Yo creo que si, mira lo que dicen las caracteristicas.
"The TX-SR313 can decode Dolby® TrueHD and DTS-HD Master Audio™—two “lossless” Blu-ray formats that deliver a soundtrack identical to the studio master, so you’re hearing it exactly as it’s meant to be heard. The TX-SR313 also handles Dolby® Digital Plus and DTS-HD High Resolution Audio™. Dolby Digital Plus is designed to accompany HD video delivered via disc media, television broadcasts, and online content."
De lo que no habla y seguro que no llega es a tratar Dolby Pro Logic IIz.
Un saludo.
