First impressions mean a lot…
Most people like nice things, nice
places and nice people. Oh, and tacking on a
“new” in the front of these can also be
another bonus. Recently my wife and I moved
into a lovely new house in the beautiful
neighborhood of Maywood, NJ. These were two
new experiences for us in that we had been
married for over two years yet still owned two
individual properties that we were traipsing
back and forth between in Manhattan and
Irvington, NJ.
As physically beautiful as the new house and
neighborhood are they wouldn’t add up to much
without our beautiful neighbors who are truly
a blessing to know, and around whom to live. I
would say the people are what give the
neighborhood its “soul.” The same can be said
of any business or audio company, whereby
those who create and showcase the products,
and even those who deliver them, can influence
the soul of that company.
A case in point is one Mr. Albert Wu, Hyperion
Sounds' East Coast NJ office rep who I met
earlier this year a few months before moving
to our new home. Albert is a gentle, affable
soul who has been a pleasure to know, greet
and listen to music with at both my old and
new houses. Initially, I had retrieved a pair
of Hyperion’s now discontinued HWS – 733’s
from Clement Perry that had undergone some
tough times during transit and weren’t able to
perform to the best of their abilities as a
result of the physical damage. Albert, upon
hearing of this, decided that a replacement
pair was in order, so plans were made to make
the swap but as my schedule would have it, I
was off to Europe for another tour last
spring.
By the time I returned I was in a new home and
Albert delivered the replacement pair of the
733's but shortly thereafter Mr. Wu gave me a
call to say that there was a new model on deck
replacing the HWS-733 which was about to be
discontinued. Albert posed to me “How would
you feel about instead reviewing Hyperion’s
new flagship HPS-968 model”.
Hmm. “How would I feel??? (Something shiny AND
new?) Bring them by right away! I’ll supply
the juice and hors d’oeuvres!” (Actually my
wife did in the end, and Albert and I happily
ate them.)
Setup
Albert brought the HPS-968s over during the
early summer in an impressive 4 boxes that had
some of the most diligent packaging and
protection I have ever seen. The bass modules
were contained in a box within a box. Inside
the inner most box soft Styrofoam padding was
applied on all the walls of the container and
within laid a cabinet enclosed in a soft cloth
bag featuring Velcro fasteners. 2 Nylon straps
fully encircling each cabinet were
thoughtfully applied to the exterior of each
cloth to assist in lifting the units from
their boxes. Just witnessing these being
pulled from the boxes in all their “dressings”
was already impressive.
A kit included in each of the upper module
boxes contained the gold plated screw-on feet,
their screw lock-adjusters, binding post
jumper wire, the gold pucks that were to be
placed on top of the lower bass module upon
which the feet of the upper module would rest,
a gold screw and knob that would be attached
to the support arm of the upper module, and
attachments to secure lasers to the tops of
the upper modules to insure uniformity of the
tweeter firing direction and heights between
both channels. Altogether this kit was another
touch of class in its packaging and
presentation.
As the 968s can be tri-amped or tri-wired,
Albert, knowing that I hadn’t 4 matching
monoblocks or bi-wired cables, brought along
Hyperion’s top-of-the-line silver jumper
cables to do the duty. Albert stated that he’s
seen the best results on the 968s when
connecting the amps directly to the midrange
posts but due to the stiffness and short
length of my Straightwire Black Silc speaker
cables we had to settle for wiring the
monoblocks directly to the bass modules.
(Though less than ideal in setup I wasn’t left
with a lurking suspicion the sound was
obviously being compromised by this during my
time listening to the speakers.)
Initially Albert applied about 30 degrees of
toe-in on both speakers and the upper modules
looked to be tilted forward about 7 to 10
degrees to account for my somewhat low seating
position judging from the lower plane of each
upper module’s cabinet. As time wore on and we
received comfy new furniture (more new stuff,
hmm…) with a higher seating position, I found
that leveling the upper modules off so that
they were parallel to the tops of the bass
modules gave me the best performance. I also
flattened out the toe-in so that the speakers
were only about 5 – 7 degrees off of being
perpendicular to the walls behind them. From
the center of one channel’s woofer to the
other is about 7 feet 3 inches. My ears are
about 9 feet from each of the tweeters on
their slanted-back front baffles.
