The Onkyo TX-NR708 is a lower-end A/V receiver comparable to the Onkyo TX-NR808. While both units support 7.2 channel audio, the 708 only allows for a powered Zone 2 or a Zone 2 line out while the 808 allows for a powered Zone 2, along with pre-outs for Zones 2 and 3. Otherwise, the TX-NR708 and 808 support the same broad variety of devices and formats, including: 7 HDMI inputs and 2 outputs (V1.4a repeater), THX Select2 Plus Certification, USB inputs, iPod/iPhone compatibility, TrueHD/DTS-HD decoding and a PC input as well as HD, XM, SIRIUS and Internet radio, DLNA streaming and WiFi/Ethernet connectivity.

The TX-NR708's 7.2 channel audio is supported by Audyssey equalization and Audyssey MultEQ room-correction for top-quality audio reproduction when paired with a high-end sound system. When paired with its extensive audio device compatibility (CD, iPod/iPhone, DLNA streaming, satellite radio) and audio format compatibility (MP3, WMA, WMA Lossless, FLAC, WAV, Ogg Vorbis, AAC, and LPCM), the TX-NR708's audio quality proves particularly useful. Of course, the TX-NR708's variety of HDMI 1.4 inputs allow for interfacing with any HD device, such as a Blu-Ray player, as well as 1080p video upconversion from nearly any source by Faroudja DCDi cinema.
