Conversation with Sunny Cable’s Sunny Lo
tell me about Sunny Cable?
Technology specializes in the design and
manufacture of the world’s most time-accurate
cables and loudspeakers. Uh … what else can I
tell you? Ask me another question please.
CP How new is
Sunny Cable Company?
SL: Sunny Cable
Technology was officially registered in
Orinda, California in August 2004. However, my
research on cables started some time ago in
1997. It takes a long time to first understand
the basic science of cables and to find out
what actually happens when electricity is
passed through a conductor. Then I tried to
develop solutions to the problems and ran
experiments to see if my thinking was correct.
My initial solution was complicated,
extremely labor intensive and also very
expensive. So I spent many months trying to
improve on my design. Once I was certain that
I have a successful solution, I knew I had to
patent it first before I bring it out on the
market. Then I still needed to find ways to
reduce cost and simplify the production
process but without sacrificing performance.
And that’s why it took so long. Anyway, we are
CP: What makes
Sunny Cables “Time Accuracy” sonically
superior to others?
SL: Well, “Timing
is everything!” Isn’t it? You see, a typical
musical signal is actually comprised of high,
mid and low frequency components. In order for
us to hear this signal and feel that it does
sound realistic and accurate, we have to hear
ALL these frequency components at their
PRECISE moments in time. In other words, each
and every frequency components of the signal
must be transmitted without timing error;
otherwise we would hear a sound somewhat
different than the original one in the
Now, some people might argue that since
electricity travels near the speed of light,
why would there be a problem? Theoretically,
this might sound correct. But what they don’t
realize is that electricity needs a conductor
for transmission, and all conductor materials
have their own limitations in physical
properties that prevent them from performing
at their theoretical maximum capabilities. So
those theoretically infinitesimal differences
in time now are magnified into milliseconds of
timing errors, which our brain could
My time-accurate cable design drastically
reduces timing errors with my patent pending
technology. That’s why our cables are
CP: I understand
the Sunny Cable is a patent pending design.
Without having to give away
too much, can you describe why?
SL: I really
don’t want to reveal the secrets and details
of my design. You know. When the patent is
finally issued, then you’ll know that it’s
really different. The important thing is: does
the design really work? If not, then even if
the patent were issued, it would still be
There is a Theory section on our website. If
your readers are interested in finding out
more about my design, they can get rather
detailed information from there.
CP: What are
Sunny Cable’s sonic attributes?
I can't detect any except
for it leaning ever-so slightly on the warm
side of neutral. Does this technology
have a sound?
SL: Aha! The
beauty of my cables is that they have no sound
characteristics of their own. Some cable
designs attenuate the highs and lows and call
the remaining sound “musical”. But cables are
supposed to be passive, not “colored”. If you
prefer a certain characteristic sound, get an
equalizer but insist on using the most neutral
cable you could find.
Some other cable designs exaggerate the
high end at the expense of the low, and they
call it ”analytical”. Sure, it might seem that
you are hearing more “details”; but should
violins sound like they were played with steel
strings? And what happens to bass music then?
And home theater? No wonder explosions sound
more like firecrackers! And do you want to
change cables just to match the music you want
to play? Every time?
And there are cable designs that emphasize the
lows and attenuate the highs in order to make
small, bookcase type speakers sound fuller in
bass. But if you use these cables on larger
speakers, they would sound boomy.
You see, you cannot create more music than
there actually is. Look at it this way: you
have a glass full of water, representing 100%
of the music. Now, you are supposed to pour
this water into three empty glasses labeled
High, Med and Low – meaning frequencies of
course. No matter how you pour the water, you
cannot end up with more than one full glass of
water that you started with. Well, you might
not need to divide it exactly into one-third,
one-third, one-third; maybe 35%, 33% and 32%
or some minor variations would be fine, but
certainly not 50%, 30% and 20%. You simply
cannot get accurate and realistic reproduced
sound with this kind of ratio.
