Rave review of Essentiel in
"Stereo Prestige & Image" (May,2013)
Synthesis Of Sound Esthettique (Summary)
"The Essential compact systems are realized from excellent transducers with a very precise tuning of the filter (crossover) to get an exceptionally consistent soundstage from drivers of different technologies."
"Although it is widely considered that different technologies (ribbon tweeter for high range and conventional midbass driver) are not compatible, in the case of Essentiel, the shift between high, middle and low range is totally natural - and it's impossible to say (by ear) what type of technology is used."
"We enjoyed a precise and seamless sound throughout the range - substance from midbass to the midrange and a reference level in the top octaves. An exceptionally transparent sound including a fast, clear, precise detail of the higher frequencies without smearing, edginess or distortion."
"This results in a surprising clarity of resolution and remarkably accurate timbre (tonality)."
•Ultra-high performance drivers
•Non-resonant cabinet - reinforced in all 3-axis
•Extraordinary crossover to insure perfect phase & time coherence
•Crossover potted in resin and decoupled from cabinet
We HIGHLY recommend the NORMA 2Mhz IPA-140
Integrated as an ideal partner.

How does the advanced technology of the NORMA IPA-140
2Mhz Dual-Mono Integrated compare to others
including $85k separates?
Reviews have described the sound as world class in transparency, detail, imaging with superb dynamics & a rich, accurate tonality (voices, strings & piano sound lifelike) and fast, fast, fast!
GREAT match for High-End loudspeakers that prefer a fast & dynamic amplifier with a liquid tonality – no “dry desert” sound from digital/ice amplifiers.
"An affordable taste of state-of-the-art!"
ALEF shines at Cannes High-End show!
Comments of ALEF @ Cannes Show
from Neo ($75k) loudspeaker designer
"The (ALEF) sound is fast, vivid, dense and room-filling. Both the stereo imaging and the recreation of image depth are fantastic; the energy and the dynamics are remarkable. Both are very well controlled to avoid crisp sound in the mid-high frequencies and reproduce a perfect bass line: articulate, deep and powerful."
"Furthermore this (ALEF "Duet-SE" + "Director) Combo reproduces a natural timbral warmth and most important were the goose bumps that the emotional core of the music instilled in me. You don’t need to close your eyes to make a cerebral effort to recreate the sound of the original."
"Purity close to perfection!"

ALEF Duet-SE amplifier
Review Excerpts (translated)
Dynamics: "The Alef communicates tremendous energy on transients. The magnitude when listening to the bass line gives a real sense of presence in the room. The chords are clear and precise, the rhythm is accurately articulated and one feels no bass volume exaggeration meaning the ALEF is sovereign and in control of the lowest octaves."
"On drum keystrokes or on timbale impacts, we feel precisely and distinctly the emitted sound impulse of every attack followed by how each note ripples the drumskin. The dynamics of this amplifier is distributed on the audio spectrum in a very linear & balanced way with no part of the spectrum slighted or exaggerated. The Alef is incisive and powerful."
Soundstaging: "High level of precision of spatial soundstaging is a part of this Italian Dual-Mono stereo block. Although it has such extraordinary qualities of dynamics without restraints, one could not expect same high level of signal resolution and equally high level of soundstaging. It can virtually create a space of holographic illusion and the Alef creates a portrayal of live singing and melodic reproduction"
Tonality/Transparency: “This amplifier offers a very pure listening, very neutral listening experience due in part to the ultrawide bandwidth – on paper and also subjectively. Very powerful male voice & delicate female voice often suggest that of a triode - sometimes approaching the absolute very best with accurate voice without paralysis.”
Conclusion: "Wonderful exercise of style this amplifier Alef Duet SE (by Delta Sigma). Starting from a proprietary circuitry that can be tuned, if necessary to the need and wishes of each owner, the manufacturer propose a device capable to satisfy all situations, offering a clear, precise and defined reproduction from the extreme bass to the extreme high."
"The amplifier is able to play loud, very loud, without any audible sign of stress, or to distil a delicate melody at low volume, in class A. It can do almost everything, and does it well. The price is relatively high, but it benefits of custom, handmade manufacturing and of “sur mesure” concept - unique in the world."

"Wonderful exercise of style this amplifier ALEF Duet SE.
"Specifically when listening to changes Goldberg played in the recording the 1981 by Glenn Gould, piano on all its nuances is amazing, the sound quality is exceptional sound without added colors - top octaves effortlessly superior spectrum precision frequency and soft
fluidity; each note is separated with surgical precision and sewn in a sound harmonious and well balanced & precisely
placed in the environment."
The tone appears very neutral and with a range mediobassa
rather that shuns away from dry, hot tonal shades.
The detail remains high
over the entire range and the acoustic scene, being generally rebuilt in a credible way, helps create a sense of realism. I left intentionally for latest annotations the behavior works to high dynamics, to give further
highlighting to a performance that proved to be truly excellent.

Delta Sigma "North Pole-SE"
"At my feet, the Italian integrated amplifier "North Pole-SE" from Delta Sigma. The listening session I could share with Romain on B&W Diamond Signature and ProAC D28, all linked with cable 47 Lab, have demonstrated the extraordinary capability in current of this integrated amplifier. These two loudspeakers have been literally transformed by the energy perfectly controlled, with a strong sense of detail and subtlety…”
"These systems represent two approaches very closed to the unachievable sound perfection: the B&W Diamond Signature fed by the Delta Sigma integrated amplifier are the perfection of actual highest technology.”