The 968s feature the ability to adjust the
tweeters in 2dB increments up to +4 dB or down
to -4 dB via a rear-mounted knob on each upper
module. After much experimentation over a good
number of weeks ultimately I chose to set the
tweeters to the 0 db level. The roll off of 2
db was nice at first but as time wore on I
decided that no attenuating or accentuation of
the highs gave me the most lifelike and
cohesive reproduction of the music. However, I
did change the power cable on my primary
listening source, a Marantz 8260 SACD player,
from an old PS Audio Mini Lab to an
ElectraGlide cable to achieve a warmer sound.
At that point I felt that I attained the most
satisfyingly neutral and balanced sound from
the system.
Interestingly enough, raising and lowering the
upper module could achieve to a lesser degree
something of a similar effect. Lowering the
height of the tilt forward to parallel to the
top cabinets sent the tweeter firing higher
into the air which gave me a warmer more
rounded sound, while raising the rear tilt up
higher forced the tweeters to fire more
directly at me gave and a more incisive and
slightly brighter sound.
Positioning and setting the HPS-968s for the
best sound is simply a matter of personal
taste. With the combination of the
electronically adjustable tweeter output
levels, and adjustable tilting upper module
containing the tweeters and midranges, as well
as the toe-in variable, the user is presented
with more options than with your average
speaker. This level of customization is
refreshing and I welcomed it as it served to
be an invaluable tool in setting up the 968s.
No longer did I have to pick a relatively low
seating position to mate with my Thiel 2.2's
for the best sound. The only possible drawback
is that with all of these options comes a
level of complexity that if not paid attention
to could end in some not so spectacular
results. But with a bit of care and attention
to detail (that most of us audiophiles do any
way) the listener can optimize the setup
according to their room and tastes.
Unfortunately, no literature or manuals
regarding setup came in the packaging of the
review sample speakers.
Fit and
Finish
The Hyperion 968s finish is a piano quality
lacquer of high gloss black. It is blemish
free, equal in appearance to that of the
highest quality musical instruments and
furniture. It surpasses that of the finish on
my well taken care of 1967 Yamaha U3 piano.
The binding posts and supplied attachable and
adjustable feet are gold. The feet themselves
are weighty, and have the feel of a high
quality, quite dense metal, crucial in
isolating the speakers from spurious vibration
energy.
The 3 pairs per speaker of massive gold
binding posts are textured to allow for a good
grip. There is one pair on the bass module and
two pairs on the midrange/tweeter module. The
posts are attached to the speakers with what
seem to be removable metal plates as there are
screws on the plates. I did not remove the
screws or remove the plates. (Perhaps with
Hyperion's approval and assistance I may get a
gander of the internals, at which time I will
report my findings.)
Hyperion
design aspects
Of most interest to me after living with the
speakers for a quite a while in my somewhat
large (15 feet wide x 28 ft & 4 inches long x
7 feet 9 inches tall) virtually untreated new
listening space (except for 4 of EchoBusters'
Corner Busters and some rather large soft
furniture) is Hyperion’s “Rear Pressure Reduce
Device (R.P.R.D.) technology, meant to
minimize the rear pressure reflection
influence." In a nutshell this technology
apparently seeks to reduce the amount of sound
coming off the rear of the speaker thus
removing the sound muddying effect of
reflections from the wall behind the speakers.
I can say without a doubt this works!
I hadn't even noticed this technology in my
initial glances at Hyperion's site page
dedicated to the 968s and just noticed it in
preparing for my final review notes. (I
actually try not to get caught up so much in a
product's technology while doing the majority
and initial phases of my listening. I feel
that getting too attached to the technology
pushes me more on the road of listening for
things in a product's rendering of the music
rather than listening to a product's
performance and in essence, losing sight of
the larger overall experience.)
