For what it is worth, I use one this" VU meter" , but as a power meter. It is hooked up to the pre-out of my integrated amp, and calibrated so that 0dB is max power out of the amp. I am not sure if it causes any distortion when hooked up- will need to measure that one day. I think they have a newer version on Amazon. I have two other LED power meters I built using LEDs (I have this thing for LED power meters) that measure directly at the speakers.
