Hi, friends!
How are you?
Sinbosenaudio ended the holiday today! We are back to work again!
I received surprise feedback from customers as soon as I came back! It is a customer from Latvia, and the feedback power amplifier is K4-600 digital power amplifier. I am so happy to receive this feedback. So can't wait to share it with you all. Hahahaha. Let's take a look!



This is what the Latvian customer said:

Отличный усилитель !!! Три дня жёстких испытаний прошли успешно. Может только постоянный шум кулеров мог быть меньше и включаться только при высокой температуре. Конечно надёжность под вопросом. Звук превосходный. Низкий уровень собственных шумов. Продавец выше всяких похвал. 

Great amplifier !!! Three days of rigorous testing were successful. Maybe only the constant noise of the coolers could be less and turn on only at high temperatures. Of course, the reliability is in question. The sound is superb. Low level of intrinsic noise. The seller is beyond praise.

Пользуюсь каждый день, уже две недели. Вентиляция на нагретом усилителе , по мне так могла бы быть тише. На пиках НЧ срабатывает защита.На короткий период проподает сигнал в каналах субов. Звук хороший.За такие деньги , очень даже адекватный усилитель.

I use it every day, for two weeks already. Ventilation on a heated amplifier, for me it could be quieter. The protection is triggered at the low frequency peaks, and for a short period it transmits a signal in the sub channels. The sound is good. For the money, a very adequate amplifier.



This is really a great feedback. Thank customers for their super support. Since the K4 series, many customers have inquired about K4-450 and K4-600 digital power amplifiers. We are also collecting feedback from the K4 series to show to Sinbosen friends.
