I have commented over the years about some of
the stunning products coming out of Asia which
offer great sound, wonderful aesthetics, and
thoughtful design. Companies such as Xindak,
Vincent (Shengya), and the Opera Consonance
line of products are just to name a few. Now
comes a couple more companies from this
rapidly growing high-end giant, JAS Audio out
of Hong Kong and April Music out of Korea.
Both JAS Audio, manufacturers a full line of
high-end quality amps, preamps, loudspeakers
and more, and April Music, who have also
developed the Stello and Eximus brands, are
being made available in the U.S. by one of the
true nice guys in audio, Stephen Monte of NAT
Distribution.
Over the past several months I’ve had the
opportunity to listen to a couple of products
from these two companies: the JAS Audio Orsa
loudspeaker and April Music Aura Note
CD/Completer. Originally, I listened to each
these pieces by themselves as part of my
reference system in my main listening room,
but while they both did fairly well on their
own, I soon found out that they are absolutely
brilliant when coupled together.
In fact, let me get straight to the point. If
you are a dyed-in-the-wool audiophile who is
always at a loss for a down-to-earth system
that you could heartily recommend to
non-audiophile friends, or are about to send
one of your kids off to college and want them
to have a high-quality, wonderful sounding
music system that won’t need to be setup on
crates or take up much dorm room space, or
even if you just wanted to have a great
looking (extremely high Wife Acceptance
Factor) and sounding music system for a formal
living room or family room, you need look no
further. The Orsa/Aura Note system delivers
drop-dead gorgeous looks, wonderful sound, and
a boat load of features in a package that is
affordable (just under $5k) and takes up about
as much room as a laptop computer.
The Orsa
I’ve seen the Orsa referred to as JAS Audio’s
“entry level” loudspeaker. If you’ve read my
previous review of the Argento Audio Serenity
cables, then you already know that I have a
big problem with the phrase “entry level.”
Believe me, at a price of $2,495/pr, and with
the level of craftsmanship and parts used in
the Orsa, there is nothing entry level about
it.
The Orsa is a two-way design that uses a pure
aluminum 4 ½” twin ribbon tweeter made by LCY
of Hong Kong and a 6” paper cone
midrange/woofer made by Morel. It also uses an
adjustable crossover and all internal wiring
is silver. The cabinets use real wood veneers
with multiple layers of piano-grade lacquer
for an outrageously gorgeous finish. The
tweeter and midrange/bass components are
housed in separate enclosures and internal
bracing is extremely solid. The overall size
of the Orsa is 16 ½” x 9” x 13 3/8” (HWD) and
each weighs in at 24 lbs. The frequency
response is a deceptive 45 Hz – 60 kHz (they
sound bigger). Their sensitivity is rated at
88 dB and their nominal impedance is 8 Ohms.
The front baffle of the woofer enclosure is
sloped to improve phase/time coherency. The
tweeter adjustment helps make in-room
placement of the Orsas “idiot-proof.”
Before
coupling the Orsas to the Aura Note, I
installed the Orsas in into a system
consisting of the BAT VK31SE preamp and VK1000
mono amps, and Classe CDP502 CD player. I
began by listening to a disc that I fall in
love with at the start of each Christmas
holiday season (basically, the day after Labor
Day), Vince Guiraldi’s A Charlie Brown
Christmas [Fantasy]. Track 2, “What Child
Is This,” is jazz piano at its finest. I had
never been able to appreciate it more than
when hearing it on a tweeter such as the
ribbon design used in the Orsa. The intricate
sound of soft piano hammers hitting the
strings of Guaraldi’s piano seem to dance from
the Orsas and replicate an extremely lifelike
and immensely enjoyable sound. I enjoyed this
tune so much that I must have repeated it over
and over for nearly an hour. The same can be
said of the ultimate Peanuts track, “Linus and
Lucy.” I must have heard that tune a million
times during my life (what boomer hasn’t?) and
never realized just how wonderful a piece of
music it is. This is the beauty of
rediscovering old favorite discs via a pair of
highly revealing loudspeakers.
