GUSTARD A18 AK4499 DAC Native Balanced DAC Decoder DSD512 Silver Version For Audiophile Music Fans

Features:
- New A18 adopts XU216, with optical input.
- Native balanced decoder: AK4499EQ, CPLD digital processing, 4-channal 8-way IV, LME49860*4. Active LPF LME49860*2, For XMOS DSD512, PCM768K. AS318-B femtosecond crystal oscillator. For LDAC HD audio transmission. Multiple independent power supplies, abundant energy, TPS7A47, TPS7A33. IIS-H input. Fully balanced, complete four-way output without any conversion. Digital filtering, 6 types of PCM, 2 types of DSD. 0dB to -90dB full-function remote control.
- Leading technology for collecting critical time information, bringing you into the acoustic performance scene. Before using the technology, common digital audio filters would compromise time resolution, and there would be buzzing before and after transients. After using it, compared with 24/192 recording, it reduced the number of vibrations before and after by more than 10 times.
- Make large high-resolution files easy to manage and compatible with any service or playing device. On ordinary players, it plays better than CDs. Using the decoder, it can present complete and rich studio sound quality.
- Products with full decoder can fully expand files to provide the best sound quality. Playing at this level, you will hear the original sound created by artists in recording studios, with accurate files and platform-specific DAC compensation and management.
- AK4499EQ: Flagship decoder chip, completely independent power supply, independent grounding, to obtain excellent performance.
- CPLD programmable logic chip, professional customized HIFI system. Self-constructed digital integrated circuits with logic functions, clock management, 2ND PLL digital shaping, DOP demodulation, PCM/DSD depop switch and other exclusive technologies have laid a solid foundation for excellent sound quality.
- Four LME49860 dual op amps form an independent four-way IV, which fully meets the requirements of AK4499 high current.
- Independent voltage stabilization, multiple groups of filtering, left and right separation, no mutual interference.
- Premium linear power supply: Built-in high-quality audio dedicated linear power supply.
- Active LPF circuit uses 2pcs LME49860 dual op amps.
- Adopts 0.1% high precision, low temperature drift resistors.
