Hi, newbie here. I am trying to install my new Purity's direct from my Av processor (Emotiva UMC-1) and get no sound at all. Do I need to go through the amp even though the signal will be cancelled? (I bought a 5ch. amp, Emptica XPA-5) Do I need to send a strong signal to the speaker to trigger the internal amp or I'm doing something wrong? Maybe buy a cheaper 2 ch. amp?
