Power Rating:
- ALEF Duet-SE amplifier -
Based on the extraordinary & state-of-the-art DC-6Mhz design has earned the prestigious Haute Fidelite's very rare "Reference" award!
Rated “5 stars” (highest) on ALL sonic attributes!
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."
Simply, the best sounding amplifier available… Highest level of technology Unsurpassed levels of transparency, dynamics & resolution Deeper & better controlled bass Extraordinary “Soul” that makes others sound soulless.
Nothing else compares!

Review comments
"… the sound has an impressive freedom, I am really astonished. I recognize all the nuances of my interpretation. Compliments, this has been a really interesting experience, I had never heard so well, unbelievable, impressive.” Nathalie Choquette, soprano, assisting to the Orchestra together with the Triangle Magellan Concerto at the Monaco Hi End Show on October 2010.
She said that hardly the voice of a soprano can be recorded correctly but even more difficult was to have it reproduced correctly. She came with his own master recording disc and wanted to see if really we were at the level of natural reproduction we aim to be.

Duet-SE & Director w/"Neo" ($75k) loudspeakers at Cannes ultra highend show
"The 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 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."
- Philippe Penna (Designer, Mosquito “Neo” Reference $75k loudspeaker)
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 "North Pole-SE" integrated amplifier are the perfection of actual highest technology.”
- Revue du Son Robert Lacrampe, Editor) Jan,2010
Robert Lacrampe, journalist and editor at L’Audiophile and Nouvelle revue du Son, together with his dream system. In the last issue of the Revue du Son before closing after 33 years of public service. In Jan 2010, the editors were invited to reveal what system they really would like to have in their homes, the Delta Sigma 3Mhz "North Pole" Integrated Amplifier was the heart of his dream system.
North Pole-SE
"At the recent CES2009 show in Las Vegas I spent some time in your room and came away very impressed with the Delta Sigma "North Pole-SE" integrated amplifier on display. I've heard the Manger speakers any number of times (over ten) and have never heard them sound as good as on that day. I've heard some good integrateds in the past, but that one may be the finest yet—superbly transparent sounding.”
- Martin DeWulf Editor - "Bound for Sound"