The Aura
Note

The Aura Note, though called a “CD/Amp
Completer,” is easier to think of as an
integrated, top-loading CD player and 50 WPC
stereo receiver.
Of course that would be short changing it as
well because it also has USB inputs for MP3
player and PC connection, an AUX input for TV
or DVD connection, and a headphone jack. The
Aura Note was designed for April Music by
British industrial engineer Kenneth Grange.
Grange is discussed on April Music’s website
as being “… co-founder and partner of
Pentagram from 1972 to 1999. Grange
specializes in product design and corporate
identity. Among his projects are for example
the National High Speed Train, the Kodak
Instamatic Camera, Wilkinson shavers and
Parker fountain pens. On top of that, there
have been many jobs for Japanese customers,
more than 100 products for Kenwood and the
design of the last London taxi.
Kenneth Grange has received a number of
important awards, among which are the Duke of
Edinburgh's Prize for Elegant Design, the
Design Council Award and the Master of Faculty
of Royal Designers for Industry.
Among others, he obtained honorary doctorates
from the Royal College of Art (1985),
DeMontfort University (1998) and through the
Prince Philip Designers' Prize (2001). In
1984, Kenneth Grange was appointed Commander
of the British Empire.”
Grange’s knack for aesthetically pleasing and
functional design is evident here as well. The
Aura Note oozes elegance with its chrome
chassis accents, simple sliding tempered glass
CD player top, unobtrusive footprint and
credit card thin, 24-button, 27-function
remote control.
Physically, the Aura Note measures just 11” x
3” x 11” (WHD) and weighs a respectable 15
lbs. The top two-thirds of the chrome
faceplate hold a row of eight function buttons
for standby (power), volume (up and down),
play/pause, skip/stop and mode. It also holds
the infra-red sensor and an easy to read LED
display window that shows the selected input,
CD track number, track time and even acts as a
clock when in standby mode. The bottom third
looks like a black anodized heat sink. All in
all, the Aura Note has a very stylish look
that should compliment any décor. The rear of
the units holds the gold-plated speaker posts
and single-ended AUX input, a Type B USB input
for connecting a PC, AM/FM antenna
connections, and an IEC power cord receptacle
which allows you to use after market power
cords. The right side of the Aura Note
includes a ¼” headphone jack and a Type A USB
input for connecting MP3 players and even an
iPod. On second thought, let’s just stick with
calling it a CD/Amp Completer. I can see one
of the lovelies popping up on university
campuses across the country. Of course at
$2.5k a pop, I can also see them walking away
from a lot of universities as well. Maybe the
folks at April Music can find a way to install
a “LoJack” on these things to make them easily
recoverable.
Internally, the CD section features Cirrus
Logic CS4398 DAC and top-loading disc drive
system. The amplifier section employs a 50wpc
Mosfet single-ended push/pull amp with a
Hitachi J162/K1058 transistor per phase. All
circuitry is neatly laid out on an “L” shaped
circuit board that is isolated from the
chassis. Power comes from a fairly massive
toroidal transformer. The AM/FM tuner section
features presets for 20 stations though I had
some difficulty getting more than a handful of
stations locked in to any satisfactory degree.
Fortunately, one of those stations was the
local National Public Radio affiliate (WBEZ
91.5 FM). Readers of some of my previous
reviews will know my affection for a good live
FM broadcast and few stations deliver better
than NPR, particularly its Saturday night
offerings, A Prairie Home Companion and
Michael Feldman’s Wha’d Ya Know? Each week
Wha’d Ya Know features a great jazz interlude
by the Wha’d Ya Know Band featuring John
Thulin on piano, Jeffry Eckels on bass, and
Clyde Stubblefield on drums. Thankfully the
Aura Note does a great job of locking this
station in.
System
Setup
I have a second listening room in my home
specifically for evaluating modestly sized
systems. It measures about 12’ wide x 10’ long
with 8’ high ceilings and is open to my
recreation room on the left side. It has a
carpeted floor and the walls are painted with
a flat finish to minimize sound reflection.
