PROLOGUE

Nearing the completion of this review, my wife and I paid a short visit to the
residence of Audio Note's U.S. Distributor, Ray Lombardi, in Southern
California's Simi Valley. 380 miles from my home, Simi Valley is several
thousand feet above sea level on the far side of a mountain range that the
southbound I-5 runs through from the plains beneath, endowing the town with
some degree of freedom from the cold and thick fog as spring arrives. Atop
this picturesque town of noted firemen and policemen population, Ray's
residence occupies the best lot in his community and his listening room has a
window to the open country outside.

Ray has a pair of the $19,500, top-of-the-line AN-E SEC Silver in lacquered
piano black, positioned well into the listening area with slight toe-in. His
system consisted of Audio Note's latest $40,000 dual-mono M-10 line stage
with two much larger power supplies for the 2 channels, a pair of the $22,000
"Shinri," 10 Wpc, 300B monoblocks and a $25,000 Transrotor "Tourbillon"
turntable fitted with a $6,000 Clearaudio Master TQI tonearm and $3,950
AN-Io II cartridge. Cables were the Audio Note Sogon throughout, and five
Argent Lens guarded the AN-E SEC Silver in concave from the left of one
speaker to the right of the other. I was treated to several of Ray's 45-rpm
special-release collections, including Louis Armstrong's "St. James Infirmary,"
Simon and Garfunkel's "The Boxer" and "Cecilia." Those recordings were in
plain but thick jackets.

As a non-contact medium proponent, I was surprised at the demonstrated
dynamics of this vinyl and vacuum tube-based system. Its agility, swiftness and
most of all, an excellent bottom-end, one that I did not know could be
developed by such a system, along with its ability to conjure up a most
spectacular soundstaging feast and delicious tonalities, simply astounded me.

The loudspeaker used, the AN-E SEC Silver loudspeaker, is the subject of
this review. It is a biwirable, 2-way vented design featuring a 1-inch dome
tweeter and an 8-inch woofer, with the flare port at the lower rear. According to
Audio Note's proprietor, Peter Qvortrup, the AN speaker evolved out of the
classic Snell A/II, the sound of which he admires and trusts to such extent that
he uses several pairs of the speaker as reference to reinforce behavioral
consistency in his full-range AN-E's.

Being well-aware of Audio Note's longstanding reputation as a manufacturer
of some of the world's best and most exotic vacuum tube amplifiers, I remain
curious at the British company's loudspeakers, as AN had never presented
the product line as a major offering. As the SEC Silver expands upon the
AN-E/D, readers are encouraged to read the review for a broader perspective.

Audio Note's products have exceptionally long model life as Peter undertakes
continuous refinement of a proven design with progressively strategic and
thorough incorporation of superior parts. This concept is evident in the M3
Preamplifier, which is available in the progressively augmented M5, M6, M8
and the recently introduced M10 versions of that basic platform. In addition,
AN adheres to the exclusive "Comparison by Contrast" design concept, which
aims at reducing audiophilia boredom by creating products that not only excel
at differentiating natures of various hardware and software, but will also
spotlight the differences as well.



AN-E SEC SILVER

Ascension of Audio Note's $2,700 "Entry Level" AN-E/D loudspeaker to the
"Level 5" AN-E SEC Silver represents progressive elevations of the base
AN-E. The $2,950 "Level 1" AN-E/L replaces the internal, 99.99% pure
copper AN-D single conductor speaker cable in the AN-E/D with the 99.99%
pure copper litz screened double conductor cable. The $3,350 "Level 2"
AN-E/SP involves drive units matching plus incorporation of the 99.99% 15
strand silver litz single conductor cable, while the $3,850 "Level 3" AN-E/SPx
improves upon the SP with the double conductor SPx. The $7,500 "Level 4"
AN-E SE provides customers with drive units matched with the tightest
tolerance.

Finally, at the supreme "Level 5," there is the $13,500 AN-E SE Silver that
takes the AN-E SE and equips it with silver wired voice coils, silver tuning
capacitors and inductors. Then, the AN-E SEC Silver tops it all off with
ALNICO woofer magnet. My wife started to jitter in witness of all the silver, and
I am keeping an updated list of the jewelry and silverware in the house. The
one overriding potential of having all these premium parts in a speaker is the
speaker's anticipated superior ability in converting electrical signals as
delivered by the speaker cable into mechanical energy at the highest level of
fidelity.
 
