Интегральные усилители — Lyngdorf TDAI-3400

The TDAI-3400 is an integrated amplifier with a built-in DAC from Lyngdorf, built with a phono input alongside its digital and analogue connectivity. Lyngdorf is a Danish manufacturer with a distinctive reputation built specifically around its proprietary room-correction technology, applied across most of the brand's electronics range rather than treated as an optional add-on feature.

Position in line

It sits above the TDAI-1120 in Lyngdorf's integrated amplifier range. This positioning above the TDAI-1120 suggests the 3400 offers meaningfully more output and refinement, likely alongside a more developed implementation of the brand's signature room-correction processing that runs throughout its digital signal path.

Key specs that matter

One balanced and two single-ended inputs plus phono are provided. Rated output is 200 W into 8 ohms, doubling to 400 W into 4 ohms - a clean doubling suggesting a robust power supply capable of handling demanding loudspeaker loads without strain. Distortion is 0.05%. At 450 x 105 x 360 mm and 8.2 kg it is a compact chassis for its output rating, consistent with Lyngdorf's characteristic use of efficient class D amplification throughout its product range rather than a heavier conventional linear design.

Sound and use context

Expect a controlled, feature-rich presentation typical of Lyngdorf's room-correction-focused engineering approach, common across the brand's range - the room-correction processing here is not a minor bonus feature but rather central to how Lyngdorf believes a system should ultimately sound in a real domestic space rather than an anechoic test chamber.

Pairing

The built-in phono input covers a turntable directly alongside digital and analogue sources, a comprehensive connectivity set that should cover most typical two-channel systems without needing separate outboard units.

Alternatives

The TDAI-1120 sits below this model in Lyngdorf's integrated amplifier range, worth considering if this model's additional output and refinement exceed what a specific room and system require, particularly since Lyngdorf's signature room-correction technology is available across both tiers. Lyngdorf extensive dealer network across Europe and North America makes arranging a proper demonstration of the room-correction feature practical, and hearing the before-and-after difference in a real room is the most convincing way to understand what this technology actually contributes. A dealer conversation about the specific microphone and calibration process involved is worth having before assuming setup will be entirely automatic.
