White Advanced Version DC11 Music HiFi Decoder 4PCS PCM1794 Bluetooth5.3 Ultra-CD Dynamic Dual Transformer

White Advanced Version DC11 Music HiFi Decoder 4PCS PCM1794 Bluetooth5.3 Ultra-CD Dynamic Dual Transformer

Difference:
- Advanced version: adopting 2pcs OPA627 single operational amplifier + 8pcs V5i dual operational amplifier
- Standard version: adopting 2pcs NE5534 + 8pcs NE5532
- The advanced version has a comprehensive improvement in sound quality compared to the standard version, and it is not necessarily a case of one frequency band being advanced and one frequency band being standard. The advanced version has better overall sound extension. The music has clearer overtones, better overall transparency, and significantly improved penetration. The feeling of unboxing is very natural, and the on-site experience is more realistic. The sound ends cleanly and clearly, and there is a noticeable feeling of good elasticity when the drumming ends. The sound is thick, full of charm, and full and round.

Feature:
- Size parameters: 430 x 80mm x 260mm
- Double ring transformer power supply, pure Class A power supply system, multiple independent power outputs.
- Unique HIFI level left and right channel separation chip, not a simple 4-parallel system.
- 24K gold-plated circuit board, further reducing onboard impedance.
- High voltage operational amplifiers with positive and negative 18V power supply can unleash the potential of the machine.
- All aluminum chassis, with a net weight of 5.3Kg for the entire machine.
- Simple design, easy operation of the whole machine, with power-off memory function.
- This is a pure decoder without player function. USB does not support USB playback. USB is used to connect digital players with OTG output function such as computers, phones, tablets, and for Daphile hosts.
- Note: This decoder does not have a volume adjustment function. Cannot be directly connected to a pure rear stage amplifier, it should be used together with the preamplifier.
- It's not just four PCM1794 chips connected in parallel, but with the addition of a HIFI level left and right channel separation chip, the sound field is wider and the separation degree is higher. Plus linear pure Class A power supply. Powered by a positive and negative 18V operational amplifier, with 10 operational amplifiers, the output level can reach up to 3.6Vmr, which has greater output dynamics than the 3.0Vmr of a professional CD player. The sound is transparent and beautiful. Low frequency diving has elasticity.

Note:
- Although the USB Italy interface can support up to a maximum DSD512, the PCM1794 decoding chip can only decode up to 24B192k and does not support DSD decoding. Therefore, the final machine can only support a maximum sampling rate of 24B192K, and if DSD needs to be played. To play, it is necessary to set the software decoding mode (PCM output mode) on the computer or mobile phone.
