Also as part of the raft of announcements at CEDIA last week, Marantz has launched the latest edition to its line of preamp/processors, the AV7705. The 11.2-channel processor is the first of its kind to introduce the new IMAX Enhanced feature, intended to enable experiences with a ‘a new level of quality in immersive sight and sound.’ The IMAX Enhanced program is supported via free firmware updates.

“Marantz sets the standard for music lovers and critical listeners around the world, so everything we do and build starts with ensuring we’re providing optimum fidelity for beautiful, natural sounding music,” said Emmanuel Millot, global brand director at Marantz. “Fans of Marantz technology will see familiar features, like HDAM technology and the ability to decode lossless files with exceptional signal quality. However, the AV7705 does more than recreate music; it provides the ultimate home theater experience. We’ve integrated brand new IMAX Enhanced technology, support for the latest audio and video formats, multi-room audio functionality— including Apple Airplay2—and several options to make custom integrators lives easier than ever.”

The IMAX Enhanced AV7705 pre-processor leverages the latest technology from IMAX and DTS that promises to set a new standard for image, sound, scale, and content quality. The technology is intended to produce clearer pictures and brighter images alongside ‘immersive, heart-pounding’ audio. The Marantz AV7705 also supports the 3D audio formats (Dolby Atmos, DTS:X, Auro-3D). The pre-processor also includes Dolby Surround, DTS Neural:X, and AURO-MATIC up-mixing.

Real Name
I'm a Marantz customer and fan in general but this sounds like snake oil. I found the below in a preliminary review over at Digital Trends while trying to figure out what "IMAX Enhanced" really meant.

As for what IMAX Enhanced brings to the table, we haven’t yet had the chance to try it, but it promises “a new level of audio and visual excellence.” Everything else we’ve seen under the IMAX name has been fantastic, so there’s no reason to expect otherwise here.

I know nothing of IMAX in the Home Theater space. Are they trying to take on Dolby?
