The price argument does not fit, it's common for a product to be delivered works flawlessly and regardless of price.
If I can not produce the required (usual) a quality product at a certain price, I have to calculate the price new or rethink my business model.
But apparently it has become normal to buy unfinished and to cheer
The price argument fits for me. DX50 plays all the music I choose to load on to it and sounds better than anything I have heard near this price. I don't know what more I want iBasso to fix apart form gapless which is not a deal breaker for this quality and is easily sorted.
iBasso are a relatively small company as most buyers are aware of. The produced a product that plays music files and makes them sound incredible for a price that cannot be matched at the moment in my opinion. Any firmware issues are fixed quickly.
What exactly can you not do with your DX50 that you would like to do but are unable to? It is afer all only music player.
Maybe you should scrap your business model and statrt listening to your music.
