Luxury & Precision L4 Digital Audio Player.


In very good condition. A few light scratches on top around jack ports but hardly noticeable. This player does not disappoint and offers amazing sound through the D8000 headphones more so than my ex SP2000 offering a far more natural musical experience.

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

Description

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
