What is so shocking? Because 150 is easy to listen to, musical and smooth.
He didnt say its better, but he says he enjoyed the 150 more than the 220 and Im ok with that.
As I said...everyone’s ears are different. For me...the DX150 wasn’t anything to write home about compared to the DX200, which was its big brother. Then the DX200-Ti came along and claimed the top slot as iBasso’s best release. A year later they released the DX220 which basically took the DX200 to a whole new level. My point is that everyone hears differently...but by all accounts the DX150 is very far behind the DX220 in the components department and the sound quality department.