 
Each AN-E SEC Silver is a product of extensive labor. According to Peter, a
master technician spends hours matching a crossover to each AN-E SEC
Silver driver meticulously and painstakingly in order to achieve a variance of
no more than 0.1dB in a stereo pair, which must also be within a remarkable
0.2dB variance from the reference SEC speaker curve. The AN-E SEC
Silver's exterior is largely identical to the base AN-E/D, which is essentially a
large, wooden box, except that the review pair was finished at no extra charge
in the optional Madrone over gloss lacquer that encapsulates the entire
cabinet, covering the surfaces over joints seamlessly. In finishing the optional
Madrone lacquered cabinet, a skilled craftsman applied 8 layers of hand
polished polyester piano lacquer to the speaker. For the same money, I
wouldn't have any other finish.

When one compares the $19,500 AN-E SEC Silver to other similarly priced,
well-respected competitors, such as the B&W Nautilus Signature 800,
Martin-Login Prodigy, Sound Lab A1+, Tannoy Churchill, Wilson WATT
System 7, etc, the modest size of the AN cannot be overstated. These other
speaker systems sport large, visually stunning appearances, with numerous
drivers in the B&W, a large concentric tweeter/bass driver in the Tannoy and a
large radiating area in the case of the Sound Lab ESL panel.

Generally speaking, it takes an immense cabinet or an active subwoofer to
generate and sustain bottom-octave output, and a considerable number of
drivers to achieve a full range presentation at realistic volumes. I have always
believed that the more accurately a speaker can reproduce the sound of an
1812 cannon in its complexities and might, the more capable the same
speaker will be in reproducing the delicate tones of music instruments. My
Klipschorn, with its horn tweeter and midrange and 15-inch bass driver in a
folded horn system, for example, excels at delivering the dynamics of an
event, while my 4-way 7-speaker Genesis VI with its servo subwoofer system
is incomparable in the presentation of an extended spectrum.

According to an email from Peter, AN favors 2-way designs because

"
getting two drivers to work together so the overtones when present are
distinct and join coherently to the fundamental is extraordinarily difficult and
getting three drivers to do this is virtually impossible.
"

Peter Qvortrup's position is that his loudspeakers are musical instruments
dedicated to music playback, and are not to be abused with sound effects
reproduction.



REVIEW SYSTEM SETUP

The two 10-inch high, sand-filled steel speaker stands that AN supplied with
the AN-E SEC Silver were identical to the ones used in the AN-E Review,
except that bottom spikes were removed and the miniature, speaker-coupling
upward spikes were replaced by Blu-Tack. The stand elevated the AN-E SEC
Silver's to the point where my ears were parallel to the midpoint between
tweeter and woofer.

According to Joe Cutrufelli of JC Audio, one of AN's Northern California
dealers, in his visit to Peter Qvortrup's England residence he noticed the
AN-E SEC Silvers were placed at corners for bass reinforcement. JC
demonstrated a similar arrangement with a pair of AN-E SEC Silver in his
house for me, and I heard unprecedented bottom-end resolution from the
AN-E SEC Silver with a stable center image. However, after trying the same
setup in my system, I ultimately deemed the placement a departure from
personal preference in soundstaging, dimensionality and spatiality.

I found the AN-E SEC Silver's soundstaging to vary with playback of in-studio,
jazz recordings and those of orchestral pieces performed in larger spaces.
While I considered classical music to be best served with the AN speaker 48
inches away from the back wall and 14 inches from side walls, the realization
of a symphony's tremendous scale and atmosphere in this setup was
inadvertently unfavorable to the preferably intimate, livelier dynamics of jazz
music. Experimentation with toe-in angles did not yield mutually inclusive
results.

Thus, my final permanent positioning of the AN-E SEC Silver was
approximately 9 more inches into the room, 14 inches more from side walls
and then 10 feet away from the listening position with only slight toe-in. This
closer proximity of the AN-E SEC Silver accorded exceptional focus to jazz
music without over-dampening spatial cues in classical pieces.
   
