QA361 HiFi Lossless Pure Sound Music Player

QA361 HiFi Lossless Pure Sound Music Player

Spur with longterm accumulation, Just for the uncompromising sound quality

Where is the ceiling of the portable player?

In high-end desktop player, and high-end desktop player with better sound in the future.

The portable player we make is to be infinitely close to the desktop player.

QA360 has a title of a concentrated small desktop player and QA361 is more close to the desktop player.

Make efforts to achieve the extremely clean and penetrating sound base, the delicate and pure emotion restoration, the easy and elegant sound style

Make efforts to let the sound to be more comprehensive, more perfect, more pleasant, more touching base on QA360LE sound base, try to let the penetrating purification, the feeling of music and fluency to be ultimate, achieve the unique sound quality in the current selling audio players.

Finally, QA361 sound style is derived from QA360LE, the same easy and elegant, as well as nice, compare with QA360LE, it is more penetrating, more condensed and delicate, better treble and bass extension, more excellent feeling of music, more graceful and natural, soft and with the feeling of quality.

EIGHT SELLING POINTS

1. It is adopted by the single-chip computer single thread ultra real-time code, make sure the sound to be more purified, more details can be restored.

2. It rewrites the code full linear reading card, and isolates TF card power supply, the sound background is more black, more purified and natural.

3. 0.088ps double femtosecond crystal vibration provides the clock for the overall synchronization of the whole machine.

4. Two 470000uF super capacitors independently supply the power to the analog and digital.

5. 6 OPA1622 achieve four kinds of trust mode of ear amplifier: Standard, Large current, High voltage and Dual-high.

6. AK4495SEQ sound quality special edition + high voltage power supply, make sure high quality and the good feeling of music.

7. Enhanced capacitive load driving capability can drive the capacitive load larger than 2000pF.

8. The sound is extremely penetrating, delicate and has the very excellent feeling of music.

Power supply is the mother of sound

Very purified, Very steady, Very low internal resistance power supply design

Power supply is water while music is life, the pure water creates the wonderful life, the pure power supply reappears the moving sound.

QLS-HiFi always insists on the tuning concept of power supply is the mother of sound, because power supply is the head of bottleneck to affect the sound.

All power supply is independent, Not influence mutually, With the characteristics of ultra high speed and ultra low noise, As well as ultra output internal resistance

Clean, penetrating and delicate are the largest characteristics of QA361 sound, and it is closely related with the investment of power supply.

Super Power Supply, Supported by Double Super Capacitors

Respectively supply the power to the analog circuit and digital circuit

A good clock can be described by a word "Steady"

A good clock basically has a full, firm and condensed bass, it can be described by a word "Steady".

Steady shows it should be clean enough, treble response should be guaranteed by the enough good power supply.

The clock is the soul of sound

QA361 is adopted by an overall unified high precision femtosecond clock

Refer to dCS monolithic clock synchronous supply design, the whole situation is derived from the femtosecond clock, it is equal to the clock synchronous function is used in the audio and DAC.

QA361 Adapts To The Crowd

1. You have the high-end player, and want to experience the pure tone mode and the extremely penetrating sound again, QA361 is worth having at the same time.

2. If you have the near ultimate pursuit for the sound, and you prefer to compromise the other aspect, QA361 is developed for you.

3. If you pursue the penetrating and delicate, and the good feeling of music, as well as the smooth and natural sound, QA361 is very suitable to you.

4. If you play the binding for the sound quality, do not miss QA361, it will alleviate the binding for you.

5. If your payer in hand can not drive your headphone / headset, or can not drive well, you can try it.

6. If you love to listen the classical background music while reading, QA361 can bring you the natural and smooth sound to you.

7. If you like the sound balanced advanced desktop system, and want to experience the similar as the easy and elegant sound from the carry-on device.

8. If you have a busy work and big pressure, and want to listen the good music quietly, seek for a music can touch your soul.

9. If you are a worker in charge of music, and need a player for listening the extremely penetrating, extremely pure restoration music.

10. If you have a lot of headphones / headsets, and need a player can drive most of earphones.

11. If you are an audio researcher, QA361 excellent and pure sound can help your work.

In a word, The friends who have a certain pursuit for the sound quality, and can accept the pure sound player, QA361 is the best choice for you.
