Crosbon CR-939 Hifi Audio Power Processor CR939 Audiophile Power Conditioner (with Black Panel)

Crosbon CR-939 Hifi Audio Power Processor CR939 Audiophile Power Conditioner (with Black Panel)

Attention:
* Many audiophile enthusiasts have specific requirements for cables; therefore, this unit does not include external cables.

Description:
The CR-939 is Crosbon's flagship HiFi audiophile-grade audio power processor. It was originally manufactured following the design concepts and raw material sourcing standards of foreign brands. After delivery and with the client's approval, the product was redefined as part of the company's own brand lineup. This indicates that the product may have already established a strong reputation in the international market, and the company has decided to promote it as its flagship product.

The CR-939 is a high-end HiFi power processor capable of providing extremely low-distortion sine-wave current to the front-end components of an audio system. It also delivers sufficient high current to power two monophonic power amplifiers, achieving balanced performance.

The CR-939 performs well and has an exquisite appearance. It uses an iron chassis instead of an aluminum alloy chassis. Iron is relatively economical and also provides good electromagnetic shielding, which helps reduce interference and maintain sound quality.

In HiFi audio systems, the choice and design of filters have a significant impact on sound quality. Using a filter with large inductors combined with large capacitors can provide the following benefits:
1. Better Ripple Suppression: Large inductors can suppress high-frequency noise, while large capacitors smooth the voltage waveform and reduce output voltage ripple. This combination provides a more stable and clean power supply, which translates to improved sound quality for audio equipment.
2. Noise Reduction: In audio systems, power supply noise can couple into the audio signal, affecting listening experience. Large inductors and capacitors help minimize this noise transfer, ensuring a purer audio signal.
3. Improved Dynamic Response: Large capacitors can supply instantaneous current to support rapidly changing audio signals, while large inductors store energy to meet peak current demands. This combination helps improve the system's dynamic response, making sound more natural and fluid.
4. Enhanced Sound Quality: Filters with large inductors and capacitors effectively remove noise and interference between the power line and the load, enhancing overall audio quality. Music details become richer, and the sound becomes more realistic.

Features:
* The 10mm thick pure aluminum panel offers two different brushed finish color options. This design not only enhances the product's durability and aesthetics but may also improve the perceived quality and attention to detail.
* Using a large inductor with an iron core (for Nippon Steel) and wound with single-crystal oxygen-free copper, combined with a capacitor array (for NCC) of 16pcs 16V 33,000µF (M) high-capacity capacitors, it creates one of the best designs currently for maintaining dynamic performance.
* The effectiveness of a filter mainly depends on its inductance and capacitance. The power supply's inductance and capacitance must be specifically matched to achieve optimal audio filtering performance. It is not sufficient for some DIY vendors to simply buy generic industrial filter boards online and install them as audio filters. Even using industrial filters to make a filter, then testing noise with a low-cost power noise tester priced at a few hundred yuan, does not reflect the actual performance of the power supply under real use.
* RC surge absorption relay
* Choices in audio power supply design indeed reflect different design and performance considerations. Power switches may introduce additional contact resistance and inductance, which can affect power stability and sound quality. However, the Crosbon CR-939 power processor uses a high-quality power switch—the large pure silver contact Jialing switch—which effectively minimizes these potential negative effects.
* High-quality silver-contact switches generally have excellent conductivity and wear resistance, which helps maintain good performance throughout the switch's lifespan. If such a switch is well-designed, it can indeed provide sound quality comparable to or better than traditional switches, while minimizing any potential issues caused by poor contact.
* Exquisite craftsmanship. All materials used are of very high quality.
