1. **No Built-in Ethernet Port** Unlike many competitors, it **relies solely on Wi-Fi for internet connectivity**, which can be slower and less stable than wired Ethernet. This may affect streaming quality in some cases.

2. **Limited HDMI Ports for Gaming** While it has **four HDMI 2.1 ports**, only **one is an eARC output**, and the others are standard HDMI 2.1. If you have multiple gaming consoles or 4K/120Hz setups, you may need an **HDMI switch or splitter**.

6. **No Built-in Phono Input** If you have a turntable, you ll need an **external phono preamp** since the SR770U lacks a direct phono input.

7. **Limited Upgrade Path** Marantz has **discontinued some of its higher-end models**, meaning firmware updates and future compatibility may not be as robust as with brands like Denon or Yamaha.

8. **No Dolby Vision Pass-Through** While it supports **4K/60Hz HDR10**, it **does not pass through Dolby Vision**, which may be a drawback if you own Dolby Vision content.
