The attention to musical detail and ability to hear into the recording this naturally is stunning!

    High performance headphones require a quality portable headphone player or headphone amplifier for best results. A cel phone will not play to satisfying levels nor quality. We highly recommend the XIAUDIO K DAC and XIAUDIO Broadway Balanced amplifier for Diana TC.
