I agree about everything you said here. The soundstage, details, separations...etc... were the reason why I moved on from WM1Z
I do not understand people who would claim DX220 or even Dx200 to be mid-tier. The only way I see it is that they either are trying to damage Ibasso brand and images, or they are lying to themselves as Biased toward their favorite brands....
IMO, DX220 is completely high-end, competing toward other brands and products....except....very affordable which could be either a pro or a con. To me, Ibasso is an awesome brand with excellent customer service, the heart of enthusiasm, and excellent products at a realistic pricing
