Preface
I first learned about the Nordost power cables from Scot Markwell, who at
the time was reviewing equipment for audiophile publications in the U.S. and
abroad as well as working as Harry Pearson's assistant. The word was that they
were like no other power cables on the market.
The news surprised me, not because I thought Nordost couldn't make a good
power cable, but rather because Vin Garino of Nordost had once told me that,
besides their initial (discontinued) entry into the power cable arena, they
had no intention of creating a line of power cables. It made me wonder if an
engineering breakthrough of some sort had taken place.
I had the opportunity to catch up with Vin and Joe Reynolds of Nordost at
CES 2004. Thanks to a plug from our Editor, John Johnson, we all agreed that
I should review the power cables. As with a lot of high-end equipment these
days, initial demand had outstripped supply, so review samples were months
away. Meanwhile, I was given a copy of the U.K.'s HiFi+ that contained
editor Roy Gregory's extensive review of Nordost power cables. Roy's review
was so positive that it left my mouth watering.
My anticipation was heightened by the fact that I already used Nordost
Valhalla interconnects and speaker cables everywhere in my digital chain. I
couldn't help wondering if Valhalla power cables would further complement my
existing cables and increase the quality of my listening experience.
John initially suggested that I review the power cables via an add-on box
placed within the context of a larger equipment review. I, on the other
hand, felt that when a highly respected cable company releases a new line of
power cables, with its statement product listing for $2500 and bearing the
same “Valhalla” nomenclature as its statement interconnect and speaker
cable, that an entire review devoted to the power cables was appropriate.
In the end, John accepted my reasoning. I, in turn, acknowledged the
resistance to reviews of cabling and tweaks held by some readers of hi-fi
magazines, including Secrets. My recent review of WireWorld interconnects
and speaker cables has already generated a buzz on the Secrets cable forum,
to which both John and I have posted replies. Who knows how much more will
be shared on the subject by the time this review is posted. Hopefully
readers will refrain from personal and ad hominem attacks, and instead speak
from direct experience.
The WireWorld review recounts my first experience with comparing
interconnects, my reactions to their high prices (which in retrospect seem
miniscule compared to the price of Nordost Valhalla), and my surprising
discovery that interconnects do sound different. Actually, my very first
experience with the importance of superior cabling came much earlier in my
life.
Once upon a time, in the pre-CD era when I thought the high-end referred to
the top of the Empire State Building, I regularly read High
Fidelity and Stereo Review, mainly for the recording reviews. Besides my
Dual turntable, which was equipped with a basic Shure cartridge, I owned a
used Pioneer receiver and equally ancient Advent speakers. Hook-up was
accomplished by standard interconnects and thin, lamp cord speaker cable.
The sound was better than what I heard from my car radio, but it bore little
relationship to live music. But since I had no idea that a home system could
begin to achieve the engaging reality of live performance, I was content to
make do.
Then, one month Julian Hirsch penned a comparison review of speaker cables
and came to the conclusion that speaker cables don't make a difference. I
read every word, put down the magazine, and found myself questioning what he
had said. Determined to find out for myself, I visited an electronics supply
store and came home with either 14- or 12-gauge silver-plated speaker wire.
It cost $0.25/foot. The stuff was so thick that it was hard to connect to the
receiver. But once I had done the best job I knew how, I took a listen. My
jaw dropped as I heard what sounded like an extra octave of bass and far
more body than ever before.
Perhaps 25 years after that initial experiment with speaker cables, tens if not hundreds of
thousands of audiophiles invest in high-end cables, with many upgrading on a
regular basis. Such organizations as The Cable Company allow potential
customers to borrow different cabling and experiment at home before making
purchases. Unless everyone investing in such products shares the same level
of mass delusion, it seems reasonable to at least entertain the possibility
that cables do make a difference.
