Many pioneers of the audio industry have borne the brunt of a reluctant and skeptical customer base, and have
faced the risk of rejection bravely. If lucky, they also stand to reap their trailblazing visions. In those days,
unlike the vastly advanced iterations in today’s cable products, high-end audio cables were just beginning to
replace the chicken wires and were understandably crude in concept, design and implementation by today’s
standard.
In today’s world, cable design has become a field where advanced fabrication facilities matter profoundly
more than a technician’s mere technical competency, as designing cables of originality and superiority in the
present day calls for not only talents with disciplines in electronics engineering and metallurgy, but also the
resources as provided by precision, automated manufacturing facility.


Out of a universe of cable companies, Furutech is among the very few with in-house manufacturing capability
which has also developed its own cable design processes and technologies, as well as establishing itself as
a complete solution provider in cable accessories, offering everything from 96% lead-free “High Performance”
solder to complete cable products, and from 20-ampere “High End Peformance” duplex receptacles to
complete AC Power Distributor products. Combined with the sheer expertise, quality and scope of its product
offering, Furutech distinguishes itself from other cable sellers in the world.
For the reader who has read my recent review of Furutech’s High End Performance Reference Series cables,
you would have an idea on the extent of efforts to which Furutech dedicated in pushing the envelope in cable
design and manufacture. Now, we shall discuss two other significant product offering from Furutech: the $980,
e-TP 609 15-ampere AC Power Distributor, and the $1,045, 1.8-meter Power Reference III power cable.
e-TP609
Not incorporating an isolation transformer and the attendant circuitry, the six-receptacle e-TP 609’s chassis is
constructed from a single solid aluminum block via CNC machining, and is among the most diminutive and
exquisite-looking AC filter I’ve seen, weighing only around 6lb and not much larger than a box of Kleenex.
Furutech’s top AC filter is the $1,500 e-TP4+4 Twin Power Distributor, which is equipped with four 20-ampere
duplex receptacles and four 15-ampere duplex receptacles. The e-TP 609 is Furutech’s top 15-ampere
Power Distributor.
Furutech identifies numerous elements as detrimental to the preservation of the musical AC waveform, such
as high frequency power supply noise from other audio equipment, radiated high frequency digital noise from
DACs and digital cables, distortions at the extremes of the AC waveform as created by switch-mode power
supplies, and ground noise, voltage spikes, etc. Furutech is of the opinion that such myriad of noise can
render audio reproduction of high frequencies to become “flat, hard and grainy”, with “a thick and bloated
midrange, fat uncontrolled bass, and loss of air and soundstage stability...” The e-TP 609 was created as a
measure in countering the contaminants before they could get into the audio system.
Whereas the predominant approach to noise elimination as adopted by many high-end audio companies is
via transformer-coupled filtration and isolation, Furutech takes a fundamentally different approach using an
exceeding abundance of exclusive technologies to achieve the goal of AC waveform preservation.
First, the e-TP 609 Power Distributor’s special-grade aluminum chassis provides the first shield against
Radio Frequency Interference (RFI), which is augmented further by Furutech’s proprietary, Electromagnetic
Interference(EMI)-blocking Formula GC-303. Formula GC-303 is a 3M compound that Furutech adopted for
bonding to the “interior bottom-plate of the chassis that absorbs EMI generated by the internal fittings of the
unit.” AC resistance is further kept to a minimum with no additional filtering, allowing for the reproduction of “a
more resolving, powerful, dynamic and colorful performance from your components.”

Second, the e-TP 609 is wired with Furutech’s 12-gauge α-22. Then, three of the 0.8mm phosphor bronze α-
Conductor “Furutech Hyper Quality” FP-20A[R] High End Performance Duplex Receptacles are independently
wired to the High End Performance FI-09[R] IEC Inlet.
The third and most ingenious and remarkable feature of the e-TP 609 is undoubtedly Furutech’s own, patent-
pending Axial Locking System, which comprises an auxiliary spinal support underneath the six FP-20A[R]
duplex receptacles to counter and withstand the downward force created by insertions. Then, the duplex
outlets are further dampened individually with a special 3M substance. Per Furutech, “Each Axial Lock is
torqued to perfection to work with the 3M resonance control material, with 4 spikes provided to mount the
entire unit.”