After setting up the new listening room I
noticed a decline in quality of performance
with the old Thiels in place. The old house's
listening space was much smaller but it had
soft pine floors, and plaster and lathe walls
with curtains directly behind the system. The
combination of 1920's plaster and lathe (which
does sound better than modern sheetrock) as
well as the curtains gave me a reasonably warm
and focused sound back at my old home. The new
house's sheet-rocked walls proved to be much
harsher, as well as depreciated the focus in
my system. I had been meaning to address this
with some wall treatments but upon placing the
Hyperions in my room I achieved a noticeably
better focus than my old Thiel 2.2's, such
that it put my need and desire to further
treat the walls on the back burner. Don't get
me wrong, as I'm sure that extra treatments
would squeeze even better sound from my system
but Hyperion's Rear Pressure Reduce Device (R.P.R.D.)
technology worked so well it's given me some
time to wait on this.
Listening – where the fun starts
I'm going to dive in before mentioning any
specific song selections and throw out a few
descriptions of the HPS-968s from my review
notes. Hyperion's HPS 968s have astonishing
clarity, speed, agility, and faithfulness,
along with a tremendously beautiful amount of
extension on both extremes of the sonic
spectrum that serve the music to the best I've
ever experienced from a pair of speakers I've
ever had in my possession. I would even dare
to say they rank easily in the top 5 speakers
I've ever heard in my life in any setting
whether at a trade show or within a personal
system. I can confidently say the Hyperion
968s ranks up there with the finest from Thiel,
Vandersteen, Dynaudio, Wilson Audio, and
Wilson Benesch.
One of the first things I immediately noticed
was the need to set my preamp a good bit lower
in level relative to the Thiels because of the
968s sensitivity rating of 90 dB. The Thiels
are rated at 87 dB and as such are not as
efficient as the Hyperions.
On
the "Presto" as conducted by Karajan from
Beethoven's Symphony no. 7 in A Major, op .92
[Deutsche Grammaphon SACD 474 604-2] I heard a
tremendous weight and authority from the HPS
968s. The combination of an enormous amount of
speed, clarity, dynamics and gobs of textures
was rendered from the Hyperions in the most
lifelike, spine-tingling and musically
satisfying manner I have ever heard in my
system. The crescendos and suddenness of
dynamic contrast were absolutely breathtaking.
As clear and deft as the Thiels have been in
my system the Hyperion’s simply bettered them.
The Hyperion’s portrayed the back and forth
transitions from the grand bombast of full
strings and tympani down to the delicate
sections of woodwinds with violins and solo
flute in a most spectacularly dramatic and
nimble manner. The 968s, in combination with
the Nuforce ref 9V2 SE’s, performed with so
much ease in rendering of the difference in
texture AND dynamic capabilities between the
different instruments and sections that I
could easily sit back and just be amazed with
the music without ever once worrying about any
noticeable distortion or sonic anomalies.
For example at 1'25" into the “Presto” the
968s handled the decrescendo and settling of
the music with aplomb featuring less
overshoot, with more ease and flow than my
Thiel 2.2’s. There was no sign of driver
overhang and the resultant smearing of the
music. After this moment in the music the
gradual crescendo up to the capitulation at
2'32" was portrayed by the 968s with equal
effortlessness with nary a hint of strain or
glare heard in the delivery while at the same
time maintaining a phenomenal amount of
transparency.
What shortcomings that could be heard were
only those of the recording itself. For
example I could swear that I noticed for the
first time that at 3'13" in there was an edit
as evidenced by either some studio engineered
dynamics that seemed artificially softer or
the splicing of a recording which revealed a
slightly different mic placement. The fact
that I could hear these things was a testament
of the Hyperion 968s astounding amount of
detail and world class clarity.
The Hyperion 968s conveyed Carl Nielson's
Quintet for Flute, Oboe, Clarinet, Horn and
Bassoon, op. 43 mvt. III - "Praeludium:
Adagio; Tema con variazioni" [Sony
Classical, SMK 46250] with a tremendous amount
of differentiation between the individual
instruments that was surprisingly new to my
ears. Once again I heard a phenomenal amount
of texture along with a healthy dose of each
instrument’s natural overtones and harmonics
more so than that heard via the Thiel’s. I
could hear and feel the flesh of the fast
flute lines, as well as distinguish the
tonguing techniques of the player. This
hallmark served as a testament to the 968s
amazing ability to deliver both the flesh of
the unadulterated midrange and the pristine
highs of the flute.
Hyperion’s choice of employing 1st order cross
overs has paid off in spades as the 968s
imaging is stellar. The positions of all the
performers in the quintet on the Nielson were
easily noted both laterally and depth wise.
