What does it cost to get great sound quality?Now, with the continuous progress of technology and the intensification of market competition, the thousand-yuan power amplifier has also shown remarkable strength. Among them, the AD-86D power amplifier of Tianyi Audio has become a hot seller in the thousand-yuan power amplifier market with its excellent sound quality and high cost performance.
The AD-86D is designed with attention to detail and quality. It is made of high-quality aluminum alloy, treated with anodizing technology, and the fine polishing makes the box smooth and delicate, which not only has excellent wear resistance, but also effectively resists external interference.
At the same time, the design of the giant comb-shaped radiator ensures stable heat dissipation under high-power working conditions, and prolongs the service life of the equipment.
The terminal blocks are electroplated with 24K gold plating, which is corrosion-resistant and improves the stability of signal transmission. In addition, the design of the bottom honeycomb shockproof feet further reduces the vibration interference during operation and ensures the purity of the sound quality.
When you open the chassis of the AD-86D, you can see that it adopts a five-box sealed structure, which strictly isolates the power supply, input, energy storage, and left and right channels without interfering with each other. This design effectively reduces the noise floor and improves the purity of the sound quality.
In terms of component configuration, the AD-86D does not hesitate to use audiophile-grade components, such as OPA1678 op amp, NJW1194 volume chip, 400VA giant ring cow and eight Toshiba famous tube TTC-5200 TTA1943, etc., which provide a strong guarantee for excellent sound quality. At the same time, the addition of six high-quality filter capacitors with a total capacity of up to 57,400 microfarads makes the power amplifier more calm and unhurried in the large-scale dynamic performance.
The AD-86D is even more remarkable in terms of sound quality. It adopts the super class A circuit design, the perfect combination of the pre-stage high-fidelity op amp and the post-stage differential amplification circuit and the mirror constant current source load, so that the loss of the best signal in the transmission process is minimized.
After several levels of current and voltage expansion and amplification, as well as the amplification of dual Darlington power amplifier circuits, the AD-86D presents ultra-low distortion sound quality characteristics. Whether it is the dynamic melody of pop, the melodious voice of classical instruments, the delicate emotion of the vocals or the dynamic scene, it can be perfectly interpreted. When listening to the classic tracks, you can feel the notes in your ears, and every detail is clearly recognizable, making people feel as if they are in the first hall.
As a thousand-yuan power amplifier, AD-86D not only shows unimaginable strength in terms of exterior design, internal configuration and sound quality performance, so that enthusiasts can enjoy a high-quality sound experience within a limited budget. If you're still hesitating about the high cost of the amplifier**, then try the AD-86D, which may give you an unexpected sound experience.
