Description.
Xduoo X20 is an audiophile player from one of the leaders in the portable Hi-Fi market segment. This time, craftsmen from the Celestial Empire did not submit to the discerning public for consideration the basic device created to gain leadership positions in the mid-budget price range.
Xduoo X20 housing is made of aluminum aircraft type. Cam display offers a whole comfortable for everyday use diagonal and resolution. A set of connection interfaces represented a 2.5-mm balanced, and 3.5-mm headphone output port USB type-C, as well as combined with a digital coaxial line connector. administration scheme is shown the power key, volume control, play tracks, and navigate through menus, placed on the side faces of the housing. Further, it is worth noting some of the key technical aspects devaysa, such as the connection option to the PC as the USB-DAC and module Bluetooth 4.0 bidirectional supporting aptX codec mode and Bluetooth-DAC, which is also able to synchronize your player with popular software service HIBY Link. With regard to the internal battery, this has a capacity of 2400 mAh, which provides up to 7 hours of continuous operation at the audio listening with headphones wired on the balanced output.
The main advantage Xduoo X20 is its internal equipment, among which the best estimates of the true merits audiophile 32-bit DAC ESS Sabre 9018Q2M with a sampling frequency of 384 kHz and 256 support the native DSD previously encountered in solutions with a significantly higher cost. It is further noted amplifying path, wherein the key link served opamp TI OPA1612, providing output at 210 mW (32 ohms) for asymmetric connections and 300 mW (32 ohms) to a balanced line. It is important to mention that there are two nizkofaznyh crystal oscillators (crystal), operating at frequencies of 44.1 and 48 kHz, which are designed to minimize jitter and CED. In terms of the specifics of audio playback Player demonstrates the expected strong performance in respect of natural sound flow along with the proper construction of the imaginary scenes and a clear separation of the instruments. Furthermore, sound characteristic X20 and delicate manner wagering frequency ranges due to their elaboration and emotional component and closer to authentic tonal color.
In a black black box, the new owner will find a black player with a protective film attached to the protective film;), USB and coaxial cables, an additional two screen protectors, silicone “paws”, 2 gags for mini jack outputs (not always), a set of documentation and a cover from a young Chinese dermanthin (in new deliveries).
