The CEntrance AudiophileDesktop
is a new kind of audio product. It's more than a bundle.
The AudiophileDesktop brings together years of acoustics
and electronics research in one, perfectly matched system,
which raises the quality of near field listening to
a completely new level. Our breakthrough, compact audio
technology is easily transportable and delivers audiophile
sound to any desktop or bookshelf.
The unique transducer design in our
MasterClass 2504 speakers ensures wide frequency
responce and extra low phase distortion due to coplanar
driver design. The low noise and transparent sonic character
of the DACmini PX DAC/Amplifier is precisely matched
to the speakers, offering premium fidelity right at
In the words of one prominent reviewer,
the system sounds: "Detailed and accurate, yet
retains just enough warmth to appeal to those who enjoy
a less fatiguing, more forgiving approach." He
goes on to say: "The expansion and articulation
of the soundstage is immediately palpable. Tonal accuracy
and seamless control throughout the frequency range
also characterize the MasterClass speakers, a finding
wholly appropriate to a company keenly familiar with
the attributes of fine studio monitors." We couldn't
have said it better ourselves.
Each AudiophileDesktop system comes
in a road-worthy, rugged travel protection case. As
described by a reviewer: "The case is strong enough
to be shipped without any worries, and small enough
to be within specified limits for storing in the overhead
compartment, a welcome feature for those who like flying
but not leaving things to chance."
Our Audiophile Desktop product bundle packs together
a pair of "MasterClass 2504" desktop 2-way coaxial speakers
and the "DACmini PX" desktop amplifier and DAC. The bundle
also includes a travel case with custom foam cushioning as well as speaker
and USB cables.
The Audiophile Desktop system was designed from the ground
up to bring Hi-Fi sound right to the desktop for today's Internet-connected
consumer. The DAC, amp and speakers are closely matched and properly voiced
to work together in concert. The Audiophile Desktop bundle provides a
complete digital audio listening solution in an easy to carry, protective
case with custom-cut foam lining.
The new 'MasterClass 2504' near field speakers boldly
define 'mastering-quality' sound for the listener's immediate environment,
delivering audiophile sound to the desktop or the bookshelf. The unique
transducer design utilizes a patented 'coplanar' driver technology, which
eliminates interference between high and low frequencies, delivering focused
sound with precise instrument definition and wide sound stage.
Each MasterClass 2504 speaker features a full-range,
two-way 4" transducer, a carefully tuned bass-reflex cavity, a musical
cross-over circuit with custom frequency-shaping components, 50Hz...20kHz
frequency range and 25 watts of power-handling capability. The speakers
are finished in black piano lacquer to match the black anodized finish
of the DACmini PX.
The D/A Converter and Amplifier
DACmini PX is a compact DAC with built-in Class A headphone
and Class D speaker amplifier designed to perfectly complement the MasterClass
2504 speakers. It's a preamp and digital to analog converter with multiple
I/O options including: USB, optical, coax S/PDIF, analog input and output,
and a front-mounted 1/4-inch connector for professional headphones. It
features a proprietary JitterGuard jitter elimination system, and
plug-and-play driverless USB connection on Windows, Mac, Linux and iOScomputers.
Galvanically-isolated, gold-plated RCA connectors provide analog input
and output. The extended range volume control is matched to the MasterClass
speakers and also accommodates a wide array of headphones, from IEMs to
professional high-impedance models.
The DACmini PX's form-factor matches the classic Apple
"Mac mini" computer footprint, creating a perfect platform for
an audiophile-level music server on your desktop.
The bundle comes in a protective carry case designed
to secure the precious components during travel (say, you are moving to
a summer home). You can also use the case to store everything safely when
not in use. We even made sure that the case was the right size to fit
in the airplane's overhead compartment, for those who would not want to
leave things to chance.
Our Coplanar-Coaxial technology makes sure that bass
frequencies, mid range frequencies and high frequencies all originate
from the same point in space. This is not possible with traditional 2-way
speakers, where the woofer and tweeter are located some distance away
from each other. The main difference between the CEntrance driver and
the traditional speaker design is extra clarity, precision imaging and
solid soundstage, resulting from co-location of the two speaker drivers
within the same enclosure.
