Solid Marantz Pre/Pro with Minor Usability Quirks
This preamplifier replaces a long-serving earlier model and delivers good sound quality, including with multichannel music. It offers more channels than needed for a 5.1 setup, but such options are common. Setup and operation are complex, though Audyssey room correction helps. The remote lacks backlit text to match its backlit buttons, and changing settings on the fly requires navigating a clunky on-screen interface rather than using the remote alone. Routing all HDMI video sources through the unit to a single display output is convenient.
Pros
- + good sound quality
- + Audyssey room correction
- + convenient HDMI routing to one display
Cons
- − overly complicated
- − remote lacks backlit text
- − clunky GUI for settings changes

Big improvement, easy setup with preparation
The AV7706 is large and requires space, but setup is quick using the assisted process. Audio improvements are noticeable compared to the replaced device. Audyssey calibration via the app is straightforward and delivers excellent room correction, with changes recalculated without full recalibration. The unit is complex and requires study to learn. The Smart Select feature is limited, as it locks to a particular input when saved; per-input Smart Select would offer better flexibility. Overall, very satisfied with the preamp and its software.
Pros
- + Big improvement in audio
- + Easy assisted setup
- + Excellent Audyssey room correction
- + App-guided calibration
- + Recalculates changes without full recalibration
Cons
- − Large size requires space
- − Complex operation requires study
- − Smart Select locked to one input when saved
