TDAI-3400

Why it is renowned

The British magazine The Ear reviewed the TDAI-3400 in 2020, with the optional analogue input board and Lyngdorf's CD-2 player; the reviewer was impressed by its sound from disc and from the built-in streamer, and by how finely RoomPerfect lets an owner shape the sound to a room.¹ It is Lyngdorf's most powerful amplifier, giving 200 watts a channel into 8 ohms and 400 into 4.²

The story

Lyngdorf introduced the TDAI-3400 in 2017, an amplifier with a DSP, voicing filters, a streaming player, modular options and RoomPerfect calibration.³ Its amplification is digital from end to end: the digital signal drives the loudspeakers directly, with no digital-to-analogue conversion in between.²

RoomPerfect, Lyngdorf's own room correction, measures the listening room with the supplied microphone at several positions and then corrects for the room.²¹ Optional modules add an analogue board with balanced XLR and moving-magnet phono inputs, and an HDMI 2.1 board with eARC.² The player takes Roon, Spotify Connect, TIDAL Connect, Qobuz Connect and AirPlay 2, and a digital crossover allows three output settings for speakers and subwoofers.²
