I am a casual gamer and music listener.
I listen pop, hip hop, rock mostly, i listen over long sessions i mention it cause i heard some combos may be fatiguing. As dt 1990 is single ended only i want something that covers that too, cause usualy se is weaker than ballanced.
I appreciate all the help i can get :smiley:
