These are basically new models, so they do deserve new names. The 5.2-channel DTR-20.3 is rated at 90 watts per channel. The 7.2-channel DTR-30.3 bumps things up to 100 watts per channel, with the 7.2-channel DTR-40.3 offering 110 watts. Last, but not least, the DTR-50.3 7.2-channel receiver is rated at 135 watts per channel.
All four products feature THX-Select2 Plus certification, as well as networking and USB capabilities that were previously only available on 2010's DTR-40.2 and higher models. Some of those features allow listeners to tap into music through a connected portable, or via web radio and network-connected computers. Preformatted service packages include Mediafly, Pandora, Slacker, Napster, Rhapsody, vTuner, and SIRIUS XM Internet Radio. The DTR-40.3 and DTR-50.3 also feature Last.fm as an exclusive.
On the video side, all four models include the Marvell Qdeo 4K (3840 x 2160 pixels) upscaling processor, with the DTR-50.3 packing in the IDT HQV Vida VHD1900 processor and ISF calibration capabilities.