Thiel speakers have a history of being
champions in this category and the 968s
equaled the Thiel’s in this matter while doing
it with less stress and fatigue that in the
end gave me the perception of even greater
depth and focus. Overall I heard a sound that
was easily recognized as being sweeter and
cleaner, with a richer, more fleshed out and
fulfilling midrange, featuring greater purity
than my usual Thiel 2.2’s on any other speaker
that’s crossed my review bench. In fact I
could say that I’ve only heard a few times in
passing whether at trade shows or visits to
other audiophiles’ homes, this kind of purity
to reproduced sound.
On
"Africa" from The John Coltrane Quartet's
The Complete Africa Brass Sessions
[Impulse IMPD-2-168] I was treated to a more
beguiling sound through the Hyperion 968s with
a significant reduction in stress, strain, and
distortion than what I had been hearing via
the Thiel 2.2’s. All of these improvements
were there while at the same time I had a more
revealing and lifelike view of the music and
performance space that John Coltrane, his
quintet and his brass orchestra occupied. Here
the midrange was once again so captivating
that I heard Coltrane’s lines with a
lifelikeness and propulsion unlike ever
before. With the speed and clarity of the 968s
drivers, even during his fastest, most
ferocious runs I could hear EVERY note's
articulation and pitch clearly yet at the same
time I never felt any of the stress and
fatigue that so often comes with speakers that
might feature so much pace and resolution but
at the unfortunate expense of musicality.
There was a palpability, roundness and flesh
from Coltrane’s horn that pulled me deeper
into the music and elevated my appreciation of
his mastery of his horn and art even more than
ever.
As compared to the Thiels, the HPS 968s also
served up more rhythmic pace and bounce from
Elvin Jones’ cymbal beat. His
direct-from-Mother-Africa linearly rolling
tom, snare and bass drum work had an immediacy
and drive that was spectacularly portrayed by
the 968s in the closest form in spirit to
hearing him live that I’ve ever heard. Up and
down the entire frequency range of the kit I
could hear more rightness and believability in
its reproduction. Having heard Elvin play a
decent number of occasions in live intimate
settings – one time even when he sat in at the
legendary Bradley’s along with Betty Carter
with a band of young lions I sat directly next
to him inches from his hi hat - I can verify
these speakers got his vibe right.
Via the 968s I heard greater texture, timbre,
and better room cues within the recording. The
instruments of each and everyone were more
distinct with gobs more information than I had
ever heard it in my system.
I must also note that I have heard this same
recording on, our editor Clement Perry’s state
of the art mega-buck system several times as
it is a reference piece that Perry likes to
play for the jazz musicians and music lovers
who visit him, just so he can watch them well
up with emotion and not too uncommonly cry.
(The greatest thing about Perry’s choice here
of a reference is that it is purely based upon
the music and not so much some audiophile
notion of great products that ignores the
music.) With the Hyperion 968s in place in my
relatively humble system I was able to hear
this wonderful piece of great American Music
in a reproduction that held its own as
compared to Perry’s system that cost many
times more. Though surely not as resolved as
that what I heard from Perry’s $500k system, I
was still left with as deep an emotional
impact from the performance the 968s
effortlessly posited.
Perry himself heard my system with the HPS
968s in place but being driven with the
lesser, non-SE versions of Nuforce’s Ref 9
V2’s and he was similarly impressed. He even
congratulated me on having a great sounding
system to match our great new house.
David Pizaro’s organ performance of Samuel
Barber's "Adagio for Strings" from Barber's
Adagio [BMG 09026-68758-2] was warm,
enveloping as well as accurate in a way that
I’ve never witnessed before on any reproduced
performance of organ music. The low end
extension, without a hint of distortion,
played through the Hyperion 968s just simply
wasn’t possible on the Thiels as their
frequency range doesn’t extend as deep as the
968s.
This disparity in bass performance is
understandable as the Thiels are not even half
as expensive as the 968s but I’m nonetheless
impressed at the how much the relative
newcomer Hyperion has done to produce such an
amazing speaker at this price point. The extra
3k of moolah, as it concerns the 968s, gets
you a speaker that will shake you to your core
when paired with the right amplification, at
least. I must have listened to this Pizaro
performance 5 times in a row and kept turning
it up each time until I approached real-world
levels and never once noticed any driver
distortion being induced from the any of the
lowest organ notes. In fact, as I noticed the
speakers were so efficient, accurate, and
distortion free at loud volumes, I actually
became more fearful for the structure of my
house than I was for them!
