Power Clarifier

The improvement is immediate and significant.
The music is more detailed, lively and dynamic.

To running a top-end hi-fi system via iSUPPLY power system. The improvement is immediate and significant. The music is more detailed, lively and dynamic. The "silence" is at a lower level, the transients are cleaner and more relaxed.

The 10 Power Ringleaders

There are at least 10 distinct types of power problems, which we  refer to as the "power ringleaders", that can negatively affect your audio equipment. Effects range from audible noise or hum in your components, loss of dynamic range, reduced quality of sound or video, slow burnout of components, loss of presets, complete loss of sound or picture, ruined recordings, burned out video projector bulbs, speaker damage, all the way to the complete destruction of electronic circuits leaving nothing but smoke and charred ruins.

Many audio power conditioning products have addressed either a single problem (such as surge arrestors) or only a few of the problems. These products are designed to reduce the effects of one or more of the ringleaders, but none have offered a fully effective solution to the full range of power problems. While some are effective at their intended task, a surprising number have made extravagant claims of effectiveness, or promise sound system improvements based on questionable engineering principles. Others operate so efficiently that they are unable to deliver the full current required by high power audio equipment. INCRECABLE iSUPPLY power system is the ONLY technology that provides one perfect solution to eliminate most Power Ringleaders. 

Of course, we are fond of pointing out that its a bit difficult to  diagnose exactly which ringleaders have crept into your power lines - without a $5,000 power quality meter to tell them apart. Just to  make gremlin hunting even more sporting, the brownout gremlin you chased away on Thursday morning may be replaced by his cousin harmonics gremlin Friday afternoon. The perfect gremlin free week you experienced in May, will be utterly overrun in July when your neighbors turn on their air conditioners. It is a bit self serving, we admit, but isn't it obvious that the clever solution is to skip all the partial solutions and simply go for the technology that wipes out all ringleaders?

1. Blackouts  
    A total loss of utility power
 6. Brownouts
     Reduced line voltage for extended
     periods of a few minutes to days
2. Frequency variation
    A change in frequency stability
 7. Sags
     Short term low voltag
 3. Transients
     Instantaneous high voltage increase 
     in the range of nanoseconds
 8. Electro Magnetic Interference (EMI)
     Often referred to as noise
 4. Harmonics
     Distortion of the normal waveform
     transmitted by non-linear loads.
 9. Radio Frequency Interference (RFI)
     Also a high frequency waveform -
     often referred to as noise

GBC Grounding Box Power Clarifier

The enclosure is based on a double chassis made entirely from metal. This creates a perfectly closed shield, protecting the inside filter and power distribution system from RFI noise. The main element of the GBC-6 Power Clarifier is a set of passive filters and a unique system of voltage distribution to the separate sockets. The noise from the power grid is filtered in a circuit using low inductance capacitors and over-current and over-voltage limiters in the form of audio grade resistors. The whole circuit is mounted in a double-sided PCB with DCT3 Silver Ion Plated 6N OCC or DCT3 pure silver wire of high cross-section. Separated wiring for each of the sockets guarantees an even and stable power distribution, regardless of the load on each of the sockets. The power strip is also equipped with three LEDs signaling proper function and a polarization detection circuit signaling proper power line polarity or grounding problems.



  • Polarizing Filter PZT is designed to work from 10k Hz upward which is the frequency band that affects the sound and video quality.

  • PZT filter can reduce 95% of total noise in AC line.  Zero Cross Filter OXF each duplex has the special filter circuit to reduce the interference generated by equipment plugged into duplexes from one duplex to other duplex, ensure the purity and cleanness of AC line delivered to equipment. 

  • Star Wiring Technology is special technique which totally separates the wiring to each duplex. This will reduce the crosstalk between duplex and increase maximum current delivered to the equipment. Separated Preamp, Integrated Amp, Power-Amp, Turntable, Phono Amp, CD Transport, DAC & Media Player outlets

  • DCT3 Pure Silver and Silver Ion Plated SIP 6N OCC cable for internal wiring

  • DCT 4N OFHC US Power Duplex

  • DCT 4N OFHC IEC power input

  • DCT Gold plated metallic output-brackets providing ideal GND to GND and GND to case electrical contacts.

  • Grounding Point Function for Digital and analog components

MSRP:  1,485 / set

Burn-In Period
All GBC-6 have been tested and pre burned-in at the factory. However, as with any high end audio components, it may take up to 50 hours of listening to music to reach the optimal sonic results.
** Due to continuous product improvement, actual product might be varied from product's picture.