   
AUDITION

Deutsche Grammophon's first SACD, a 1977 reading
of Beethoven
Symphony No. 9 [DG SACD 471 640-2]
was arguably captured at the height of Maestro
Herbert von Karajan's artistic brilliance at the time of
the recording. Here, re-mastered in DSD, the Maestro
and the Berlin Philharmonic sounded more energetic
than the same partnership's fuller-sounding, more insightful 1984 digital
version. While the DG SACD sounded less opulent than pure DSD SACDs,
such as Michael Tilson Thomas and San Francisco Symphony's
Mahler
Symphony No. 1
 [San Francisco Symphony 821936-0002-2], the DG SACD
nevertheless exhibits unprecedented tonal abundance and dynamic contrasts
superior to the CD.

With the M3/Klimax Twin hybrid amplification system, the AN-E SEC Silver's
liberation of the DG SACD's top-end was infused with a seemingly limitless
upward extension sans brittleness. Portrayal of vocals and instruments was
rich in harmonics and reverberations even at demanding volumes, and the AN
speaker's voicing of the SACD's mid to high frequencies was dense in
resolution and uncompressed in dynamics. Rich instrumental harmonics would
seemingly always find their way to the AN regardless of playback levels,
consistently culminating in a finesse unmatched by my others speakers, with
the especially noteworthy absence of ringing and screeching. While my
$9,500 Genesis VI's ribbon tweeter exhibited a highly resolute top-end, it also
unleashed minute, occasional treble edginess and a less complex harmonics
impression, contributing to artificiality inescapable in the presence of the
AN-E SEC Silver.

In that regard, the AN-E SEC Silver's mid to top-end sonics were the most
resolute among any speakers I had on hand, presenting an experience no less
than revelatory.

In rendering bottom-end octaves, AN's singular 8-inch woofer was out of
league among the likes of the trio of Genesis' 400 Wpc, active subwoofers.
Therefore, heavy bass content, such as double bass information sounded less
impacting and less substantial from the AN. Yet, the Linn-driven AN-E SEC
Silver demonstrated expertly responsive transients, which accorded the
speaker's vented, ALNICO-equipped woofer system with a tonal vibrancy that
speaks volume about the realness of instruments. Double bass had an
unprecedented liveliness of being both incisive and lingering throughout
passages, and snare drums were inclusive of massiveness with discernible
presence amidst activities onstage, casting addictive spells on its listener.

The AN-E SEC Silver's presentation at once fell into place with the
WE300B-equipped Loth-X JI300 integrated amplifier in the loop, as the AN
attained a top-to-bottom spectral fullness, producing the most layered
soundstaging and evocative instrument tonalities I've ever experienced.
Whereas the M3/Klimix Twin tube and solid-state hybrid system was
victorious in garnering the most resolute top and bottom end to my
experience, the integrated Loth-X was more refined in harmonics and
texturing than the M3/KT combo, with less emphasis in dynamics and
spatiality. Nevertheless, there was an exceeding flamboyance in sonic
coherency that not only conveyed a lifelike event, but also vanquished the
drivers of the AN-E SEC Silver into a most refined and unified entity. In that
sense, the AN-E SEC Silver attained characteristics of instruments like no
other speakers have.

Although Peter Qvrotrup associates soundstaging characteristic with
improper spectral emphasis and adamantly ventures to rid his products of the
abnormality, the AN-E SEC Silver had such broad coverage and exacting
recovery of the frequency spectrum that good recordings were never deprived
of their dimensionality.
Take The Stokowski Sound [Telarc CD-80129, now
renamed
The Fantastic Stokowski], for example, the
Loth-X driven AN-E SEC Silver cunningly laid out the
orchestra in "Bach: Toccata & Fugue in d minor" in a most
satisfying, orderly manner; one that did justice to Maestro
Leopold Stokowski's transcription of the original organ
version. The tonal fullness of the AN accorded the Cincinnati Pops with an
immensity unfound in the mannerisms of other speakers, one that
communicates not merely localization of instrument groups, but also an
unimpeded being of them, contributing to an utmost palpability. Telarc's
renowned, sonorous textures were also undeniably a crucial factor.
   

