I have been testing it for a few days and it is a pleasant surprise. Here are some of my feelings: 1. The overall appearance is quite solid, and the panel and remote control buttons feel average! 2. The operation is simple and user-friendly, without too much tediousness! 3. The living room party 5.1, after installation, the test microphone automatically optimizes each channel. It is simple and clear, and each channel can be debugged separately, which is very good! After setting it up, I tested a few movies I had watched before and was surprised. The sound field is surrounded, the channel separation is clear, the sound is full and strong, and the amplifier noise floor is well controlled, which is beyond my expectation! 4. The built-in karaoke system is generally OK! It supports Bluetooth, USB flash drive, and memory card to play songs. It is very playable, and the EQ inside can be adjusted independently without conflict. 

After using it for a month, I am very satisfied with the TW AT-2000 AVR amplifier. It is of high quality, easy to connect, and it is so good for watching movies that I don't have to go to the theater anymore!
