D300 TPA3255 Dual Channel HiFi Power Amplifier 300Wx2 High Power Bluetooth5.4 Decoding LDAC without Power Adapter

Description:
- The internal circuit has undergone rigorous design, using PCB with gold plating technology. The power amplifier circuit adopts advanced digital power amplifier chip TPA3255, with a power of up to 300W/4ohms and very low distortion, comparable to traditional Class A power amplifiers. By adding various advanced components, the overall effect has reached the ceiling of similar amplifiers.

- The operational amplifier used is the advanced operational amplifier JRC5532, which has delicate sound, balanced and durable. The potentiometer used is ALPS27 type potentiometer, and the filtering capacitors are two advanced audio capacitors for ELNARA series with a total capacity of up to 4400uf, effectively reducing power ripple. The LPF circuit of the power amplifier uses high-power inductors to ensure sufficient current and not compress dynamics. It is also equipped with advanced capacitors for red WIMA, which make the high-frequency sound pleasant to the ear, seamless, and full of overtones, eliminating the shortcomings of dry, cold, and hard digital power amplifiers. The Bluetooth part uses QCC3084 Bluetooth chip, which supports LDAC transmission rate of up to 96K/24bit and can achieve lossless transmission. Combined with advanced decoding chip PCM5102a, the Bluetooth part can achieve the effect of external advanced audio source, making it more convenient to use. In the current era of streaming media, this function is really very useful.

Sound Quality Evaluation:
- When the machine is turned on, it breaks away from the digital flavor of digital amplifiers. It is not dry at all, and the overall sound is very durable. The sound is clear and transparent, with a slight sweetness, as sweet as mountain spring water. Triple frequency balance, impartiality, clean and crisp low frequency, strong control, and clear hierarchy are major advantages of digital amplifiers. The sound field is spacious, the mid to high frequency is loose and natural, and the details are very good. The resolution of Bluetooth is also very good, without any loss.
