I've recently bought sennheisers 599 and the sounds is quiet compared to my previous gaming headphones. I am stearing away form the gaming brandig to glorify products, and strive for raw audio quality. With this being said, I have done some research and it seems that my headphones do require an Amp ? Im not 100% sure so i would like some help with this. Simply put, do i require both DAC and Amp, or amp/DAC alone, and if so which one to pick for it to be sufficient for my headphones. Or perhaps i should go for a sound card along with it (or perhapd only a sound car) ? Any advice and help is greatly appreciated as I dive into the whole audio world. Thank you in advance ^^
