Currently I'm using a Yamaha RX receiver and just Bose ae2 headphones and an exstension cable but I plan on upgrading the headphones my question is will I need an amp if my head phones are strictly for gaming and movies? And do cables matter? Would I lose significant sound qulity with a head phone exstention? nd I've been recommended some gaming phones but i wnt just a dedicated audio set Ny suggestions? And if Nyome has any experience are some receivers better for headphones than others?