The innovative dual-coil driver behind the CEntrance
MasterClass 2504 speakers confines the woofer and the tweeter within
the same, shielded driver assembly. Mounting both drivers on a solid frame
allows precise alignment of the drivers' emanating planes and ensures
that all audio frequencies arriving at your ears come from the same spot
in space, not from several different places. The picture on the left shows
the driver assembly. You can see the tweeter connections at the top and
the woofer connections towards the bottom. Both moving coils use the same
magnet, a patented design. The CEntrance approach is the best possible
way of making the two drivers sound like one. The solid metal enclosure
further guarantees shielding from RF frequencies and results in clean
sound reproduction, free from unwanted interference. These speakers will
not interfere with video / TV screen technology, which is a prerequisite
for desktop reference monitoring speakers.
Custom Crossover Network
The crossover circuit is at the heart of any dual-driver
loudspeaker. It splits the audio signal into dual frequency bands that
can be separately routed to the woofer and tweeter drivers. CEntrance
developed a custom passive design to minimize phase shift, frequency non-linearity
and resulting distortion. The audio-grade caps, oxygen-free copper in
the custom-designed, core-less coil and custom low-leakage PCB make our
crossover the reason MasterClass 2504 speakers sound so good.
Bass Reflex Port
The bass reflex port is an acoustic amplifier that uses
the sound from the rear side of the diaphragm to increase the efficiency
of the speaker at low frequencies. The CEntrance MasterClass 2504
speakers feature a carefully-tuned bass port that adds a boost to the
lower end of the frequency response frequency response allowing the overall
enclosure to be made smaller without compromising bass performance. Proper
adjustment of the cabinet and port size and matching with driver characteristics
results in a smaller book-shelf speaker with audiophile performance.
CEntrance approached every little detail with highest
degree of attention. The feet on the bottom of the speakers are bolted
down, not glued, underscoring professional build quality. The feet contain
the right amount of firm, resilient foam and offer the perfect balance
of form and function. While allowing a necessary amount of cushioning,
they feature a solid grip and disconnection from the surface for better
bass. These speakers are gentle enough to not scratch your book shelf
or desktop surface yet they will not slide around during operation.
Low-Impedance Binding Posts
The CEntrance MasterClass 2504 speakers feature
gold-plated binding posts located on the back panel for easy access. Gold
plating ensures freedom from corrosion and lowers the electrical impedance
of the connection. This guarantees freedom from signal loss and stable
operation for years to come.
Our binding posts accommodate standard banana plugs as
well as cable lugs. The connectors are clearly labeled in accordance with
industry-standard practices. The positive terminal is red and is located
on the right. The negative terminal is black, located on the left.
CEntrance uses the same binding posts on the DACmini
PX DAC/Amplifier, which is voiced and tuned to work together with MasterClass
DACmini PX Power Amplifier
DACmini PX builds on where DACmini CX left off.
PX stands for "Power eXperience" it adds an integrated
power amplifier to our already popular, award-winning DAC product. DACmini
PX is really three products in one: DAC, Headphone amp and Power amp,
all packaged in a compact chassis that looks equally great on a desk or
on an equipment shelf.
The Class D power amp has 25W per channel power output.
It features our own custom design that is based on the newest technology
from Texas Instruments (CEntrance is an official 3-rd party design house
for TI, so we get access to the newest stuff first). This techonlogy features
lowest noise and super-low distortion. The digital outputs go through
two stages of extra filtering to minimize RF interference and filter out
all the grungy high-frequency components, leaving only audible frequencies
on the wire.
Perfectly Integrated, Custom-Tuned Acoustical System
Setting up an audiophile system can be a time-consuming
effort. Not only do you have to find the right components for your taste,
you also have to make sure they sound good together. And sometimes that's
difficult, because a perfectly good amp may not drive your favorite pair
of speakers, or the DAC may not sound good with the preamp. The components
may be great individually, but syngery could simply be missing.
What if someone took the time to painstakingly select
and tune the most important components for you? What if they took the
time to carefully match their critical performance characteristics? Well,
that's what CEntrance did with the AudiophileDesktop. For years,
CEntrance specialized in integrating audio technology solutions for our
corporate customers. We have integration experience and know when the
"whole is greater than the sum of its parts." Now we bring that
integration experience to you.