Back to direct experience. When I loan distinctly non-audiophile friends
interconnects and power cables to try in their systems, they invariably
report back that they hear differences. A recent demo of a pair of used Tara
Decade
interconnects at the home of a confirmed jazz lover elicited the comment,
“Now that finally sounds like what I hear in clubs.” My reply was that when
he also upgraded his speaker cables from lamp cord to something decent and
tried an aftermarket power cable on his receiver, he would probably discover
that his mass market system and very old box speakers sounded better than
what we commonly hear over the lousy sound systems in most clubs.
I know that it is more than reasonable to ask why and how, if our residences
are wired with thin, sometimes heavily corroded wiring, the last few feet of
wiring could possibly make a difference. I'm not an electrical engineer, and
cannot offer a technical explanation. (I'm sure others can). All I know for
certain is that those last few feet, as well as the quality of power they
carry, make all the difference in the world. Install a separate line in your
residence dedicated solely to your audio equipment, make sure it is
well-grounded into the earth, borrow a well-respected power conditioner and
power cables, and take a listen. Any one of those four things will make an
audible difference. Put them all together, and you'll be amazed at how much
more involving and rewarding your listening experiences will become.
Introduction
When Joe's package of two Valhalla and three Vishnu power cables arrived
from Nordost, I was surprised to discover a relatively small, lightweight
box. Accustomed to thick, often unwieldy power cabling - my sizeable Elrod
cords were shipped in 4-6 foot long containers - I expected a container at
least the size of a major power amplifier.
Disbelief increased as I opened the package. The Valhalla power cables, with
their transparent outer shielding and red, black, and silver innards
measured 7/16” thick. The lavender Vishnus were approximately 5/16” in
diameter. How could such thin power cables trump the Elrod EPS and EPS
Signatures that powered my components?
I immediately put the two Valhalla power cables on a pair of Parasound Halo
JC-1 monoblocks (review coming shortly), and left them cooking for days on
end. Nordost had assured me that 48 hours break-in time was sufficient, and
I was sure that Parasound's power-hungry amps would do the trick.
In retrospect, I question whether such a short break-in time is sufficient.
(My experience is that most cable manufacturers understate the amount of
break-in time necessary in order to not scare off potential customers.) Over
the course of a month of use, the sound I have heard through the Valhallas
progressed from flat, dull, and dry, to shiny bright albeit monochromatic to
its current level. I remember at one point lamenting that while the top was
as transparent and vibrant as all get-out, there was precious little body
and bass. As you will read below, that is NOT the case once these power
cables are broken-in. Had I drawn conclusions based on my initial
experiences with the cabling, you would be reading a very different review.
As a result of the sonic transformations that occurred as the Valhallas
continued to break-in, I spent far more time breaking-in the Vishnus. I
first daisy-chained all three together via some neat adapters, plugged them
into the nearest outlet I could find, and connected the last Vishnu to a 150
watt light bulb. I left the cords cooking for 8-10 days. With the Parasounds still
going full blast, I decided not to bring up the subject of the electric bill
with my spouse.
The flexibility of the Nordost Valhalla power cables, their 2 meter length,
and the fact that, once they are fully broken-in, they don't require days on
end to sound their best, has made comparison and contrast relatively easy to
accomplish. As you will read, I have tried virtually every possible
combination and permutation of cable placement available to me. With an
equipment chain consisting of a PS Audio P600 power plant, heavily modified
and upgraded Sony transport, Theta Gen. VIII DAC/preamp, and either a single
Jadis Defy 7 or two Parasound Halo JC-1 monoblocks, careful comparison took
a considerable amount of time. Only after several weeks of such
experimentation, invitations to several friends to share feedback, and
enough plays of Rachmaninoff's Symphonic Dances to contemplate
violence, I'm ready to provide a report.
Listening
Up until now, my power cabling has consisted entirely of cords by David
Elrod. At first, I used a full complement of EPS-2s and -3s. As much as I
loved those cords, assurances from Jim Weil of Sound Applications and David
himself that the EPS Signatures would provide far more body and bass heft
led me to slowly replace all but one of my EPS -2 and 3s with EPS Signature
2s and 3s. Everything was ultimately powered by Signatures save for the
Jadis amp, which was powered by an EPS-3.
