Audio Analogue Crescendo Integrated Amplifier
The Crescendo Integrated Amplifier is an appliance which can deliver 50W on a 8Ohm load with a THD+N of less then 0.05% and 80W on
a 4Ohm load with a THD+N of less then 0.05%. So the ratio of the 8Ohm and 4Ohm power is extremely good, if not absolutely astonishing for
an item in this price range! What’s more, the additional characteristics of the unit not only make it a real benchmark in its class but a whole
lot more because it is, in reality, a “true high end” integrated amplifier! The SNR is more than 100dB and the band-width more than 150KHz.
We haven’t just tried to reach good electrical stats, but, in line with the Audio Analogue philosophy, we have also worked attentively on the sound,
which has been perfectly tuned to the Crescendo CD Player.
The Crescendo Integrated Amplifier has also been designed to be really very versatile:
• It has 5 Line Inputs and a frontal input to be connected to a MP3 Player Line Output, such as an iPod, it also has a REC Out and a Phone Out.
• The LINE Input 5 can be configured in By-Pass mode to easily place the Crescendo INTEGRATED AMPLIFIER in an audio video system (Click Here for details),
in such a configuration the Crescendo INTEGRATED AMPLIFIER can drive the front loudspeaker, which can easily be shared between the Stereo-System and the
Audio/Video-System increasing also the overall Audio/Video audio quality.
• The possibility to choose the volume scale steps to match the steps to the loudspeakers’ sensibility (Click Here for details). 4 different scales are available,
3 of which have been designed for different loudspeaker sensitivity and the last with 79 steps, 1dB each, for the most precise scale of all, if required.
• The balance function.
• Crescendo IA has a Trigger-In input by which it can be switched on by the Crescendo CD Player or by the Crescendo Tuner/USBDAC.
Audio Analogue Verdi Settanta REV2.0
The Verdi Settanta REV2.0 Integrated Amplifier represents an accomplished expression of Audio Analogue’s new strategy aimed at giving users
the best quality yet taking into the due account their budget. Every operative feature and performance of the Verdi Settanta is optimized to
maximize the customer’s satisfaction, sound quality, manufacturing and assembly perfection, look & style and performances, together with
the famous family look and ease of use common to all Audio Analogue products. The user perceives a very high class: great contents, superb
sound and long-lasting with no wearouts or performance detriment. The new, totally remote-controlled hybrid circuit delivers crystal-clear
power up to 70W per channel on 8 Ohm, with dynamic headroom sufficient to satisfy the requirements of every speaker in the same price
range and beyond. Tha power stage is made around the now usual LM3886T power packs (same as those used on the famous Jeff Rowland
amplifier, Concentra): they are BJT integrated power devices able to deliver currents up to 12A and perfectly protected agains overloads and overheat.
The “smart” protections used in these deviced allow for, in normal operation conditions, the deliver of huge power without limiting the dynamics of the output signal.
The hybrid preamplifier circuit is made using a 6922 double triode per channel as gain stage and balancer, to drive the power stage in balanced mode.
It operates a perfect interface between the integrated bufferless resistor network potentiomenter and the power amp’s input, contributing to the balanced
yet vivid and crisp sound of the amplifier. Solid state input selectors allow for indefinite best quality performance (no sound detriment due to metallic contacts
ageing and wear-out). The MM/MC phono stage allows for the use of avery cartridge with more than 0,2mV output voltage. Few amplifiers in this price range
have this feature. The remote control also allows users to control the “companion” CD player Rossini, as well as the Primo CD player, the Primo Tuner VT
and the “companion” tuner of the Verdi SETTANTA REV2.0 when available. Of course, all the main features of the amplifiers can be used by the front panel’s
controls. Great care has been used in the passive and active components selection, as usual for Audio Analogue.
Audio Analogue Verdi Cento
We believe vacuum tube technology is, even now, very valid in treating the audio signal in a preamplifier stage while leaving to solid
state technology the task of the Power stage. So this has been our design philosophy: a vaccum tube preamplifier stage to take advantage
of the audio properties of that technology and a solid state power stage as much “transparent” as possible.
Other important innovations concern the settable Mono / Pre Out and added use functionalities.
