Despite the cost, the consensus confirms this filter delivers exceptional sonic purity for serious enthusiasts.
Know before you buy
No, the Flow C15 is designed to filter noise without limiting current draw. It maintains the full 15A capacity required for high-performance audio equipment.
The unit targets high-frequency noise and EMI/RFI interference common in household power lines. It provides significant attenuation, particularly at higher frequencies, to reduce distortion and background noise.
It is a plug-and-play device that sits between your power cable and your component. No special installation is required, though it performs best when connected to a stable, properly grounded wall outlet.
Yes, the Flow C15 is effective for both. By cleaning the power supply, it helps improve sound staging and imaging in audio systems and can contribute to a clearer, more stable picture in video displays.
The unit features a mechanically and electrically damped body constructed from specialized materials like nano-sized ceramic particles and powdered carbon. This construction helps suppress vibrations and electrical resonance that can negatively affect signal clarity.
The Flow C15 uses a standard C15-style connector, making it compatible with most high-quality aftermarket power cords that feature a standard IEC inlet.