I had grown quite satisfied with the Elrod cords. A recent decision to move
my Talon Khorus X Mk. II speakers off their spikes and suspend them on the
same Ganymede ball bearing supports I use under the rest of my equipment
enabled me to decouple the speakers from the floor, resulting in far clearer
bass. No longer dependent upon the width of my carpet to protect the
hardwood floor from spike damage, I was able to separate my speakers by 12
feet. As a result, the soundstage widened, depth increased, everything
became more realistic sounding. This led to even greater appreciation of the
Elrod combination.
Then along came the two Valhallas. After they had broken in, I put one on my
Jadis amp. I was initially confused by what I heard. While the bass was
definitely substantial, everything sounded thicker and heavier than I wished
it to sound. Was this the fault of the Valhalla, I wondered?
Further experimentation led to my discovery that the EPS Signatures, at
least in my system, tend to increase body, midrange, and bass impact while
simultaneously darkening the top. (I discovered the same effect with the
AudioPrism SuperNatural S2 and many of the mostly discontinued Shunyata
power snakes I've reviewed.) This never disturbed me before because the
final Elrod cord in my chain, the EPS-3 on my amp, balanced out this
darkening effect by lightening bass and adding clarity on top. This enabled
me to hear a good deal of the heft of the Signatures without the darkness
and heaviness that became apparent once the EPS-3 was replaced by a Nordost
Valhalla.
It is essential to note that I have never heard the Elrod EPS Statement or
S2 Statement II in my system. These huge $2700 power cables are in the same
price range as the $2500 Valhallas and the only fair comparison with them. I
did hear the EPS Statements in the Audio Aero/Joule/Joseph Audio room at CES
2004, and thought the sound one of the best at the show. The darkening
effect of many cables in the $1500 range - the EPS Signatures are $1600 -
may vanish with the $2700 EPS Statement. I encourage listeners to try the
entire range of Elrod power cables, which I consider some of the best on the
market.
What I needed to do was lighten things up. I tried the second Valhalla first
on the Power Plant, then on my transport, last on the Theta Gen. VIII. In
each position, it replaced an Elrod EPS Signature.
It was on the transport that the second Valhalla had the most impact. All of
a sudden, I heard a level of deep bass, sparkling highs, three
dimensionality, transparency, and air that I had never before heard on my
system.
The change was anything but subtle. It was impossible to miss. The
soundstage opened up, for the first time approaching the sense of
boundlessness I experience in Davies Symphony Hall. There was an extra level
of resonance, a greater awareness of the sound of the hall brought about by
the Valhalla's stunningly transparent window. (I can barely imagine how good
this system will sound when the extra resolution promised by new digital
formats becomes available to me via Theta's anticipated DVD-A/SACD upgrade
for the Theta Gen. VIII and Compli transport.)
I also experimented with adding two Vishnus to the mix. An hour or two of
musical cables followed, as I jockeyed Valhallas and Vishnus back and forth
between Power Plant, transport, Theta, and Jadis. My final conclusion is
that the $600 Vishnu definitely shares with the Valhalla an extraordinary
transparency and sparkling clarity that approach what I experience up close
in live concert settings. What the Vishnu does not transmit is the sheer
weight and bass extension of the Valhallas. For many audiophiles, combining
one Valhalla on the transport or power conditioner with Vishnus on other
components may deliver all the transparency, clarity, brilliance, and heft
they desire.
While auditioning the phenomenal Parasound Halo JC 1 monoblocks, I put
both Valhallas on the amps, my usual EPS Signature-3 on the Power Plant, and
my usual EPS-Signature 2 on the Theta. On the transport, I variously tried
the Vishnu ($600), the WireWorld Silver Electra 5 ($750), and the PS Audio
X-treme Statement (variously listed for $400 and $500).
