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.
