XiangSheng DA-06 AK4493/4495 DSD Asynchroner Xmos Decoder HiFi-Verstärker mit Fernbedienung

First, the reasons for choosing this machine:
1. The Xmos-Xu208 chip is used to receive the usb signal and the Spdif signal.
2. provide genuine custom exclusive xmos driver, there is absolutely no free public version of the drive will be a murmur.
3. AK4495 supports DSD128 and PCM384K, AK4493 supports DSD512 and PCM384K.
4. coaxial, BNC support DOP64 and PCM192K, fiber support DOP64 and PCM176.4K.
5. with remote control function, remote control channel switching, volume addition and subtraction, mute control.
6. there are balanced output, unbalanced output, amp output (optional) and so on.
7. Aluminum alloy wire drawing process panel, thin steel plate box, aluminum alloy wire drawing process cover, both beautiful and well shielded.
8. using R cattle power supply, the smallest magnetic leakage, the highest efficiency.
9. digital, analog power supply independent winding, independent rectification and filtering, power supply.
10. The standard operational amplifier is: OPA2134PA two pieces, OPA2604AU one piece.

Second, the use of precautions:
1. Master the correct sequence of power on and off to avoid impact sound. Power-on sequence: source--decoder--pre-stage--amplifier. The shutdown sequence is reversed.
2. Balanced output is connected to a power amplifier or amp with balanced input. Only unbalanced input amplifiers or amps can be connected with the RCA line, but only if the amplifier can pass the 4.5V high level signal without clipping.
3. The output of the machine is combined with the power amplifier. It can't directly push the pure final stage. The pure final stage should add the preamplifier.

Third, the performance characteristics:
◆ This machine has 4 digital signal input switching: BNC, coaxial, optical fiber, USB.
◆ This unit has a balanced output, a set of unbalanced RCA outputs, and a set of headphone outputs (optional).
◆The main magnifying board adopts double panel design and is made fine.
◆The resistor and capacitor of this machine are assembled with high-quality discrete heating components to ensure the sound quality: Siemens polypropylene capacitor, CBB ultra-small polypropylene metallized capacitor, ELNA capacitor, BC capacitor, etc., to ensure pure tone, high resolution, low sound. The sound field is wide and so on.
◆ xu208 uses 3 active crystal oscillators. It can effectively reduce the clock jitter of the USB port.
◆ The functions of this unit are controlled by MCU and memorize the channel status at the last shutdown.
