Don’t stop reading until you get to
the end of this article. You are in danger of
being left out! Okay, okay, I’m just kidding,
but I stumbled on to something that justifies
me pecking at this keyboard while everybody
else is outside enjoying fresh air and
sunshine. It is about audiophile bonding, man
and machine joined in a common quest as they
sail the sonic seas. This is one of those rare
times when it’s all good and I know what I
want to say, but not exactly how to say it.
Bear with me while I attempt to tell you about
my aural adventure.
L’ object D’article
Like the majority of audiophiles, each
year I see the price of high-end audio gear go
higher and higher until it threatens to price
me out of my hobby. Just like the one-eyed cat
sniffing around the seafood store, the really
good stuff is way out of my reach. I promised
my audiophile readers I would keep one eye on
the burgeoning Pacific Rim and the other eye
in this bailiwick in case something does
emerge that breaks down a long-standing price
barrier. This is one of those infrequent
events.
To begin, allow me to let you in on what may
be a not so dirty little secret: There are
American audio companies whose components are
either partially or entirely made overseas at
a lower cost and they’re not passing along any
of their savings on to you. Now before I get
further into this narrative, understand that
this report is about a really fine product
that is designed and assembled in the U.S. but
with parts manufactured in China that should
not be placed in this category. The Hyperion
Sound Design HPS-983 loudspeaker
is distributed by California-based Studio
Acoustics. The appearance of the HPS-938 is
very much like that of the better-known
$22,400 Wilson Audio Watt/Puppy 7 combination
and two or three other high-end speakers I can
think of. But the HPS-983’s shocking $4,000
price is decidedly un-Wilson like.
Because I believe that this three-way design
is good enough to compete in the same niche as
the Wilson, I will write this review in that
context. For the most part they share the same
basic enclosure design and utilize the same
number of drivers. The two bass drivers and
the tweeter are of the same size but different
in construction. Frequency response for the
HPS-938 is 30Hz up to 22kHz, sensitivity is
rated at 90dB, and its impedance is 6 Ohms
nominal. The speaker design is rigged out in
two separate parts;
the bass cabinet is a vertical rectangle with
twelve coats of hand rubbed black lacquer. The
top-mounted tweeter/midrange cabinet has the
same rich, black finish but is in the shape of
a truncated pyramid. The lower cabinet is a
bass reflex enclosure on four spike feet that
houses two 8” graphite SVF woofers placed
vertically one above the other with a
horizontal slotted port directly between the
two. The letters SVF refer to a proprietary
driver design called Synchro Vibrate Flat Top.
It refers to a design that reinforces and
stiffens the cone by using a flat disk in the
center of the cone. The top section houses a
proprietary 1” copper short horn tweeter and a
6 ½” Spider-less SVF fluid damped carbon fiber
cone midrange. This two-piece enclosure design
has grown in popularity over the last ten
years. It provides practical advantages the
most important in my book is the ability to
set up and fine tune a sound stage by moving
the tweeter/midrange cabinet independently of
the bass enclosure. It also allows you to
space the speakers a bit farther apart than a
one-piece design facilitating a larger, more
realistic soundstage.
Comparisons
While the HPS-938 may look like some
other Hi-End speakers, it has one or two
qualities that set it apart from the ordinary.
When I sat down to listen it quickly dispelled
my preconceptions about it simply being a
look-alike knockoff. On the contrary, it
performed far better than I expected. Before I
go any further with this tale, let me stop and
fill in some background about two other highly
respected benchmark “look-alike” speakers; the
aforementioned Wilson Watt/Puppy and the the
$20,000 Joseph Audio Pearl. I remember a demo
a few years ago of the Watt/Puppy 5 at a
high-end in a small and very crowded room. I
found a seat about six feet from the left
speaker. One of the demo CD’s played exhibited
a hard, glaring treble, so much so that I had
to cover my left ear. Now Dave Wilson has done
a lot since then with his newest design to
smooth out the rising treble response. The
Watt/Puppy 7 is not nearly as critical.
While the Wilson speaker has generally been
regarded is a very revealing tool for
equipment or recorded music evaluation, Jeff
Joseph’s very organic Joseph Audio Pearl plays
old analog recordings when he demos his
speakers and his speakers sound like they have
been voiced with analog. I still remember
listening through the groove noise when Jeff
Joseph played a recording of a young Louis
Armstrong singing and playing St. James
Infirmary. It was simply wonderful. Now
consider the Hyperion HPS-938. They are voiced
somewhere in between these two fine speakers.
