Nativ Wave is built for the best headphones. It incorporates a balanced amplifier with an advanced 100% solid-state topology and a high-speed buffer with a slew rate above 2000 V/ms to prevent odd order distortion anomalies. https://www.indiegogo.com/projects/nativ-high-res-music-system-touchscreen-control#/

Slew Rate Limitation in an Operational Amplifiers -A real op-amp is limited in its ability to respond instantaneously to an input signal with a high rate of change of its input voltage. This limitation is called the slew rate, referring to the maximum rate at which the output can be “slewed”. http://ingenuitydias.blogspot.com/2015/05/slew-rate-limitation-in-opamp.html
Classic Gainclone amplifier based on LM1875/LM3886/LM3875 (...) IC's (all amplificiation circuitry on a single chip), you would be surprised how amazingly good these can sound, courtesy of short signal paths, low capacitance, big corporate R&D budgets and advanced manufacturing, they feature low distortion and very fast slew rates.
