Truthear x Crinacle Zero:RED bass difference

[timer1992]

Hello everyone, I just received this new pair of IEM today and thought I'd do a quick measurement. Here is my setup:

• GRAS 45CA with RA0045 and KB501X pinna
• APX525

However, the test results revealed some differences in the low-frequency range compared to measurements conducted by others.
So, I'd like to inquire about your opinions. Is there a chance that I might have overlooked something in my measurements, or could there be any other possibilities?
Thank you.

Is your amps output impedance is in the two digits?

Haven't measured mine, but it seems compatible to my experience. It's plugged into an RME Fireface ucx-2, I can hear the bass is bloated and slow, the mids are recessed and the highs dip too much. The 7Hz Zero 2 is much better comparatively connected to the same (low-ohm) interface. Is there big unit variance here or did they change the voicing?
