We recommend this DAC & amplifier for all our headphones, and for any other headphones as well.  The FiiO KA13 offers unrivaled performance for its size and price.  Even for use at your desk at home, the KA13 does a fantastic job at ensuring audio is decoded with the least possible loss.  With two high-performance yet highly efficient CS43131 DAC chips, and two low-noise SGM8262 op-amps, this truly "dual-core" golden combo brings excellent performance. Rediscover your music collection again with the KA13.  With support for 32bit/384kHz PCM and DSD256, the KA13 is capable of highly detailed sound.
