Clear's 9 advantages

1. Pure tone system, the main control power consumption is extremely low, the code is more pure. Have lower jitter and latency than Android system.

2. 5 x Opa1612 + 2 Opal622 Ti flagship OPamps, providing approximately one in 100,000 ultra-low THD.

3. 14 x TQC 107 polymer capacitors provide independent power for each OP, ESR as low as 55 mΩ, only 10% of ordinary tantalum capacitors, providing pure energy.

4. The two ES9038Q decode the left and right channels independently, providing maximum separation.

5. CS8421 Independent clock reorganization, the Jitter is reduced by one order to 50ps.

6. Output reaches 7V VPP single-ended, 5 times that of conventional products, easy to drive high-resistance large headphones.

7. Tps7a30 and Tps7a47 ultra-low noise (16μV) instrument-grade LDO power the analog.

8. 27mHz + 50mHz audio dedicated TCXO crystal oscillator, providing a stable and high-precision clock for the digital end.

9. Aluminum CNC body + tempered glass 4 screen ID design, an irresistible texture.

 

What are the weaknesses of HiFi?

It’s on the analog side. The DAC chip has been upgraded from the early WM8740 to AK4499 after ten iterations, and the analog end has hardly developed in decades. Most manufacturers choose to upgrade the DAC with more selling points, and CLEAR has been repeatedly studied at the simulation end and built with fine materials to achieve an amazing HIFI-level hearing feast.

 

16μV ultra-low noise power supply

In order to achieve an accurate balance, the feedback/load resistance adopts the Japanese KOA thousandth precision patch resistor, which is not only highly accurate, temperature drift but also only 10% of the ordinary carbon film. The cleanliness of the analog power supply directly affects performance. To solve this problem, Xuelin used TI's instrument level power supply chips TPS7A30 and TPS7A49 in CLEAR, which has ultra-high power supply rejection ratio (RSRR) performance and output noise as low as 16μV/RMS. Not only does it help meet the broad input voltage and minimum noise requirements, but it also leaves the most room for transients.

 

6063A magnesium alloy body

The body is made of 6063A magnesium aluminum alloy, CNC integrated processing, surface frosted anodizing process. Classic and modern elements highly integrated exquisite appearance ID, more in line with the preferences of professional players. Thanks to Xuelin's 20 years of audio development experience, numerous tuning and testing of CLEAR, so that CLEAR still achieved 126dB at 7.1V output SNR and low distortion within 0.008%, laying a solid foundation for good sound quality.

 

POSCAP polymer capacitance matrix

Most of the power capacitors used in portable players is designed to be tens of micrometers, which limits the dynamics of the sound and the sense of scale of the sound, while also reducing cleanliness. CLEAR uses 14 pcs 100UF POSCAP capacitors to power the analog circuit. The POSCAP capacitor ESR is approximately 90% lower than ordinary tantalum capacitors, providing better frequency and transient response.

There's an organic quality to the Clear's playback I don't quite get from any of the recent Android DAPs I've tried. It delivers powerful, elevated levels of bass without sounding bloated. This gives the sound a real sense of gravitas with impressive note weight & drive. Clear boasts a warm tonality with enough lower midrange emphasis to make music sound satisfyingly bodied & full. Clear is hugely dynamic, with dynamic swings that really pop out and contribute massively to the player's palpable sense of groove.