Digital Acoustical Synergy
This Audiophile Desktop system has "synergy"
written all over it. We created the bundle by carefully tuning the speakers,
the amplifier, the cables, the DAC and the preamp to work together in
concert. And then we went one step further. We packaged this system in
a compact, mobile travel case, so now you can take the audio quality with
you anywhere you go! Let's see how this integartion comes together.
Audiophile Desktop System is shipping with specially
designed Reserve Series Speaker Interconnect cable. These cables feature
priprietary multicore, triple-sheilded design which offers more spacious
sound, better definition, tighter bass and more openness in the highs.
The MasterClass 2504 Coplanar Coaxial Speakers
are matched up with the amplifier in several important aspects:
1) Power handling capability
The amp's output is limited right at the edge of speakers'
full power rating. It's almost impossible to clip the speakers and yet
we push them to the max, so you get maximum loudness and no distortion.
2) Frequency response
While the amplifier in the DACmini PX features a linear
frequency response and can drive most speakers, we took into consideration
the loading effects of the passive linear crossover in our MasterClass
2504 speakers in tuning the power and transient handling capability. We've
tuned the amp to the speaker's and crossover's overall impedance. Our
amp is designed to have enough damping factor to avoid the pesky mid-bass
resonance, which interferes with the frequency response.
Coaxial transducers, and especially co-incident, or as
we call them "coplanar" transducers are very revealing of non-linearities
in the audio. They feature very low phase distortion because the highs
and the lows originate at the same spot and reach your ear at the same
time. We had to invest extra money and go with a low-noise and low-distortion
amp design to take advantage of this revealing capability of our speakers.
The amp doesn't add any distortion, which one could previously get away
with because it would be masked by the speakers, but not with MasterClass
2504 sepakers. These ones reveal everything.
4) Form factor
The speakers and the amp comprise a product family that
is designed together. The system features subtle conveniences. For example,
when you position your DACmini PX on top of a speaker, the slant at the
top of the speaker's grill would allow you you to easily adjust the volume
while at the same time keeping the knobs out of the way and hard to accidentally
bump (the knobs become inset). Many more features are awaiting a chance
to thrill your senses, so go ahead and place your order today.
Cables are more than just a wire
CEntrance plays an active role in defining the leading
edge of cable technology today. Our Reserve Series Speaker Cables
are custom-designed, triple-shielded, and voiced to perfectly complement
our MasterClass 2504 Speakers and DACmini PX integrated amplifier.
These banana plug-terminated cables are a technological marvel, developed
to preserve musicality and transparency of our Digital to Analog Converters
and precise imaging of our Acoustical Transducers. These custom-designed
cables were specifically developed for the Audiophile Desktop System
and took a long time to tune just right. We are proud of the outcome.
The Audiophile Desktop System includes two 2.5M cables
(left and right).
What's in a cable?
Cables are not just pieces of wire, but rather electronic
circuits, which need to be designed right to sound right. The longer the
cable, the more important this becomes. What's at stake here are signal
loss and phase shift, both of which occur differently at different frequencies.
If left untreated, these artifacts may lead to lack of definition, loss
of imaging and reducition of clarity.
CEntrance designed its cables with the Physics of acoustical transmission
in mind. We paid careful attention to such physical properties of copper
as skin depth, flux density, dielectric capacitance, magnetic effects,
etc. Using this knowledge, CEntrance designed a custom, triple-shielded,
multi-core audio transmission system, where different copper cores
pass different frequencies, ensuring the most musical signal transmission
This level of detail in design results in sharper imaging, balanced
frequency response, no exaggeration in any one frequency band and an overall
musical tonality and balance. It took us a long time to arrive at the
magic formula for the number of conductors and the gauges of the individual
conductors. We think that the difference is very clear. Reviewers from
major audiophile magazines agree.
The Reserve Series (tm) speaker cables from CEntrance are tuned to achieve
a natural frequency balance and are a perfect companion for our DACmini(tm)
PX integrated DAC/AMP and MasterClass(tm) 2504 coaxial speakers.