The Power Reference III’s conductor is made of 49 strands of cores of three 0.32mm-thick α (Alpha)
conductors braided together, each core then measuring 2.5mm thick, which are then insulated with
polyethylene PE for capacitance reduction, while doubly shielded from radiated noise by two layers of flexible
PVC sheaths, which are then wrapped in Nylon-yarn, braided jacket.
The Furutech FI-25(R) IEC and FI-25M(R) power connectors fitted to the AC cable’s ends are both rhodium-
plated to counter magnetic interference, whereas the female connector is of the phosphor bronze material,
and the male connector is of pure copper.
Finally, Furutech’s exclusive wire clamping mechanism eliminates the soldering process and provides
supposedly for firmer contacts to facilitate pure and stable transmission.
Standard length of the Power Reference III is 1.8 meters.
The Working System
CD transports that were experimented with the Furutech e-TP 609 Power Distributor included the $7,500
Audio Note CDT-Three, the $9,995 Wadia 270se, the $9,380 Oracle CD 2500 which Ed Momkus reviewed,
and finally, the $26,800 47 Laboratory PiTracer. DACs rotated with the e-TP 609 were Audio Note’s $59,00
DAC5 Signature and the $29,000 DAC5 Special, as well as Wadia’s $9,995 27ix v3.0. Preamplifiers
observed with the e-TP609 included Audio Note’s $50,000, 3-chassis M10 linestage, the $10,000 M5 phono
and Nagra’s $8,995 NL-L linestage.
Initially, the e-TP 609 was plugged via a generic AC cable into a standard household AC outlet located on the
side wall , which is adjacent to the front wall adorned with 4 Isoclean ICP-003G 2-position wall outlets. This
generic power cable is the kind of standard issue provided by all equipment manufacturers in their product
packaging. I assume no Dagogo reader is still using the old chicken wire power cords for his/her audio
system.
In this initial stage of auditioning, the generic power cables were first employed to power the associated
equipment directly from the standard household AC outlet, contrasting sonic variances obtained when running
from the e-TP 609 to the associated equipment.

Power Reference III
Furutech’s top AC cable, the Power
Reference III, incorporates the same
Formula GC-303 compound for
blocking electromagnetic interferences,
only this time the technology is
manifested in an encapsulated, modular
form over a certain point of the cable.
A fourth, unique technology applied to the e-TP 609 is Furutech’s exclusive
Alpha 2-Stage Cryogenic and Demagnetizing Process, which uses the
liquid N2 high-end refrigerant at its first stage to remove stress from all metal
parts by freezing them cryogenically, resulting in a re-alignment of their
molecular structure. Sekiguchi Machine Sales Co., Ltd’s patented Ring Demagnetization treatment is then
employed in the second stage to maximize the treated metal parts’ conductivity by way of a thorough
demagnetization.
For CD transports, the Audio Note displayed the highest consistency
in improved tonal contrasts while drawing AC from the Furutech
Power Distributor. With the e-TP 609, the exquisite tonal clarity of
instrument groups from Mobile Fidelity Sound Lab’s Holst - The
Planets Ultradisc UHR™ multichannel SACD was at once more
clearly defined with a reduction in timbre irresolution. Brass sections
of this hybrid SACD/CD sounded more real with a more intense
sense of dimensionality and presence.
Substituting the two generic AC cables with two of Furutech’s Power
Reference III highlighted the brass sections of Saint Louis Symphony
with an immaculate bite and sheen that was devoid of an otherwise disconcerting, mechanical artificiality.
JVC’s year-2004 XRCD24 treatment of the 1960 RCA’s Living Stereo LSC-2369 Tchaikovsky Symphony
No. 4 is another prize to behold. The enhanced spatiality as reproduced via the Furutech e-TP 609 and Power
Reference III served as much a testimonial toward the monumental efforts of the original RCA producer John
Pfeiffer and recording engineer John Crawford, as much as it is toward the modern Japanese JVC team of
producer Kazuie Sugimoto and mastering engineer Hiromichi Takiguchi.
The acutely recreated spatiality became the cornerstone for displaying the Boston Symphony Hall’s beautiful
acoustics, in addition to a demonstration of delicate instrument texturing captured by RCA’s continuingly
relevant recording technology of the 60’s. If only we could also have Deutsche Grammophon’s same-period
recordings go through the JVC XRCD24 treatment, as opposed to the German label’s own Original-Image Bit-
Processing technique.
The same Japanese JVC team also produced the RCA Living Stereo LSC-2545 Beethoven “Appassionata”
& “Funeral March” Sonatas, performed by the legendary pianist, Sviatoslav Richter. The sound of piano as
captured by RCA’s studio of the 1960’s is not as clear, layered and vibrant as what the company’s German
SWR-Studio of Freiburg can achieve in Evgeny Kissin’s present day piano recordings. Yet, the Furutech
technology allowed more intrinsic sonic properties of the 1960 recording to emerge from the Audio Note CDT-
Three CD transport, validating the viability of similarly archived music.
Effectiveness of the e-TP 609 and Power Reference III was also dependent on individual component’s power
management scheme. While Audio Note’s CD transport exhibited the most sonic improvements with the
Furutech system, 47 Lab’s PiTracer and Oracle’s CD2500 yielded relatively miniscule level of improvement to
the presence of the Furutech.
Both the 47 Lab CD transport and Oracle CD player/transport employed outboard power supplies, with two
Humpty’s on the PiTracer and one outboard unit on the Oracle. As my personal experience on these fine units
suggests that they are fundamentally immune to AC irregularities, it remains a curiosity that if the isolation as
accorded by the substantial power supplies also would neutralize changes in AC properties as effected by the
Furutech system.
The Wadia 27ix v3.0 Decoding Computer responded to the
Power Reference III with a slightly more energetic top-end,
conducive to reproduction of orchestras, and yet showed no
reaction to the inclusion of the e-TP 609. Audio Note’s two
DACs which are extravagantly equipped with a multitude of
inter-stage transformers and radiometal C-core output
transformers persisted in their respective performance
envelope regardless if it was the Furutech or the Harmonix
Studio Master power cables transfusing power from the AC.

