One owner piece. Excellent condition, sounds fabulous. Rarely seen on the used market. |
In its simplest form, the TDAI-2200 is a digital integrated amplifier with 200-watts x 2 into an 8-ohm speaker load and 375-watts into a 4-ohm load. Before you wince about the word digital in the same sentence as amplifier you should know that the TDAI-2200 is a true digital amplifier. In fact, TDA in the model number stands for True Digital Amplifier (the ‘I’ stands for Integrated).
Simply stated, most digital amplifier designs are actually analog-digital hybrids. In the hybrid scheme, the PCM (pulse code modulation) incoming PCM signal of a CD player is converted to an analog signal then converted once again to a PWM (pulse width modulation) digital signal in the output stage of the amplifier. This design is widely used because of its lower cost; however, it can result in increased harmonic distortion particularly at very high frequencies, as high as 80-100kHz. Some may argue that the human ear cannot hear frequencies higher than 15kHz to 20kHz so distortion at 80kHz is no big deal. I would make the point that 80kHz is the 3rd harmonic of 10kHz and that the accurate reproduction of harmonic frequencies are critical to true high fidelity reproduction.
The TDA design converts the PCM signal directly to a PWM signal (digital-to-digital), eliminating the digital-to-analog-to-digital conversion process and resulting in an unbroken digital signal path. It’s dubbed Equibit, and is the foundation of the Lyngdorf design.
I won’t repeat all of the accolades , but suffice to say that if you’re a critical listener interested in a refined audio listening experience, you must hear the Lyngdorf system before you make an investment in high-end audio components.
