The spec table (product details, image 28) and the noise panel (product details, image 10) give ≈1.4 µV / about 1.4uVrms (original: 约1.4uVrms); the JM98MAX vs JM98MAX 2 comparison table (product details, image 4) gives ≈1.3 µV for JM98MAX 2. The record takes the spec table value.

The SINAD panel (product details, image 9) says 108 dB SINAD (original: 108 dB 信纳比); the comparison table (product details, image 4) gives ≈110 dB for JM98MAX 2. The spec table has no SINAD row; the SINAD figure stays a fact only.

Product gallery, image 5, says 0.0003% ultra-low distortion (original: 0.0003% 超低失真); the spec table (product details, image 28) and the THD+N panel (product details, image 14) say ≈0.00035%. The record takes the spec table value.
