    The order arrived within the prescribed time by the seller. The complete set corresponds to the description. The DAC was connected to the TV via TOSLINK to the old audio system from Panasonic, works well. Also, the headphones were connected to the appropriate connector on the front panel, too, everything works well (the only note that this device is not very good at working through the monitor headphones,,, since the quality does not reach their playback level, but this prefix for such purposes and is not intended). So if anyone needs not an expensive device for an old audio system-I recommend.

  5. R***r

  6. k***i

    Very cool used by kdac for another amplifier I have to control the level of bass and treble, very suitable for me only it is very small size

    The order came in 14 days to Kiev. Packed all very well.
    Thank you seller.
    Surprisingly, the DAC was very compact. I’m testing now.
    Bought for use on PC: games, music, movies.
    The sound pleased the owl with clarity and softness, quite warm and voluminous gives out sound.
    For such a price-definitely to buy.
    Postulat: no matter what the marketing is, the built-in sound on the mother, this device gives another sound to the order.
    I liked the convenient function, when you turn off the headphones automatically the signal goes to active acoustics. Or, if the acoustics is connected through the sound on the motherboard, then when the DAC is turned off, windows automatically returns the signal to another audio device.

    Sounds great, I ‘d say better than a Kguss I bought before. The only thing I didn’t like was the size, the box is small and light, the weight of the wires moves it. The knobs the little ones difficult to manipulate.


  9. V***r

    Nice goods, delivery on grade. Sound then listen long new rating is.


  10. A***f

    Всё отлично работает, брал на замену
    встроенной звуковой карте, гораздо лучше звучит. Наушники тоже отлично звучат (ССА С12).


  11. K***k

    Very good sound, good quality of materials, recommend!


  12. K***G

    다른 분이 이야기 하시던
    앰프 화노는 고가의 이어폰 사용시 들립니다.
    헤드폰에서는 들리지 않는걸 보면
    임피던스가 낮은 이어폰은 사용 하지 않는것이 좋을거 같네요. 다른건 적당 합니다. 가격 그대로 정직한 성능.


  13. l***r

    Receive the goods after about 20 days, quality good, sound is greatly improved compared with Ko use DAC. 5 stars. Good job.


  14. f***a

  16. E***a

    Very good arrived early, the sound is excellent loved.


  17. J***m

    Great product! Shipping to Australia was really quick!


  18. D***n

    For the price that is offered the goods is very good.
    The sound is good, the gain is good.
    Who needs a budget sound card with a headphone amplifier, then it will suit quite.


  19. I***n

    Excellent packaging, good equipment. Headphones that in the photo sang at times better. When connected via a USB hub or USB on the front panel, there are clicks when working. If you connect directly to the motherboard, everything is fine.


  20. I***n

    It came in 6 days from the warehouse of Moscow. Everything works fine, the gain is enough with a large margin. The only thing happened was the Kazus, connected two cables to the PC by yusb, one power supply, and the other for sound transmission. I turned on the computer first, I downloaded it, then I turn on the volume of the amplifier, and my computer goes to protection. I do not know what the case was, then I already turned on the computer with the included preamplifier and everything worked fine. The thing is cool, for not a lot of money, cost on sale at a discount and coupon for 2174 rubles.


  21. S***s

    For such money, a thing. He listened through the Beringer, his ears clenched through the tsapik, and heard the low ones. Frequency adjustment is good. Not separate volume (ears and speakers) is bad.


  22. J***B

    excellent mini dac for PC and headphones. works easily with the PC and there was no software required to download.


  23. O***v

    I took for 1900, for this money is normal)) the sound strengthens)