Maybe I have given a long answer to your short
question! Anyway, the best sonic attributes a
cable should have are no attributes at all! If
I were happy about “musical” or “analytical”
cables, I would not have started my research.
In fact, I could easily tune my cables to get
these “sonic attributes”. I mean, it took me
many, many months of testing and experimenting
to find the right materials and their correct
arrangement to get rid of “sonic attributes”
and achieve the truly neutral quality I want
for my design.
CP: Have you
found no one else that uses this similar
technology? If so, who?
SL: I haven’t found
anybody using similar technology in this
industry. I know for sure no one used it
before I did; otherwise, my design would not
be patent-able. And I don’t want to see
anybody else uses it now because that would be
an infringement on my patent rights.
CP: How then did
you discover this technology?
SL: Like I said
earlier, I did research starting with the
basic understanding of what happens when
electricity (signals are electrical in nature)
passes through a conductor. Only with this
completely open approach could I discover the
real problem and its solution. Had I tried to
follow the same path other cable designers
did, I would have missed it too.
CP: There are
many companies that boast low distortions
through minimal capacitance, inductance and
mechanical resonances. Why do you claim your
designs to offer a greater significance in
boasting is one thing; delivering is another.
First of all, I found that capacitance and
mechanical resonance do play a part in
affecting accuracy, but only to a lesser
extent. Inductance is the main culprit! I
would say that inductance probably accounts
for about 80% of all problems affecting
accuracy in signal transmission through a
cable. If you can really eliminate inductance,
you basically solved the problem. The rest is
just icing on the cake.
The only effective way to drastically reduce
inductance is with my design. I tried to keep
capacitance low too, but it is not necessarily
to go to the extreme. I also have my own
proprietary ways to dampen vibration and
control mechanical resonance.
Whether my ways are better is easy to prove
with an A vs. B direct comparison. I’d welcome
any challenge to compete in a fair and open
What other products can we expect from Sunny
Lo as a result of this new invention?
already have three models of loudspeakers
developed with the same time-accurate cable
technology and design philosophy. I gather
from people who have listened to my speakers
at CEDIA, Rocky Mountain Audio Fest and also
at CES that they were really amazed by the
clarity, the accuracy and realism, and
especially the dynamics and fast transit
response. Some audiences have said that ours
are the most realistic reproduction of sound
that they have heard at the shows. My people
told me that they saw some guys actually duck
in response to what’s happening in the movie
because our home theater demo is so realistic.
Anyway, you can expect to see more models of
loudspeakers from us this year.
Where does Sunny Cable expect to see
themselves in the next five years?
Well, I do hope that more and more people will
try our products. Especially when they see
honest reviews from respected and open-minded
critics like you, they might be more receptive
of our new ideas and invention. And once they
try our cables, chances are that they would
Where do I see us in the next five years?
Probably expanding to Japan, Asia and in
Personally, myself and
Mike Wright and Key Kim
found the Sunny
Cables to be the best we’ve heard as well as
among the most
expensive. Why is the
Supreme so pricey?
Thank you, Mike and Key
too, for your kind words, Andre and I really
We do have more affordable reference cables –
our 1000 and 600 Series. Of course when you
compare our cables to each other, the Supreme
Series will beat the 1000 Series, and the
1000s will beat the 600s. You really don’t
need to use all Supreme cables, unless you
insist on having only the best and are willing
to pay for it. There are cables on the market
with prices not much lower than our Supremes.
When you compare the performance, it would
make our Supreme cables seem like a bargain.
I estimate that our 1000 Series could achieve
over 70% of the performance of our Supreme
cables. In terms of performance per dollar,
our 1000 Series is a best buy.
Now, I dare say that if used appropriately,
our 600 Series cables would be enough to beat
all other reference cables on the market.
Again because of drastically reduced
inductance the 600 Series is a really
value-priced reference cable.
In future, if I can find ways to lower our
production costs, I’d be happy to lower the
prices of our cables. One thing is certain
though: I will not cut costs if the
performance of our cables would be affected by
CP: Thank you Mr. Lo.
