STR-DA6400ES, which casually streams high-def content over CAT5e, has finally nailed down a date to mingle with crowds in Europe. Just today, Sony has announced that the aforementioned model will be available this May along with three other new STR-DH receivers: the STR-DH500, STR-DH700 and the STR-DH800. The flagship model boasts 7.1-channel audio, DLNA compatibility, six HDMI inputs (alongside two outputs) and Digital Cinema Auto-Calibration. The rest of the crew ranges from 5.1- to 7.1-channel and are generally stripped down versions of the big papa. For more details on each (price notwithstanding), give that read link a look.
