Designed, developed, and manufactured in Denmark, the TDAI-2170 is a masterpiece of substance and style. The amplifier’s chassis—a salute to modern industrial design—is built like a tank and dressed in the signature black finish that fans of Lyngdorf Audio love. The design is complemented with black glass and aluminum in a sleek profile that complements any décor. In addition to being fully digital and having flexible upgrade modules and RoomPerfect™ room correction technology, the TDAI-2170 provides the formula for a sound experience that has left critics and listeners astounded.

True digital amplification

The TDAI-2170 is 100% digital, without sound-deteriorating digital-to-analog conversions. The digital signal drives the speakers directly, with no translation and no middleman. This unique and technically demanding solution offers noiseless and crystal clear replay at all sound levels. It will deliver the most enjoyable and uncolored sound you have ever experienced.

Benefits for all speaker systems

Whether used with full range, satellite, in-wall, or on-wall speakers, the TDAI-2170 is the perfect choice for any brand or model on the market. Because of its unique technologies, the long-contested challenge of speaker placement no longer compromises performance. On the contrary. Simply place your speakers up against the wall to get the least amount of damaging reflections. From there, RoomPerfect™ will adapt the speaker to the room and remove any unwanted bass boom.