The midrange is very similar to that of the
Pearl but the tweeter is extended or you might
say tipped up like the older Wilson but not to
the same extent. It can emphasize vocal
sibilance, but in a narrow band that does not
usually affect male voices. Mind you, it will
not reproduce sibilance if it is not present
on the recording. But on the other hand, that
very same characteristic lends itself to
ambient, airy details and a sense of
spaciousness. In a world of tradeoffs, I would
much rather see and hear into a deep and wide
soundstage that liberates me from my small
room. That is something that I value very
much; push back the boundaries and transport
me into the performance and I require little
else. Ultimately the quality that impresses me
the most is a continuous natural transition
from the lower midrange to the treble. They
offer a refined, smooth presentation that
belies the fact that they use a midrange
crossover. They remind me of the continuous
midrange of my reference Quad ESL-63
electrostatics but with more extension. It is
very significant in my estimation that the
HPS-938 can reproduce music with the same
clear, seamless, midrange voice even when
turned down and played at low volume. This
indicates to me excellent driver matching and
crossover integration.
In my Room
The manufacturer’s representative
helped me to unpack and do a preliminary
setup; I should say instructed me on how to
remove the lacquered speakers (“take off your
wristwatch”) from the triple-walled cardboard
boxes and their custom cloth Velcro secured
slipcases. I spent the rest of the time
fine-tuning and tweaking until I felt I had
done everything I could to optimize them in my
apartment’s living room. This is where I ran
into the proverbial fly in the ointment. In my
somewhat smallish listening space, in front of
an 11’ 8” wide wall, the bass towers easily
loaded the room and produced excessive low
bass. At a level equivalent to polite
conversation between three or four people the
bass remained in proportion to all the other
elements of the performance. The bass was not
a problem when I first heard them in Alexis
Park Hotel room AP2260 during the 2004 CES.
Nor did it prove to be a problem during the
promo in the parlor of the Studio Acoustics
representative.
When
I listened to Frank Sinatra sing “What’s
New” from the album Only the Lonely
[Capital 48471] the vocal inflections and
breathing sounds seemed to place him in the
room directly in front of me. The sound of the
bass line was deep and slightly warm but
replete with small details like the husky reed
sound of a baritone saxophone. The problem I
ran into is in no way the fault of the
speaker. What was needed was for my wife to
sleep on the couch while I cleared a few
things out of our master bedroom. That way I
could setup the speakers on the 14-foot long
wall of the room. I explained it would only be
temporary, two or three weeks tops until I
finished the review. Her alternative was for
me to sleep on the couch. Darn it! That would
still leave me battling deep bass room nodes.
Women are so unreasonable. They just seem to
want to personalize everything. Resourceful
creature that I am,
I still had a few tricks up my sleeve. Forced
to use alternative therapies, I used my Room
Tunes pillows and Gryphon panels on the
sidewalls and Argent Acoustic
Room Lenses around
the speakers to combat the nasty nodes. And in
case you were wondering, it worked fairly
well. I still can increase the volume from my
Audio Research CL-60 amplifier and get the
room to boom, but now it takes a bit more
energy to energize my room.
Bottom Line
I wish I could just go bananas with
these speakers and enjoy them full blast, but
alas, ‘tis not my fate. I would love to crank
up Vince Castro and play his Do Wop Bong Bong
song, Bring Back My Love and dance around in
my underwear. However, I do see two other
possible solutions for these speakers. Even
though I can only use one amplifier they can
be bi-amped or even tri-amped.
So
what if the amp driving the bass had a volume
control? That might solve the problem? Another
thought, the manufacturer might consider
giving the user some variable control on the
back of the enclosure to adjust the bass
level? Ideally if I could bi-amp these
speakers I would use a classic sounding tube
amp on the midrange and treble and a good
bi-polar, solid-state amp to control the bass.
Fortunately for me, the midrange sound of the
human voice is my primary musical reference
and does not require deep bass. So I will be
content listening to my long-standing
reference:
Basia’s Time and Tide [Epic EK-40767]
played at moderate volume levels.
It’s one thing to design a speaker and sell it
for $20,000 and quite another to do pretty
much the same thing and sell and ship it for
only $4,000. This has been a kick for me. I
almost feel like I discovered them. Yes, I
know $4,000 bucks is still not cheap, but
consider what these speakers can do in a good
room (and of course you must give them room to
perform) and then consider what the
competition costs. You will agree they are
indeed a very good deal. Remember all speaker
designers make some compromises to voice their
speakers as close as possible to what they
consider accurate. I don’t claim that the
Hyperion HPS-938 is better than the two
speakers I’ve mentioned in this report, but
the differences are not so great, while the
price tags are. Ultimately, the decision will
come down to a matter of your personal taste.
Now I wonder, is it possible for me to
nominate one’s self for a Grammy? I don’t
know, but I think it’s worth a shot. What if I
punch in Grammy on Google??
Oh, and one more thing. You can call them for
additional information or if you’re ready,
order them direct.