Each time the music approached the 3’53” spot
of the music where a gigantic, gut rumbling,
room vibrating low E flat is played moving up
to an E natural shortly thereafter, I braced
my self for what I thought would be a driver
crackling, magnet bottoming out, stress of a
passage but the 968s sailed through this
torture test with no problems in terms of
driver breakup. I didn’t perceive even a hint
of distortion even at with playback set at
Unity Gain on my Channel Islands Audio preamp!
That huge low E flat was spot on and clearly
recognizable with none of the sub standard
one-note-bass that is the result of lesser
engineering.
I tell you, at that moment, with fear in my
heart and my thumb hovering over the stop
button of my SACD player’s remote my jaw
dropped in shock and awe (thank you Bushie for
that one!) as I heard and SAW one of the most
gigantic musical moments I have ever witnessed
in my entire life. I literally saw the
woofers’ bounce in and out from the front
plane of the cabinets like it was some cartoon
movie but it didn’t sound distorted in any
way! Whether this is a testament to the
speakers or the amps or both might be
debatable, but I have to admit I couldn’t do
this with my Thiels.
What was all the more amazing was that all
this sound and clean extended bass was coming
from a speaker that is just a bit over 3 feet
7 inches tall. That 90 dB sensitivity rating
was clearly showing its worth here. Touching
both the upper and lower cabinets during some
of the loudest passages on this selection
revealed that very little resonant energy was
being transferred from the drivers to the
cabinets on either lower or upper module.
Lovers of organ music with limited space and a
good strong amp or amps, just might find the
Hyperions 968s to be a ticket to heaven on
earth.
The
Hyperion 968s served oodles of funk n’ thump
on Erykah Badu’s "Rimshot" and "On & On" from
Baduizm [Universal, UD 53027] as another
testament to their ease in delivering the
pace, weight and authority found on this disc.
A veil was lifted from the music as compared
to anything I have ever heard in my system so
much so that I could make sense out of some of
Erykah’s previously indiscernible mumblings.
All along, the head bouncing groove was there
unlike ever before to me. In this way the
Hyperion’s once again showed their greatest
strength – the ability to disappear and just
let the music speak for itself while at the
same time shedding a new light on recordings
that I thought I already very well knew, only
to find even more luscious detail and sonic
glory within each of them.
In
closing…
The most impressive thing about the Hyperion
968s is their ability to get out of the way
electronically and let the music speak for
itself. With some care and attention on
finding the right setup for me in my own
space, great recordings sounded amazing, good
recordings sounded great and bad recordings
sounded well, merely OK through the 968s. At
the same time borderline recordings sounded
noticeably better through the 968s than
anything I’ve ever heard in my system but
still one can’t get around bad in, bad out.
Care should also be made in finding components
that have a commensurate quality to that of
the 968s but at the same time with all their
wonderful amount of resolution, the act of
changing or upgrading something as simple as a
power cable in one’s system will be readily
noticeable and just might be the ticket to
sonic bliss if for some reason these speakers
aren’t doing it for you as evidenced by my
changing of the power cord on my CD player.
Hyperion’s 968s mated beautifully in my
none-too extravagant system with glorious
results and represent a true value at their
price level. Also keep in mind these speakers
may be tri-amped or tri-wired which should
give even better performance than what I even
experienced.
The Hyperion 968s are truly a reference
quality speaker in all the most important
facets of performance, fit, finish and design.
They have marveled me in the most undeniable
way with their uncompromising musicality,
clarity and faithfulness. I have the gut
feeling that it will be quite some time before
I hear anything at this price point that will
surpass them. If any one is in the market for
a speaker below $20k (and possibly even
higher) I highly recommend taking the time to
listen and/or audition these speakers before
possibly coming too heavily out of one’s
pocket. I have a feeling they just might be
very happily impressed and surprised at their
price to performance ratio.
Bravo, Hyperion, as you have melded together
Earth and Heaven to produce a truly Titanic
speaker.
