I'm in the process of building an Aikido OTL headphone amp and thinking of add a pair of VU meters, just for the look.
The driver board I intend to use is this one: https://www.ebay.com/itm/1668490787...HbusGwtRI-&var=&widget_ver=artemis&media=COPY
My question is whether I should connect the meters to the RCA input (fed from a 2Vrms output DAC) or headphone output?
And of course, most common question, does these meters affect the sound in any way?
Thank you in advance.

Take the RCA input, it is neutral. The volume potentiometer influences the display on the headphone output. Apart from being a nice, optical gimmick on a headphone amplifier, such displays have no other useful value.
