!
Im using dwsktop based and on my signalchain it says 64 bit floating. Hmm. Im stuck between topping l30/e30( each cost 175 usd in my country new), E1da or Khadas tone 2. Not easy when i cant try first. Want it to be a little "futureproof".
