Cena ok 870$ w Chinach, bywają promocje (-11% 770$),  wersja bez „U” jest tańsza

Nieraz można kupić także bez karty USB, za kolejne 50$ taniej

Gościł w moim systemie bardzo krótko (parę godzin). Brzmieniowo nieco słabszy od LKS Audio MH DA003 i tańszy. Różnica w cenie oddaje dobrze różnicę w brzmieniu przy podłączeniu DAC na wejściu cyfrowym. Przy wejściu USB różnice są ze względu na zastosowanie Amanero COMBO w LKS, który zwykle przewyższa sonicznie XMOS w chińskich DAC. Choć niektórzy umieją z chipa U8 XMOS bardzo dużo wycisnąć (patrz włoski M2Tech). Regulacja głośności to tylko gadżet, bo raczej nie da się nią sterować końcówkami mocy bez utraty jakości.
