In Russia, they delivered fairly fast-3 days. Packaging Outer is a package, but inside all in thick factory packaging, so and lamps, and everything else is fine.
Quality, alas, not supper-Puper, but, buying a device for such a price, it is necessary to understand, what you’re counting on. The amplifier tube itself is not bad, but everything else is still on the chips-and the DAC, and Bluetooth, and the chips also cost good money. Subjective I liked the external sound card from creative, than the sound of this device, but Sound Blaster in itself contains some other mathematics, the interface for setting, and then even the driver is not put, of course no DTS and эквалайзера, sends the signal from the input to the output.
In general, a disputed acquisition is not so expensive that it would play and throw out, but on the other hand, maybe it will serve…

Это самая лучшая покупка на али ))))) Наушники Audio-Technica ATH-M50X зазвучали по новому, появились басы, верха, громкость! Также подключил к усилителю простые колонки и они также заиграли ))) Я не аудио эксперт и возможно мне медведь на ухо наступил, я не слышу искажения АЧХ, про тёплый ламповый звук только читал, я обычный пользователь, который очень доволен остался этой чудо-коробочкой ) Одно отмечу, что звук через Bluetooth хуже, чем через USB и RCA.

Muy contento con este preamplificador, mejora bastante la señal que daba mi tocadiscos. Tenía dudas con el bluetooth pero va muy bien, aunque solo lo he probado a poca distancia del dispositivo. Al vincular el bluetooth hace un pequeño sonido, pero la reproducción es buena. Muy recomendable

Very good and high quality. The sound is pure without any noticable noice or distortion. I tried different tubes but ended with russian 6Z1P, which has warm colorful tone with sweet mids and strong bass. You can turn on/off the equalizer and lights (blue/orange/off) for tubes. I like it very much. See pictures – used with tube amp.

звук хороший, тембр блок работает отлично, качество звука стало лучше. Как внешняя звуковая карта работает. коробка пришла немного помятая, но это не беда. А вот что расстроило, так это то, что ручку баса немного деформировало с угла, так как в коробке не предусмотрен поролон над ручками. в остальном все ок. подходящие русские лампы 6ж1п
I***P –
Особого изменения звучания не заметил. но как минимум смотреть на подсвечивающиеся лампы весьма залипательно) Кстати без ламп не работает, так что вроде бы не бутафория) размером маленький совсем, думал он побольше) В целом доволен – рекомендую!))

To St. Petersburg 15 days. Preamp chose purely from the reviews of compatriots, many thanks for the detailed reviews. Drove him for four days. I liked the sound very much, right from the box without much warming up, it sounded very rich and clean and very detailed. He noticed that many sounds before were not so clear, and those who were embezzled became more delicate detail as if broken into sectors. I use a bundle of Bluetooth CD-preamps-receiver (through decoders 7.1) -The sound picture covers on all sides even now denser. I plan to experiment with Russian lamps. Of course, I did not expect a strong increase, but 15-20 percent of the sound changed this obviously. Checked on USB from the laptop hi rez files-impressive. See the overview how to get around through ASIO or WASAPI push the sound equation in Windows 10. Bluetooth also works better, the lamps pull out its meager sound. I’m happy, it’s worth it, in its price category of course.

Получил довольно быстро. Все входы-выходы работают, качество сборки отличное. Лампы в гнезда становятся туго, что хорошо. Подойдет не для всех жанров, голос звучит классно, верхи и низы не супер, но и не особо плохо. Есть поле для экспериментов с лампами.

really good preamp/ dac, the sound is really good for the price, it makes my class D less clinical ! solid build and the switches and nobs feels like quality. off course i changed the tubes for Brimars, the usb for a quality one and the power supply for less noisy smps…

Equipment Works and sound good, and even better… Zobaczę are we wygrzaniu lamp will still change, it can also pomyślę about dokupieniu reputed more lamps. Presents well at my Luxmanie R1030. To which sterility, added bit softness and body, especially in bassach. Mount I impression also slightly better, przejrzyściej, hard tell whether zasluga DACA or lamp but is przyjemniej. Bluetooth not przerywa, RCA blends well Melodiki amplitunerem for cables. Not tried it connect to laptop yet.
