It only samples to 24/96. Meizu can/could go higher.....
Can someone more experience in reading these outputs comment?
It seems to have a lower noise floor compared to the Meizu Pro, but have more distortions at both the lowest end and highest frequency ends. Clips just below 100 mW. The multitone isn't as nice a Meizu..... Is my 'interpretation' correct?
Don't quite understand the THD + N ratio vs measured level bits....and the ISO noise part at the end.
Sorry I can't say much about those measurements but I can share my experience.
Just got the Ugreen HiFi Pro to be used mostly with an old linux laptop replacing a Sound blaster X-fi 5.1 pro that has terrible EMI noises and background hiss with efficient IEMS (Revonext QT5 and TRN MT1), plus not native support of 44,1 khz.
I can say I'm very pleased for now, very clean and dynamic sound with absolutely no EMI noise nor background hiss with my IEMS, I'v tried also in high impedance mode with the trick, more power but again no hint of hiss or EMI.
I don't usually listen at too high volume and with IEMS, 30% vol in low impedance mode and 22% in high imp mode is already at my limit of tolerance. My over ear cans (Senn HD599, Samson SR 850 and SR950) are all easy driven so no problems here again, but I can say I'm impressed that it managed to drive an old (not mine) AKG 141/2 600 ohms 98 db, I got satisfiyng lavel at about 75% of volume and decent dynamic.
It works fine with my Realme 7 5G smartphone as soon as you activate USB OTG in Settings.
Got it for 40€ direct from Amazon Italy, not super cheap but 3 days shipping and easy return in case of problems, worth the money for what I've seen.
