Luxury&Precision L4 32GB CS43198DAC Portable HiFi Walkman Lossless Music Player


Pure and quiet

  • No noise analog sound, L4 HIFI music player

Dual CIRRUS new flagship CS43198DAC professional HIFI version

  • QFN package, enhanced large pad, more stable sound, better thermal and better performance version

Designed for earbuds

  • Output adapts to various earbuds, easy to drive
  • Small and portable, the good companion of earbud.

Challenge test instrument range

  • -130db signal-to-noise ratio, THD+N 0.00056% @ PO 32ohm load, create new height!

Especially optimized for low impedance high sensitivity earphones

  • ANDROMEDA earphones all cannot hear low noise, total harmonic distortion is 0.00078% at 16 ohm load

Non-public version which is designed for good sound

  • Complete DAC -> buffer -> amplifier signal chain architecture, achieve high performance while maintaining a good sense of hearing.

High-end configuration

  • Silver-tantalum capacitor is same with L6 series, a PSRR of up to 100 dB LDO, and a high conversion rate bipolar op amp with noise below 1.2 nV/√ Hz.

Native support 32/384

  • A higher sampling rate means more detail and supports a variety of HD audio formats, which are with good sound and convenience.
  • Six professional filters, adjustable phase, high and low gain, good news for patients with difficult choices of earphones.

FPGA aid high precision clock

  • Lower jitter, better S/PDIF output quality, good partner
