The TDAI-2170 has three notable Lyngdorf design technologies: digital amplification, Room Perfect signal correction, and Intersample Clipping Correction (ICC). Digital amplification, as applied here, is not a loosely worded marketing gimmick, but real science and a newer way to amplify a digital audio signal. Some may criticize that statement, as most technology we see today has been around for a while but was not commercialized due to some impractical hurdle (such as cost) or a missing technological piece of the puzzle. And I am sure that is the case here. So, while the concept may not be new, there are not any digital amplifiers that I am aware of for consumer high-end audio applications that utilize the same technology as the TDAI-2170.

One finds nothing really to fault, and the sound gives the combined impression of delicacy and solidity that is characteristic of real music. The impression of reality is enhanced by the extremely silent background. Music emerges without any apparent electronic artifice.

I firmly believe the vast majority of individuals with white earbuds attached to their external auditory canals, can very much indeed tell the difference between higher and lower fidelity sound, they’ve just never had the opportunity! Enter Lyngdorf Audio’s new, fully digital integrated stereo amplifier, the TDAI 2170. Priced as a quality midlevel component, Lyngdorf Audio aims directly at the “iPod Generation” with a clean, adaptable user interface and uncompromising technology packaged in an elegant, familiar design.
