I really want to add a pair of vu-meters to my Dac-9h ( something diy ), and i was curios if it's safe to use the coaxial output while using the headphone jacks. (i'm only using headphones)
Or can it have any negative impact doing that ? (from my test, it works to output to headphones and some active speakers over coaxial)
I was planing on using the TEK Active control module for stereo meters.
