Sony has unveiled two new high-end receivers, with the STR-DA5600ES and STR-DA3600ES hoping to build on the reputation of the company's ES.

Both the STR-DA5600ES and STR-DA3600ES offer 3D pass-through on HDMI, Digital Cinema Auto Calibration, DLNA with a four-way Ethernet hub, and 1080p upscaling.

"The two new products enable even better home cinema sound, plus state of the art features such as 3D pass-through, DLNA connectivity for networked audio and video and internet radio," states Sony.

"The 120W per channel STR-DA5600ES is built to produce top end audio quality and sound tuning," says Sony.
