It is incredible that something this small can sound so good.In my opinion, i dont think so. Yes w4 is good. But if you compare with Flag ship tier DAP.... not fair for W4. It better than Mid range DAP. For example, i have test with fiio m11 plus, hiby r6 pro and shanling M7. P/p w4 is better than that all and w4 is so convenient for traveling or go to the coffe shop
I am sure it will be a success just as W2 is.