The Orsas sat atop 24” high, sand-filled
stands built by Tyler Acoustics. The stands
were coupled to the floor beneath the carpet
via spikes. The Orsas were connected to the
Aura Note via Stealth Audio Petite Dream
speaker cables. The Aura Note sat on a
sand-filled Premier equipment rack that was
also coupled to the floor via spikes. The
Orsas were not difficult to position in this
room. I got the best results with the speakers
about 30” from the rear wall, with my seated
position about six feet back from there and
with my ears about level with the tweeters.
Lately, Max, my two-year-old Boston terrier
has supplanted my girlfriend as my listening
session partner. Aside from an occasional
tendency towards flatulence, he makes for a
very pleasant companion.
Listening
After making sure that the Orsas and Aura Note
were fully settled in I began to evaluate them
as a system. The synergy between the two was
instant. “Musicality, musicality, musicality,”
was the first thing that came to mind after
listening to the soundtrack from the Herbie
Hancock documentary, Possibilities [Warner
Brothers]. Many jazz “purists” have panned
this disc as nothing more than mass market
junk because of its connection to Starbucks
and pop idol guest performer list which
includes John Mayer, Sting, Carlos Santana,
Christina Aguilera, Johnny Lang, and Annie
Lennox. The opening track, a duet with Mayer
called “Stitched Up,” is a ballsy, and
flat-out charming tune that has been
constantly at play both in my car and home. In
fact, every track is great fun to listen to
including the somber “Hush, Hush, Hush”, with
Annie Lennox. I must also admit though that
the best parts of each song are the Hancock
solos, which through the Orsa/Aura Note system
are eloquent, wonderfully rendered and
penetrating. This is a fine recording.
Sade’s Lovers Rock [Epic] was another
recording that benefited greatly from the
cozier confines of my smaller listening room
and the prime attributes of the Orsa/Aura Note
system, that being its ability to portray fine
details in realistic space and dimension.
Particularly the acoustic guitar playing of
Stuart Matthewman on track eight, “Every Word”
and Sade’s sultry vocals on the title track.
The Orsa/Aura Note system, when not tasked
with trying to fill a large room, work
together to get the most out of your
recordings and reward you with sound that is
textured, palpable and very musical.
Ah, but let’s face it, this system,
particularly the Aura Note, was designed with
MP3/iPod crowd in mind as well and they don’t
always listen to Herbie Hancock and Sade. Fact
is, they never listen to Herbie Hancock and
Sade but they do often listen Wyclef Jean. One
of his best recordings from the past few years
was Masquerade [Columbia], particularly track
13 “Two Wrongs.” This song balances out Wyclef’s distinctive voice and Reggae/HipHop
beats with the sexy voice of Claudette Ortiz
and some nice guitar work by Wyclef. Of course
there’s also a tank load of bass too and the
Orsas handle it well. As I mentioned earlier,
the Orsas sound bigger than their size and
specs would suggest. This entire CD is full of
bass heavy beats that never lost their
musicality through the Orsa/Aura Note system.
Conclusion
Though I felt these two pieces were better
discussed as a combo, make no mistake that
each is an excellent performer in its own
right. The JAS Audio Orsas were very effective
when paired with the far more powerful BAT
amps though the ribbon tweeter got to be a bit
edgy on more dynamic recordings. Likewise, the
Aura Note did well driving my Escalante Design
Freemonts though their dual 12” bass drivers
proved to be a bit too much for the Aura
Note’s 50 watts, especially on some of my R&B
recordings.
But paired together, and in a room with
moderate dimensions, they are capable of
reproducing music that is far more lifelike
and enjoyable than you’d think possible for a
sub $5k system. For those of you who place a
high importance on integrating music into your
lifestyle without giving up all your living
space, this is the system for you. Whether you
listen to your iPod, CDs, or MP3s and whether
you listen with headphones or from your laptop
PC, these products offer enough features,
functions, great looks and sound quality to
turn any non-audiophile into a music lover. I
would heartily recommend the JAS Audio Orsa
loudspeakers and April Music Aura Note
CD/Completer as individual components but
together, they were a revelation.
