I'm a newbie to audiophile, so sorry in advance. I will try to keep this short. I just bought the HD 800S along with a Fiio K5 Pro DAC/Amp and intend to use for gaming and also music. Will be plugging in the K5 via USB to computer and the headphones to the K5 with the 6.3 jack. Thank you for your help or even a link to a YouTube guide would be a godsend. 1. I've used Tidal before, but is there any recommendations for best quality of audio music streaming program to use from my PC? 2. Is there any program I need to use for best sound results? I've heard the default Microsoft sound mixer gets used and is crap. 3. Is the default EQ fine? Or should I get a specific program and just download some presets to use while gaming or music? Thank you!! 🙏🙏
