VARIAS PREGUNTAS:

- A la espera de que salgan los nuevos receptores A/V con HDMI 1.3, mi pregunta principal seria si aparte de este receptor necesitaria algun tipo de amplificacion, como una etapa o algo asi (en este aspecto ando bastante perdido).

- Lo segundo seria que traseros os pondiais para este equipo.

Muchas gracias
