What's the difference between FURMAN & RGPC power conditioners? 

Richard Gray Power Company "RGPC" products store massive amounts of AC wall power in a magnetic field which rapidly collapses and expands dissipating its stored power upstream much faster and with much more power then capacitors or the power grid itself could dissipate power upstream to your system.  RGPC magnetic field coils are placed in parallel across the hot & neutral incoming AC power massively boosting current delivery to the system.

RGPC products are truly transformational once we install our "RFI EMI RIDDANCE Technology".  Video will look like you just spent another $10,000, audio like  provide a truly staggering sonic & visual transformation for the entire system with just 1 RGPC 400 or 600 in place.  In stock form, RGPC products only afford a marginal improvement at best.  

The RGPC 400 & 600 utilize the same exact magnetic field coil, model 600 simply adds 1 more duplex outlet for a total of 6 outlets.  The RGPC 1200 includes a second identical coil to feed a total of 12 outlets and store more power.  The smallest RGPC model 200 utilizes a smaller field coil with only 1 duplex outlet, which is intended only to be used with video projectors, flat panel displays, sources, not power amplifiers nor powered subwoofers.   

The Furman brand are "power conditioners".  Furman utilizes inductors and capacitors and isolation transformers placed in parallel across incoming hot/neutral AC power to draw out various bands of noise bringing the incoming AC power closer the 60Hz-only ideal reducing the amount of power supply wasted inside the components of your system by reproducing RFI & EMI noise every millisecond.  Furman products also provide a truly massive sonic & visual transformation once SE upgraded & rebuilt internally with our extremely effective "RFI EMI RIDDANCE Technology".

Best approach is to plug an upgraded RGPC into your systems wall outlet, preferably an upgraded outlet such as a Furutech GTX-D gold or rhodium duplex outlet covered by a new Furutech 104D carbon fiber over brass cover plate to shield & dissipate some airborne RFI & EMI.  

Then plug your existing power conditioner into one of the RGPC outlets or go for the best power conditioner brand, an SE Upgraded Furman. 

Performance is improved dramatically further with each TimePortal power cord added due to the end-to-end application of our "RFI EMI RIDDANCE Technology" and high grade metallurgy 24k white gold ends.


For many years, Furman has pioneered the development of AC power products for the most demanding audio, video, and broadcast professionals.  When employing FURMAN power conditioners with Power Factor correction you will immediately notice far clearer, stunningly focused sound and visual images from your system. Video presentation will be crisp with truer colors & greater gray and black level rendering.  Noticeably improved visual depth and clarity. Sonic transients will be startlingly fast with bass fundamentals that shake foundations with their weight and visceral impact. Mid and high frequencies will bloom with sweet, non-glaring ease while imaging improves dramatically, all the while remaining true to your system's inherent virtues. 

Today's power lines are plagued with RF and EMI noise. When connecting sensitive equipment to your home's power outlet, AC noise couples into your system's critical components. This AC noise masks low level signals and cripples performance. This low level content is critical because it relays the crucial harmonics and ambience in audio, as well as the depth and clarity in video. With Furman's exclusive Linear Filtering Technology, televisions, projectors, disc players, amplifiers, and processors are fed linearly filtered clean AC power. This dramatically reduces noise and power supply energy waste, ensuring consistent peak operation regardless of load conditions or the time of day. For the first time, you will see and hear your theater or audio system as it should be - uncompromised.

FURMAN powerline conditioners provide maintenance-free surge suppression assures the highest level of AC protection possible, without sacrificing itself when the offending surge is severe - no damaged equipment, no service calls, no down time.  Our FURMAN power conditioners are offered in their stock factory sealed NEW condition.  Add on The Upgrade Company's "Signature Edition upgrade" for just $499!  Performance is DOUBLED. Our unique RFI EMI RIDDANCE TECHNOLOGY strips millions of unwanted pulses from the systems AC power all of which otherwise get reproduced right along with the music & video signals. This frees up 10-100 times the available power supply energy in any given millisecond to more faithfully reproduce the intended music & video signals to STATE OF THE ART 100% guaranteed to FAR surpass ANY Power conditioner made today, even the Elite 20PFi once upgraded will surpass the most expensive power conditioners made. Without our unique RFI EMI RIDDANCE technology all other power conditioners pale. Bass response becomes THE BEST as a result, so does liquidity, musicality, ease, palpability, slam, dynamics, sparkle, depth, articulation, clarity, extremely 3D live right before you feeling on music & film is just tremendous when the rest of your system has also been SE upgraded with the same unique RFI EMI RIDDANCE TECHNOLOGY