My concession here is that I couldn’t bring myself to plug a generic power cord into any of the Audio Note’s,
and I suspect neither can anyone of us bring himself/herself to do that, when even the lesser AN DAC costs
$30k, although Peter uses generic power cords on his products at every show. How ludicrous.
Similar findings were also prevalent on preamplifiers with outboard power supplies, such as the Audio Note
M10 and the Nagra NL-L.
Power amplifiers, on the other hand, exhibited less gratifying results with the Furutech system, with subdued
dynamics being the sole aberration. With that said, the Furutech e-TP 609 and Power Reference III system
was the only AC treatment accessories I’ve encountered that did not introduce sonic artifacts. In fact, whether
the Furutech system was powering the $25k Harmonix Reimyo PAT-777 SET, the $9k Linn Klimax Chakra
500 Twin, the $10k Audia Flight 100, the $3k Luminance Audio KST-150, or the Accuphase E-550 and Krell
KAV-400xi integrated amplifiers, there were consistently more spatial and tonal cues coming forth in the
interaction.

The only exception emerged when the $12.5k MaxxHorn Immersion horn loudspeakers
continued to produce bold and majestic dynamics as driven by the Furutech-coupled
PAT-777, Klimax Chakra 500 Twin, KST-150 and E-550 respectively. This speaker’s
100dB/8Ω-sensitivity might have constituted the one necessary condition in a mutually
complimentary treatment of the amplifiers with the Furutech devices. Based on this
observation, if speaker efficiency is indeed a determinant, then massively more robust
AC cables running between the AC outlet and the e-TP 609 may be the solution for all
Furutech-coupled amplifiers to amplify the signals with full dynamics through in
increased number of speakers of various efficiencies.
This latter prospect may also contribute to another aspect of the Furutech technology,
as I discerned a diminished benefit whenever more than two power cables of different
makes were plugged into the Power Distributor. In addition, although power cables
from other makes did yield various sonic properties with the Furutech Power
Distributor, it becomes a choice of priorities at this point, of whether a Furutech
customer wants to preserve the consistent advantage of a purely Furutech experience,
or to obtain a new kind of sound through a coop of the Furutech Power Distributor and
other company’s AC cables.

CONCLUSION
No less than 3 active power management systems had graced my home since 2005, and to varying degrees
they all introduced sonic characters of sorts while enhancing certain aspects of the audio experience.
The Furutech e-TP 609 Power Distributor and Power Reference III AC cables represent a revolutionarily
passive approach to realizing our system’s potentials, striking a sharp contrast to other companies’ goal of
system enhancement via active conditioning. In short, the e-TP 609 acts as a gravitational core for the
absorption of EMI, and once in action, its ability to captivate rampant interferences was revelatory.
Concurrent application of the company’s own Power Reference III throughout with the e-TP 609 on most
equipment with onboard power supplies represented a compounded sonic dividend for a superbly refined
sonic experience. The combined strengths of the e-TP 609 and Power Reference III yielded colossal sonic
gains in the form of less-fatiguing spectral presentation with no loss in tonal intensity, more exposed low-level
details in higher micro- and macrodynamics contrasts, higher level of ambience retrieval and spatial
recreation, and finer textural presentation.
The Furutech power management system of e-TP 609 and Power Reference III are the only sonically non-
invasive AC augmentation devices I’ve used, constituting a new standard in signal refinement. That, in my
opinion, is likely to induce a love/hate state of mind from audiophiles because of its non-invasive nature.
Depending on the needs of respective Dagogo readers, if your goal is an enhancement of your system’s
capability via active means, then the market is in huge abundance of what you need to help you reach that
goal. Yet, if you have never experienced the Furutech system, chances are you have probably never heard the
true sound of your equipment.
