Crosbon CR-939 Hifi Audio Power Processor CR939 Audiophile Power Conditioner (Alloy-colored 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.