The WireWorld had the most bass heft of the three, and was quite transparent
and alive on top. The Vishnu conveyed a shade less body and heft, but its
highs (e.g., cymbals, piccolo, triangle) rang out with a three-dimensional
vibrancy and additional degree of transparency that came much closer to the
magic that I experience in live situations. With the Vishnu/Valhalla combo,
sounds literally hang and glisten in space in a most thrilling way. The PS
Audio conveyed the bass heft, but the top was darker than both the WireWorld
Silver Electra 5 and the Nordost Vishnu, the window a bit clouded, and the
presentation a bit murky. The sense of subtlety that I experience from both
Nordost power cables was not to be had.
The $2500 Valhalla, of course, offers all the thrill, vibrancy,
transparency, and subtlety of the $600 Vishnu as well as the size, weight,
and bass heft of a $1600 EPS Signature. For audiophiles who want the
ultimate in extension and musical involvement, the Valhalla is the way to
go. Those who have heard the equivalent of Mahler's Das Lied von der Erde
from the center of Row H Orchestra of Davies Symphony Hall, or Mahler
Symphony No. 2 from Row K Orchestra will especially appreciate what the
Valhallas can do. They are, in a word, stunning.
Other Listeners Weigh In
Before writing this review, I invited two people over to join in a final cable
comparison. The first visitor, my friend Alan, knows nothing about high-end
audio equipment, but everything about the experience of live music, theater,
and dance. The second, John Beavers, is a new acquaintance poised to write
his first review (of Wolff power cables) for Positive Feedback. Alan brought
along EMI's Mariss Jansons conducting Shostakovich's chilling Symphony
No. 11, and John brought a Telarc disc of veteran bluesman Pinetop
Perkins plus two of his favorite Wolff power cables. I was quite intrigued
to discover what two men of very different backgrounds would say about the Nordost power cables.
First we auditioned the system using my usual complement of Elrod power
cables. Listening to Pinetop Perkins, John found my system a little drier
than he was accustomed to. He thought the vocals and piano sounded okay, but
the highs less extended than he preferred. Alan thought the sound
(meaning the timbre of voice and instruments) pretty natural.
On the Shostakovich 11, I was taken by the excellent depth and natural sound
of the presentation. I also thought the sound somewhat veiled and only
moderately transparent. Alan thought the sound quite natural but missing
some air. (I was astounded to discover a distinctly non-audiophile speaking
“our” language!) He commented that since the symphony's subdued opening was
meant to describe the open space of St. Petersburg square, a more open sound
would have greatly enhanced his enjoyment. John echoed Alan's
dissatisfaction with the lack of air. (Both men, I might add, were quite
taken with the excellence of Reference Recordings' aforementioned
Rachmaninoff Symphonic Dances, by far one of the best orchestral
discs for auditioning equipment I have ever encountered.)
Then I replaced the Elrod EPS-3 on the amp and the EPS Signature-2 on the
transport with Nordost Valhallas. An EPS Signature-2 remained on the Theta, and
an EPS Signature 3 on the Power Plant.
With Valhallas powering the transport and amplifier,
I discovered the Rachmaninoff more open and transparent. I wrote “Highs
shimmer a lot more. Bass more solid." Alan commented, “More air, space and
three-dimensionality. This sounds more alive.”
John's comment deserves a paragraph by itself. “To be brutally honest,
before you put the two Valhallas into the system, I wasn't enjoying it very
much. It was hard on my ears; it just felt like ‘recorded music.' The
Nordost Valhallas brought things to life. There was a sparkle on the high
end and the cymbals. Dynamics were more impressive, quicker and
hard-hitting.”
On Alan's Shostakovich 11, I thought the opening drum rolls sounded so much
clearer than before. The additional air was apparent. The offstage drums
rolls were also clear, no longer sounding like a feeble wind machine. The
soundstage seemed so more open and boundless. Alan was taken by the
largeness of the space. Again I quote, “I never enjoyed your system much
before. Now the brightness doesn't have an edge to it.” John thought the
timpani had more snap. “The main thing I hear is much more clarity.