Audio Analogue Puccini Settanta REV2.0
The new, totally remote-controlled discrete components circuit deliver crystal-clear power up to 70W per channel on 8 Ohm, with
impressive dynamic headroom. Very accurate protections save the power stage and the speakers from burn-outs, while allowing
for full dynamic power delivery in every normal listening situation. The high-performance discrete components preamplifier circuit
operates a perfect interface between the integrated bufferless resistor network potentiomenter and the power amp’s input, contributing
to the balanced sound of the amplifier. Solid state input selectors allow for indefinite best quality performance (no sound detriment due to metallic contacts ageing and wear-out).
The Puccini70 REV2.0 has a phono input with which both MC and MM cartridges can be used and has a MonOut output to directly drive an active subwoofer.
A special bypass feature, selectable by remote’s “setup” option, allows the user to turn the Puccini 70 REV2.0 into a power amplifier on a
specified input, to include the amplifier in a multichannel system as front speakers power amp, while using the same speakers for two
channel listening using the stereo sources connected to the amplifier.
The seven-keys solid brass remote control allows for a more flexible control of the Puccini 70 REV2.0. Of course, all the main features of
the amplifiers can be used by the front panel’s simple controls.
Great care has been used in the passive and active components selection, as usual for Audio Analogue.

quality, manufacturing and assembly perfection, look & style and performances, yet retaining the famous family look and ease of use.
The elegant yet sober appearance of the Bellini Virtual Battery REV2.0 will allow for a discrete placement in every domestic environment,
with both classic style or modern furniture.
The new, totally remote-controlled discrete components circuit deliver clean, crystal-clear with bandwidth and dynamics that meet
the requirements from the new high-resolution digital sources.
The unique off-line virtual battery supply, improved version of the one already introduced with the Aria phono preamplifier, ensures
an absolute immunity to every disturbance that could come from the mains through the power transformer’s and regulators’ parasytic capacitances.
The high-performance discrete components preamplifier circuit operates a perfect interface between the integrated bufferless resistor network
potentiomenter and the power amp’s input, contributing to the balanced sound of the amplifier. Solid state input selectors allow for indefinite
best quality performance (no sound detriment due to metallic contacts ageing and wear-out).
The special line/phono input can be set to operate as a phono MM input, phono MC, or even line. It uses the samerefined, high-dynamics
circuit as the Aria phono preamplifier and gives user the maximum flexibility to set the interface to the cartridge and the gain.
The balanced input and the quadruple outputs (two single-ended sets and two balanced sets) allow for a universal interface capability and
passive bi-amping. A 12V trigger output allows for slaveing the power amplifier or any other equipment switching to the Bellini Virtual Battery
REV2.0: all the system can be turned on and off using the preamplifier’s remote.
A special bypass feature, selectable by remote’s “setup” option, allows the user to turn the Bellini Virtual Battery REV2.0 in a straight line from
a specified input to the outputs, to include the preamplifier in a multichannel system in which the related power amplifier is used to drive the
front speakers, while using the same speakers for two channel listening using the stereo sources connected to the preamplifier.
The seven-keys solid brass remote control allows for a more flexible control of the Bellini VB. Of course, all the main features of the amplifiers
can be used by the front panel’s simple controls.
Great care has been used in the passive and active components selection, as usual for Audio Analogue.

performance, especially increasing the "speed".
Power stage: we have changed the compensation method of the stage to have a better THD + N and changed the values of some of the components to increase the speed.
The REV2.0 has a true balanced input.
The phono preamplifier has been modified and improved.
The REV2.0 has a main power supply switch.
The REV2.0 has a new very smart and reliable VFD technology display (black background and white characters).
Audio Analogue Maestro Duecento SE
INTEGRATED AMPLIFIER
The Maestro Duecento Integrated Amplifier SE comes after a four year period of diligent research that Audio Analogue has been
developing on the standard Maestro Duecento Integrated Amplifier.
The research, directed towards a perfect tuning of the unit, has concerned both the selection of the passive components (with special
attention paid to the capacitors) and several inner wiring strategies. The implemented changes in such areas have permitted the unit to reach a higher level of audio performance.
These improvements previously reserved for only a small group of audiophiles are now available to a wider public with the birth of the Maestro Duecento Integrated Amplifier SE.
