ALIENTEK D8 - Full Digital Amplifier
The FDA Class D amplifierSTA328DDX Alientek D8, complete controllable via remote control, integrates as standard an analog digital converter PCM5122.
Associated with an S / PDIF interface WM8805with a jitter of 50ps, an interfaceUSB XMOSon a separate card, this integrated amplifier opens the door to High Definition at a democratic price.
The quality of its components is high-level with a 12dB analog filter at the output of neat amplification featuring film capacitors, armored coils Miden 8A limiting the noise noise on the harmonics.
the analog input capacitors are audiophile quality Elna. The Alientek D8 will also be a desktop companion with headphone amplification MAX9722in 6.35mm jack capable of "driver" sedentary models with high impedance.
It has three digital inputs (USB, S / PDIF coaxial and Toslink optics).
Its bright, readable OLED display displays in real time the source used as well as the sampling rate of the audio file being played.
This all-in-one amplifier is also equipped with a digital equalizer with many functions (bass, treble, mute etc.) adjustable directly from the remote control.
hewill prove to be the ideal companion for any digital source.
Hisergonomics and compactness are notable advantages, plus its versatility.
