Hello!Is there any who tested both X20Pro and UHD2000? Im curious about the sound quality.Im wonder https://trackeasy.fun/usps/ https://showbox.tools/ is it worth to upgrade because the sound quailty improvements? The other thing is how stable the actual fw of UHD2000? X20 pro has far more fw repairs than UHD2000, so Im afraid still not as good like th old one. Please share real expreineces not just opinoins based on specs. Thanks.
