Agree, depends on the headphones you have whether the amp section will be okay. The amp section is good technically but just doesn't sync well with certain headphones. Fostex TH-X00 series are such headphones that just don't like the amp of the ADI-2 DAC... they sound thin and overal lacking with it, loosing their fullness and bass. The Campfire Audio Cascade syncs really well with the ADI-2 DAC on the other hand and doesn't like the amps the TH-X00 prefers. I didn't really get the ADI-2 DAC for it's amp section being it's for my STAX rig.
