[QUOTE="TypodCrowd, post: 14040776, member: 481126" I myself am a reference lover (I want my source and amp to be "perfect" (flat EQ, low distortion, no fancy crossfeed stuff) and then my load (headphones) to color the sound as I please. For reference audio, the price to performance ratio of the Odac/O2 combo is to die for. It's awesome and a very good entry/mid level combo. I still own one today (though maybe not for long so if you're interested, let me know ). It's not the most portable (dac is usb powered so it'll drain your phone, and the amp can only be better powered if you have the dac in a separate chassis), but it's amazing to use on campus for me for example. It's audibly very VERY close to studio reference gear, so I absolutely love it. If you're willing to spend a little more money, I'd say pick one of the trifecta: Bass/warm tilt: Chord Mojo Neutral/reference grade: LH Labs GO2PRO/GOV2+ Treble tilt: ifi Micro iDSD Black Label [/QUOTE] sorry, such a refernce thing never happned on the earth. any gear has colors and sounds diffrent. as KG said, "there is no such a thing as normal". and ANY headphone are already phisically EQed. accordinglly you have no reason to dislike EQer. 1EQ(headphone) x 1EQ(EQer) = 1EQ its simple equation.
