Questyle CMA400i
Publié : 10 févr. 2018 16:10
Voilà un ampli/dac relativement accessible en AKM4490, bien fini et compact. Il a la particularité d'avoir un sortie 2.5 dédié aux intra, il est réellement symétrique sur la partie ampli des sortie 2.5 et XLR4 mais offre aussi un 6.35mm plus classique ! Un bon choix pour ceux qui veulent profiter de leur intra ou casques en écoute de bureau
