Product Description:

TPA6120 is a current feedback amplifier with excellent performance, its distortion is far more than many op amps that only handle small signals. What's more frightening is its frequency response, which can surpass the video, directly to the radio frequency, from 10Hz to 100MHz! There is also a rise rate of as high as 1300V per second, which is a breakthrough chip design.

LME49720AN, compared with various indicators, LME49720AN is better than OPA2134, especially 100KHz triangle wave and square wave. The three-frequency LME49720AN has good balance, good dynamics, high low-frequency intensity and volume, wide sound field and smooth high-frequency. The timbre is very naive, the sound is very light at the beginning, there is no modification or coloring, especially the texture and sense of space are very good.

ES9018K2M decodes less sound, the sound is more real, the index is higher, and the sound is more plastic. You can create different tones according to your needs.

The amplifier/preamplifier automatically switches. When no headphones are connected to the DAC-K3 PRO, the RCA output is in front mode, and the amplified signal is output from the RCA interface. When the earphone is connected to any interface, the DAC-K3 PRO will automatically switch to earphone mode, and the signal will only be output from the earphone jack.

DAC-K3 PRO is not only a professional headphone amplifier, it is also a pre-amplifier, as a pre-amplifier can also play the same excellent performance, widely used in power amplifiers or active speakers!
