So i just saw the 6xx's go on sale and i pulled the trigger and theyve already shipped... but right now I'm so torn between the 6xx or the 58x - this is my first run at an audiophile set of headphones. My main thing would be using them for gaming, but i do love music too - music to me is everything. With that said, primarily they'd be used for gaming. I own a sound blaster g6 which is a virtual 7.1 32-bit/384kHz, 130dB USB Digital Audio Converter (DAC). It also boasts Dolby Digital decoding, virtual 7.1 surround sound which both the 58x or the 6xx's would probably benefit from. All in all can someone help me figure out whether ive made the right choice?
