1, Tianyi at2300 received four double eight-inch floor boxes, one with a center speaker and two rear surround boxes. I feel lack of motivation, heavy appearance and immature design. Tianlong 2700 power amplifier has sufficient power, 7-channel power is not discounted, full thrust, beautiful appearance and mature design.

2. Power amplifier brand list 10: Tianyi (English: tone) Tianyi, a high-tech enterprise in Guangdong Province, a well-known brand in the field of AV amplifier in domestic audio equipment industry, and one of the top ten AV amplifier brands, Guangzhou Tianyi Electronics Co., Ltd.

3. However, the sound quality of Tianlong 0HiFi power amplifier is not as good as that of Tianyi 0 A power amplifier, which is beyond doubt-because Class A power amplifier is the best, which is one grade higher than ordinary HiFi power amplifier.

4. If Euro 95 Watt is driven by seven channels and connected with seven speakers, the actual power is only 70 Watts (the power consumption of the whole machine is 500 Watts), and the actual output power of this power amplifier is only tens of Watts, which is poor in cost performance! It is suggested that Taobao buy Tianyi ad-3d, 8-ohm output 150 watt Class A power, which is twice as powerful and sound quality as Tianlong Power Amplifier! The price is also more than 5 thousand.

5. Tianlong S650 is a home professional Bluetooth high-power fever 2-channel amplifier, which is suitable for home theater sound system. Tianyi 86D is a multi-functional HIFI family super Class A Bluetooth high-power amplifier, which is suitable for high-fidelity music playback system. As for which is good, it depends on your main purpose.
