Druhý díl megatestu zvukovek Asus Xonar – vyhodnocení | Kapitola 9
Seznam kapitol
V minulém díle našeho megatestu jsme se podívali na první čtyři zvukové karty Asus Xonar. Prošli jsme si situaci na trhu, ukázali trochu teorie a naměřili mnoho a mnoho hodnot. Dnes se podíváme na poslední testované karty a především vyhodnotíme všechny grafy. Takže – která zvukovka Xonar je právě pro vás?
