Asus Xonar Essence STX DAC PCM1792A de Texas Instruments


Si comme moi , vous en avez marre d’avoir un son de merde sur votre PC, voici une carte sympa, pour un peu moins de 200 €.

Mais pour ce prix , j’ai eu nn Technics SU 3400 et un Marantz PM 200

Pas mal de gadgets, mais bon, on est pas obligés de les utiliser et les perfs sont au rendez vous pour un prix plus abordable que les cartes son pour la MAO.

Enfin je ne l’ai pas encore achetée, je prospecte. Compte-rendu si achat.
