I received it today and it was much better than I expected. I found no negatives, only positives, always in relation to the price of €69. I connected it to Yamaha NS-IC600 ceiling speakers and the sound was quite good. Opening the lid was a surprise. It had a toroidal transformer and a rather careful construction with 2200x2=4400μf electrolytics on each channel. The heatsink was touching the chassis, screwed in with two thick screws, making the whole chassis, which is made of aluminum, a huge heatsink for heat dissipation. The transistor wiring suggests class AB, as experts will see on the heatsink from the photos I uploaded. Also, the relays for speaker protection show a more careful construction. Conclusion: for its money, it is a good amplifier. However, caution is needed as it comes in various versions and the interior is different. If it plays at low volumes, it is ideal; for higher volumes, we go to Fosi Audio, which is also of higher quality in construction

Guys, I got it with great difficulty because there were no reviews and there were no videos on YouTube, but as soon as it arrived, it was the best for its price. It is quite heavy for its size, all metal, and very good sound quality
