Appearance & Chassis Design

The D3 Plus used a predominantly plastic chassis, prioritizing light weight and practicality. In contrast the D6 Max uses a design combining metal alloy (aluminum-based) panelswhich improves not only perceived premium quality but also heat dissipation and rigidity. As a result, thermal throttling during extended continuous operation is less likely, making it better suited for always-on use at home.

The use of metal panels contributes both to cooling efficiency and appearance.

Wireless Communication (Wi-Fi / Bluetooth)

The D6 Max adopts a 2T2R Wi-Fi 6 configurationwhich significantly expands communication bandwidth compared to the implementation in the D3 Plus. This difference is especially noticeable in home networks with multiple simultaneously connected devices and in high-bitrate 4K/8K streaming. Bluetooth 5.4 is also adopted, contributing to more stable audio and external device connections and reduced latency.

  • Practical benefits of the D6 Max:Lower buffering rates and reduced latency during high-quality streaming, improved responsiveness for remote control from smartphones.

Wired LAN Port

Compared to the D3 Plus's 100Mbps,the D6 Max supports Gigabit LAN (1,000Mbps)In households with fiber or high-speed plans, wired connections are more stable than wireless, so for live TV viewing or environments with many simultaneous streams, this provides substantial practical benefits.

Stability in real use Sufficient for home use Advantageous for high-resolution streaming

Memory and Processing Performance

Both models use DDR3 memory, butthe D6 Max has a wider memory bus (e.g., implemented equivalent to 8-bit), designed for increased data transfer volume. This improves perceived responsiveness in app switching, concurrent app usage, and quick access to program guides. Additionally, increased capacity and faster internal storage speed up app updates and cache handling.

Remote & I/O

The bundled remote for the D6 Max is upgraded to a backlit air-mouse type, enabling operation in the dark and pointer control. This makes text input, web browsing, and fine controls within apps more intuitive. Power has been changed to USB Type-C, improving the versatility of power delivery.

Software and Features

Through software optimizations, the D6 Max enhances viewing experiences such as 168-hour (7-day) time-shift playback. This makes "missed viewing" more flexible and improves everyday convenience. In addition, high-resolution decode processing and app launch optimizations increase comfort in real use.

Video Output (Resolution)

On the video side, while the D3 Plus is limited to up to 6K support,the D6 Max supports 8K Ultra HDIn typical households, regular use of 8K content is limited, but if you already own an 8K TV or prioritize future-proofing, the D6 Max is advantageous in the long term.

Overall Evaluation and Recommendation

In conclusion, the D6 Max surpasses the D3 Plus in both hardware and software. In particular,faster wireless/wired communication, improved cooling, remote convenience, USB-C power delivery, and support for 8K outputare notable. The current D3 Plus remains a reliable choice and is "acceptable for the time being," but if you prioritize high-quality viewing, future update compatibility, or simultaneous use by multiple people, we recommend upgrading to the D6 Max.

Purchase guideline:
  • If you are using a 4K/8K-capable TV now or planning to replace your TV in the future → Recommend D6 Max
  • If stable viewing is sufficient and you want to minimize cost → D3 Plus is also reasonable
