Úvod do zvuku – první díl megatestu karet Asus Xonar | Kapitola 5
Seznam kapitol
Zvukové karty ASUS Xonar již zaujaly v oblasti ozvučení své pevné místo a to právem, jelikož jsou prostě dobré. Uživatelé to vědí, mají je rádi, a tak jsme se podívali podrobně rovnou na všechny jejich modely. Celkem devět karet tvoří současnou nabídku interních zvukovek ASUS, přičemž některé jsou v PCI a jiné v modernějším PCI-E provedení.
