Users consistently laud its exceptional sound quality, often describing it as transparent, detailed, and incredibly dynamic. A standout feature frequently highlighted is Lyngdorf's proprietary RoomPerfect room correction technology. Reviewers are genuinely impressed by how effectively RoomPerfect transforms their listening space, eliminating room-induced anomalies and revealing a much clearer, more coherent soundstage with tighter bass and improved imaging. Many consider RoomPerfect to be a 'game-changer,' elevating the listening experience significantly beyond what traditional room treatments or other correction systems can achieve.

Its versatility, including comprehensive digital inputs, HDMI connectivity, and integrated streaming capabilities, adds significant value and convenience, making it a central hub for modern audio setups. While the price point is acknowledged as premium, the consensus among owners is that the TDAI-3400 delivers exceptional performance and a unique feature set that justifies the investment, particularly for those seeking an uncompromised audio experience tailored to their specific room acoustics.

Know before you buy
RoomPerfect analyzes your room's acoustics using a microphone to identify and neutralize negative sound reflections and bass resonances. This ensures that the amplifier delivers a balanced, accurate sound profile tailored specifically to your room's unique shape and furniture layout.
Yes, especially if you opt for the HDMI 2.1 module. This allows you to connect your TV and gaming consoles directly to the amplifier, supporting up to 8K video pass-through while processing high-quality audio through your speakers.
Absolutely. The built-in media player is Roon Ready and supports Spotify Connect and AirPlay 2. It also handles high-resolution audio formats, including MQA, ensuring you get the best possible fidelity from your digital music library.
The HDMI 2.1 module is an optional upgrade for the TDAI-3400. You should check the specific configuration of the unit you are looking at to confirm if the module has been installed.
The TDAI-3400 delivers 200 watts per channel into 8-ohm speakers and 400 watts per channel into 4-ohm speakers. This robust Class D amplification is sufficient to drive most high-end bookshelf or floor-standing speakers with ease.