The AN-E SEC Silver's rendition of jazz was insightful with
either M3/KT or JI300 amplification. Take Audioquest's
BluesQuest [AQ-SACD1052] SACD sampler, for example,
which contained 12 highly accessible blue tunes of
exemplary sound that ought to make the sampler a
bestseller. The M3/KT coupled AN-E SEC Silver possessed
a rolling force of such fundamental nature that bass and
guitar beats, as well as organ rhythms, propelled the
performances in a most lively and satisfactory manner. More importantly, the
Klimax Twin's expeditious transients and definitive tonalities were instrumental
in endowing the captured events with a most indispensable presence.


The Western Electric 300B equipped Loth-X JI300 integrated amplifier
admittedly induced less of those pulsating factors from the AN-E SEC Silver
than the M3/KT combo. Yet, the Loth-X coupled AN speaker nevertheless
exhibited rhythm of such continuity and a sound of such liquidity, that no other
speakers in my possession driven by any other amplification could claim
equivalence.
   

As good as the AN-E SEC Silver was in rendition of classical
and jazz, it was phenomenal in portraying the pipe organ
in the CD,
Cantate Domino [Proprius PRCD 7762]. Rather
than reproduce in full force the formidable magnitude of the
organ, a task best tackled by the Genesis VI's trio of active
subwoofers or that fabled column of bass drivers in
Genesis 1.1, the Loth-X driven AN-E SEC Silver made the pipe organ an
extraordinarily expressive instrument from the organist's fingers. As incapable
as the AN was in generating and sustaining the scale and bottom-octaves of
the pipe organ, the speaker was otherwise exemplary in portraying the
instrument in every other area, such as the dynamic contrasts, harmonics
complexity, transients response and volume capability.


Via the M3/KT combo, the AN-E SEC Silver's rendition of this CD was
incredibly forceful and yet still managed to retain tremendous tonal delicacy
and incisiveness, in addition to a much appreciated weight and zeal. Their
profound conveyance of an advocacy of the tubed M3's tonal abundance and
the Klimax Twin's tonal delicacy/incisiveness and power was most efficacious
and persuasive albeit a less articulate and commanding punch when
compared to the Genesis active subwoofers.

It was during passages with this CD that I realized I could no more relate my
past Mass attendance experiences to the sound of the AN-E SEC Silver than
a video of identical events. For being part of a live event removes me from the
rejuvenating magic of the AN-E SEC Silver in the comfort and control of my
home, and video feeds inundates my senses with everything but the spirit of
the performance.

47 Laboratory's 4706 Gaincard S Dual Mono Integrated Amplifier
represented an attempt to remove as much electronics from the signal path as
possible. The AN-E SEC Silver's ability in conveying the Gaincard S's
resultant subtleties and texturing surpassed all speakers at my residence.
Whether the 47 Lab was delineating a tidal orchestral passage, a sublime
piano lamentation or lively jazz, the AN speaker constantly injected vastly
varying sonic landscapes in vividness that no other speaker could. In this
regard, the AN-E SEC Silver was like a perfect sheet of paper reacting
intensely to a drop of color working its way through the fibers in a beautiful
metamorphosis.

One enhanced form of the AN-E SEC Silver came to be when I supplemented
its bottom-end output with the Genesis' trio of active subwoofers, crossing at
the 20 Hz threshold and standing approximately 2 feet away from the side of
each AN. With judicious output levels on the Genesis, the overall presentation
of the AN/Genesis system was one of tremendous impact at my normal
listening volumes. The solid bottom-end foundation accorded by the Genesis
subwoofers not only made the AN a stunning, full-range champion. But it also
added extra dimensionality on instruments such as double-bass, cello and
piano. Yet, nothing is perfect, and circumstance did arise when a slightly
higher cut-off frequency on the Genesis, stemming from greediness on my
part, spoiled the overall presentation with incoherent top-to-bottom tonality.



