I love this processor...
After years of high-end receivers, I finally took the jump into separates, and I love everything about the 7706. I've paired it with a 7-channel McIntosh MC-207 amp for the mains, and a Marantz 7055 5-channel amp for the Atmos speakers. Running all Audioquest XLR interconnects, they bring life to my Paradigm Reference and Klipsch Atmos speakers. It has dual subwoofer outputs, so clearly I needed to invest in two SVS PB-16 Ultra subs. (I can rationalize just about anything, lol.) Next up: Either replacing the Paradigm Reference with B&W 800 series, or setting up a Zone 2 stereo setup with 800 d4's and McIntosh power.

Impressive Upgrade
Swapped my AV7702 for the AV7706, along with a new projector and XBOX Series X. Still waiting on the Sony 5000ES projector but I was very pleasantly surprised to the improvement in audio quality on this preamp. I purchased it for the updated video features, and cannot wait to see the results!

So glad I pulled the trigger!
After finally deciding to ditch my Onkyo Preamp, I’m so happy I did. A major step up in quality, sound, and functionality. Enjoying this preamp more each day!

Audiophile DACs, bass management, and 7ch inputs
I bought it from eBay as open box. It surpassed my expectation with its audiophile grade stereo DACs, sounds better than Oppo BD105 DAC. I appreciate the 7ch direct analog inputs for multichannel SACD and the nice bass management present features. Remote could be better.

Leaves much to be desired.
This pre-pro has 4 ways to control and configure but neither of them work 100%. The remote control is worthless. The onscreen display has never worked with my Sony xbr85x850g Bravia. The "2016" Android app can only control and configure half of the menus. You have to pay for the app to configure timing through audessey. You can access the web page of the device to configure other aspects. Time to update your Apps Marantz get rid of the dead weight app developers and hire a team that can develop a single utility to perform all features from an single environment. The app is something I'd expect out of a budget product not a high end $2500 prepro. I would like to be contacted personally to discuss the lack of management and configuration capability.
