Streaming amplifier with optional MM & HDMI modules

Tailor your setup and sound

Through the web interface you can perform all setup and operations from the menu system, which allows you to tailor your setup and sound, and the digital crossover allows 3 individual output settings. With our proprietary RoomPerfect™ room-correction software to eliminate the negative influence of the listening room, the TDAI-3400 delivers a perfect sound without the need for extensive room treatment.

Connect audio and video sources

A variety of inputs and outputs provide plenty of options to connect your audio and video sources: Seven digital inputs including optical, coax, AES/EBU, USB-B, USB-A, two RCA analog inputs for analog music sources, one optional analog module for more analog inputs including XLR and phono MM, and one optional HDMI 2.1 module with two inputs and one ARC / eARC output.

Built-in media player

The TDAI-3400 accepts all media interfaces and features a built-in media player with the highest playback quality. Through your local network or via the USB connectors, you can access your entire library of music through the DLNA/UPnP enabled player. This media player also allows music streaming using Roon Ready, Spotify Connect, and AirPlay 2 as well as internet radio. The TDAI-3400 also supports TIDAL Connect which allows lossless audio quality with the TIDAL app as the controller, and it includes the MQA Core Decoder, which unfolds the MQA file once to deliver better than CD-quality. MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording.
