Both 9.2 channel receivers are THX Ultra 2 Plus certified.
The DTR-80.3 and DTR-70.3 receivers from Integra are fairly similar in their feature sets. The 80.3 pumps out 145 watts per channel while the 70.3 only offers 135, and each uses a different power supply but aside from that they're not terribly different.
You'll find Audyssey DSX, Dolby ProLogic IIz and DTS Neo: X technology that upscales your sound up to 11.1 channels. They also give you the ability to stream from online sources like Spotify, Pandora, Sirius and more. You can also play a variety of files stored on your home computer.
Integra's new receivers are no slouch in the video department either. They pack HQV-Vida video processors and Marvell Qdeo 4K upscaling. You'll get enhancement of not only traditional content, but cleaned up streaming content as well.
Both receivers will be available soon with the 70.3 coming in at $2,000 while the 80.3 runs $2,800.
