This is my daily driver IEM DAC/Amp when I'm at work. This easily drives planar or dynamic IEMs. Definitely not for inefficient headphones. Very clean R2R sound for low cost. Sound signature is very neutral. I would recommend this. I also recommend using the 4.4mm balanced plug since balanced is superior for noise elimination and power.
ShredderAgree, not for sensitive headphones - audible noise in CA Andromedas, for instance. But this is 100% fixed with an iEMatch, highly recommended for sensitive IEMs.
