Fully agree with you!I think the most important consideration is for the meter to not introduce any audible noise or distortion into the audio chain.
Yes, this was/is one of the indispensable "conditions" for my DIY on 12-VU-Meter Array in my audio project.
The IEC 60268-17 compatibility of ballistic behavior of the VU needle should be another important "condition" at lease for myself (The rise time, defined as the time it takes for the needle to reach 99% of the distance to 0 VU when the VU-meter is submitted to a signal that steps from 0 to a level that reads 0 VU, is 300 ms. The overshoot must be within 1 to 1.5%. The fall time is the same as the rise time, 300 ms.).

All the VU meters should be in the end of the signal chains and definitely no throughout signal from VU unit would be utilized for further audio processing/listening purposes in my audio project.