SUMMARY

One of the many vital tasks the Ultimate Loudspeaker must achieve is to
convert all electrical signals into mechanical energy to the fullest extent.
High-End loudspeaker manufacturers around the world have ventured boldly
and courageously to create such a loudspeaker with every resources and
intrinsic innovation at their disposal, from cabinet designs to transducer
developments.

Despite the greatly varying approaches and techniques utilized, it will entice a
multi-industries collaboration to recreate the ultimate listening experience in
accordance to your room's acoustics using specified electronics.
Furthermore, for the loudspeaker created under such immense undertaking to
be appreciated continuously, the process will have to repeat itself as soon as
we move, upgrade or just change for the sake of it, unless all of us are to use
the same electronics in rooms of identical dimensions everywhere we live.
Otherwise, efforts of loudspeaker manufacturers will always be at the risk of
being misjudged, and there will never be a universally recognized candidate
for the Ultimate Loudspeaker.

With that put aside, while I don't consider the Audio Note AN-E SEC Silver to
be the perfect loudspeaker, it is a supreme embodiment of AN's "Comparison
By Contrast" philosophy, signifies a noble pursuit in the creation of a
transducer dedicated to minimum loss in signal transfer and signal to energy
conversion. As soon as the music began to play, the AN-E SEC Silver
Madrone's unassuming simplistic 2-way design became immediately
welcomed, as its incredibly complex and rich tonalities and full-range
mannerism expanded the musical horizon within the confines of my walls.

Therefore, even though the AN speakers do not have the superimposing
dimensions and looks of most world-class contenders at similar prices, the
AN-E SEC Silver Madrone's combined attributes of tonal complexity, high
efficiency, relentless resolution, the ability to relinquish high and
uncompressed decibels and its beautifully lacquered finish make it a musically
significant and wonderfully unique loudspeaker against more imposing
contenders in medium-sized rooms. The AN-E SEC Silver is a convincing
testimony to the argument that speakers reign supreme in a sound system.

As much as the AN-E SEC Silver's efficiency will accord its owner, the fun and
option of using either a solid-state powerhouse or a delicate vacuum tube
amplification, the AN speaker's resolving power endows illustrious glory to
elite amplification. These aspects of the AN-E SEC Silver ought to assure its
listener of its distinction and value among other top contenders continuously,
and is thereby such an antithesis to boredom that its owner can be repeatedly
assured of his or her investment.

Last not least, the revelatory nature of the Audio Note AN-E SEC Silver
loudspeaker mandates careful consideration by prospective owners of their
own sonic priorities and the finesse of their own systems, as the AN's resolute
nature may turn relentless if the upstream electronics impart inferiority.
Therefore, the SEC Silver must not be tackled unless you are supremely
confident of the superiority and uniformity of your own system as it will sound
adversely analytical if an inferiority potential exists.



EPILOGUE

It takes a bold, disciplined, intelligent and piercing mind to carry out Audio
Note's idealistic crusade so thoroughly, apart from a financially strong
foundation on which to sustain such operation. Also taking into account Audio
Note's impressive accomplishment in inventorying, this exhibited level of
business planning and management is a rarity in the high-end audio industry.
Being the only known high-end audio company devoted to such unique
operation on a scale so encompassing, Audio Note is not for the opportunistic
or the incongruous. Finally, Peter Qvortrup's overriding insistence in his
speakers' ability to reproduce instrument tonalities accurately reflects a
respectable and stern commitment to home music reproduction.

As musically competent as the $2,795 basic AN/E-D already is, the SEC
Silver represents not merely the fully modified and upgraded reincarnation of
it, but a thorough embodiment of the finest in a 2-way design. If the work of a
composer is an art by virtue of its enduring emotional advocacy, and the
crowning entrées of a gourmet chef constitutes an art for the elevation of one
of human's most essential endeavors, then a designer and manufacturer's
labor in creating a maximum fidelity transducer must also be considered an
artistic activity if his fruition conjures up a peerless musical experience.

If we can appreciate Junji Kimura of 47 Laboratory's concentration and
dedication at perfecting the Redbook CD playback, then we can understand
the steadfast passion of Audio Note's Peter Qvortrup in pushing the envelope
of his AN-E speaker.