Everything springs into focus.”
On Pinetop Perkins, what struck me the most was how well I could hear the
inner quality of the voice. The Valhallas provided a clearer path to the
soul of the man, of which his voice was an extension. John felt everything
sounded more natural. We both agreed that we could now clearly discern that
the piano was an upright, not a concert grand.
Time for a switch. With the Vishnu replacing the Valhalla on the transport,
the Valhalla replacing the EPS Signature 2 on the Theta, the second Valhalla
remaining on the amp (I'm never going to remove it if I have anything to say
about the matter), and the usual EPS Signature 3 on the Power Plant, John
felt the music less potent, with the voice losing some of its character. I
found the Shostakovich flatter sounding, lacking mystery, plainer and less
involving. Alan thought he could live with the sound, but preferred the former
combination of cords.
Another switch. This time, the Valhalla on the transport, the Vishnu on the
Theta, and the remaining cords where they were. For me, the all-engrossing
sense of mystery returned, as well as a lot more clarity and heft. Alan heard more
clarity on high violins, John found the music more natural to listen to.
Then we returned the Valhalla to the transport, the EPS Signature 2 to
the Theta, the second Valhalla on the amp, and the EPS Signature 3 on the
Power Plant. Alan heard more space
and air, John more warmth. I again confirmed that the EPS Signature 2 has
significantly more body than the Vishnu, but at the expense of transparency
and ultimate high extension.
Note from the Editor: At some point, we shall
bench test power cables for impedance values and include the results in our cumulative
table. I know there are some of our readers who will go immediately to the
Secrets Forum after publication of this review to criticize the idea that
power cords make any difference. I don't know if I could hear any
differences myself, as I have never really sat down to compare power cords. But I
intend to have Jason prove it to me on his system, single-blind with generic
power cables included. I will report on the outcome. If there are
differences, they are probably due to extremely low capacitance, but that
discussion remains for the future.
8/20/04 -
Here are the results of my listening tests with Jason's system, a photo of
which is shown below:
I could
indeed hear differences between different AC power cords, but they were very
subtle. When I told Jason what I heard, he agreed and explained in more
detail. What was interesting was that the generic $3 AC cord came in a tie
for second place with the Nordost Vishnu, and ahead of another expensive AC
power cord. The difference was one of small transients at the beginning edge
of such things as guitar plucks. I can't explain how this is happening, but
it did happen. Frankly, I am very surprised, but I am still not absolutely
convinced, as this was not a single-blind test, and the differences were not
dramatic. I knew which cords were being used, so it still could be
psychological. Nevertheless, I heard differences when I had anticipated
hearing none. The next step will be to have a group of people listen in a
blind test. This is a much more complicated procedure and will take some
time to organize and execute, but it will be done at some point, perhaps
with the Bay Area Audiophile Society. In the
meantime, I now have some Valhalla and Vishnu power cords so I will measure
their impedance values compared to other cables we have on hand.
Conclusions
If you're like me, you may have just cut to the chase by skipping the above
details. I encourage you to read them, because they're quite extensive.
If you have read them, I shall simply paraphrase and elaborate upon what I
wrote above.
The Vishnu, which at $600 is far less expensive than many power cables on
the market, offers a level of transparency, vibrancy, immediacy, and
resolution I have never before experienced from a power cable in this price
range. It does not offer ultimate bass heft or extension. But what it does
convey, it conveys with lightening speed and the highest degree of
musicality. Its strengths are second to none. All the undertones and
overtones are there. It is a wonderful cable, a perfect complement to the
Valhalla.
For audiophiles who want the ultimate in bass and treble extension
as well as musical involvement, the Valhalla is the way to go. The bass is
marvelous, the size and weight lifelike, the soundstage seemingly boundless,
the window as clear as can be. Highs shimmer, bass pounds with lightning
fast speed. Those who have heard the equivalent of Mahler's compositions
performed in
a top notch concert hall will especially appreciate what the Valhallas can
do. They are, in a word, stunning.