Audio Analogue Class A SE
INTEGRATED AMPLIFIER

Audio Analogue Maestro Stereo line Preamplifier SE
PREAMPLIFIER
MAESTRO LINE PREAMPLIFIER SE: no envy for Perfection!
The Maestro Line Preamplifier SE has been developed based on the Maestro Line Preamplifier, completely renewing the power supply stage and
improving the preamp section after highly accurate detailed listening tests performed on the passive components. The implemented technologies
and the manic attention in choosing each passive component has elevated the sound output to absolute reference quality and has made the sound of the
Maestro Line Preamplifier SE a benchmark in the category of preamplifiers of the very highest level.
VR Power Supply (voltage reference): The power supply we have designed develops a philosophy different from that generally followed in the audio field.
In fact, the power supply is normally obtained from a secondary stage of the transformer whose voltage is rectified and then stabilized and filtered as much
as possible in order to reduce the ripple. In the Maestro Line Preamplifier SE a “traditional” power supply, such as the one previously described, has been
implemented to have a very clean voltage (as much as 3 different stabilization stages have been used for each supply!) but the voltage is not used to supply the preamplifier
section! Instead, the voltage, which is already very clean, just supplies the circuit where the proper voltage for the preamplifier circuits is generated.
The voltage to supply the preamplifier section is derived from an extremely clean and stable (both thermically and temporally) voltage reference. Such
voltage is hence treated to reach the level required for the preamplifier section. All the chain has been designed using extremely low noise strategies.
The board for example is a 4 layer one (to have a generalized bypassing of every signal) as apposed to the standard 2 layer boards commonly used in the audio field…
Pre section: the preamplifier section has been revisited changing the passive components after a series of highly accurate listening tests. In the course
of such tests many different kinds of passive components have been checked in several different positions to obtain the best sound coherence. Moreover,
in some parts of the board the lay out has been changed to emphasize some particular characteristics.
All the analogical circuits are made using discrete components, and have a large-pass band and low-feedback factor.
Only the Highest-quality passive components have been used; lowest-tolerance metallic layered resisters (MIL standard); low-tolerance, non-polarized
polyester / propylene condensers; high-speed, low-loss, high capacity electrolytic condensers; organic-electrolytes, low-capacity electrolytic condensers.
The integrated-resistance network volume controls used have no buffer for maximum sound transparency.
Audio Analogue Maestro MonoAural SE (monoblock)
POWER AMPLIFIER
The Maestro Monoaural Power Amplifier SE comes after a four year period of diligent research that Audio Analogue has been developing on the
standard Maestro Monoaural Power Amplifier.
The research, directed towards a perfect tuning of the unit, has concerned both the selection of the passive components (with special attention
paid to the capacitors) and several inner wiring strategies. The implemented changes in such areas have permitted the unit to reach a higher level of audio performance.
These improvements previously reserved for only a small group of audiophiles are now available to a wider public with the birth of the Maestro Monoaural Power Amplifier SE.
Audio Analogue Enigma Rev 2.0
MULTIFUNCTION AUDIO UNIT
Audio Analogue goes on in its research to solve the enigma:
“Is it possible to create a multifunction audio unit, what is also called an “all in one system”, with a so high sound quality to be compared to the best audiophile systems?”
With Enigma Rev2.0 the answer is yes!
The audio chain design started choosing a new Vacuum Tube Preamplifier section based on the Rossini CD Player REV2.0 output stage that
gave us surprising results. Then all the parts have been matched to the preamplifier stage. Important changes have been implemented in
every part, but especially in the power stage and DAC section. The audio quality resulting is astonishing!
The Enigma Rev2.0 has a new more essential design with a line input on the front to be connected to a line output of a MP3 Player such as the
iPod to meet the increasing interest in that kind of audio sources even in the High-End field. Also a Monout output has been added to connect a
active subwoofer and a completely very efficient new software has been implemented.
Enigma Rev.2.0 solve the enigma. It is a unique product because for sure on the market there are not “all-in-one” systems with similar audio quality.
We can absolutely assert that Enigma Rev2.0 for its sound can be well compared with even higher expensive true High-end systems.
