“…but inner illumination is what I heard on Hiroko Kokubu’s fine-sounding, ultra-refined version of “Besame mucho.” The system sounded equally fine on the fabled von Karajan recording of Beethoven’s Triple Concerto with the Russian giant triumvirate of Oistrakh, Richter, and Rostropovich….”

Jason Victor Serinus, Stereophile Axpona 2022 Show Coverage.

“…This system was utterly mesmerizing with human voices, and that low bass is even more visceral than before, which is still surprising since the Legato Duo is still slim and svelte despite its floor-standing classification. It’s an engaging, musical loudspeaker…”

Marc Phillips, PartTimeAudiophile.com

“,…The room featuring the white floorstanding Sonner speakers sounded very good to my ear with a great sense of space…”

Rick Becker, Enjoythemusic.com

“…There was excellent scaling of the seven solo instruments involved in L’histoire du soldat and these modest-sized speakers handled Power Music quite respectably, with bass response specified down to 43Hz…”

 Andrew Quint, The Absolute Sound, Axpona 2018 Show Coverage.

“…The room filled with a sweet and refined sound that never once sounded harsh or strident, even at louder volumes. The tight synergy with the pure Class A Luxman integrated amp was obvious, as the sound struck a perfect balance of dynamics, clarity, and flawless imaging…”

“…The surprising part was that during this movement, I raised my left hand to show the tempo while I gestured for different musicians to enter, rise and fall away with my right. That’s how engaging the Allegro Unum is…”

Richard Weiss, Monoandstereo.com

“…Where the Allegro Unum’s shine, is how balanced and detailed they are. Nothing is left out of the sonic picture, or left smeared in the sound-stage. The top end is not fatiguing and the presentation completely smooth and comfortable for those sometimes long and loud listening sessions.”  

Erik Franklin Shook, Parttimeaudiophile.com

“… The skill evident in the way it is balanced lets the natural warmth of music show through. The other skill set Unum brings is very fast yet critically damped rise and settling times, they start and stop on the proverbial dime. On classic Elvis and ZZ Top Americana blues rock the PRaT (pace, rhythm, and timing) is spot on. Imaging is a specialty of the time aligned Unum, regardless of the track demo’ed they throw a sound field that blossoms out filling the room. Most of our systems will on occasion image beyond the edges of our speakers, i.e. left of the left speaker and right of the right speaker. With the Sonner Allegro Unum that was the default presentation as the air and space of the venue fill the room. This was not some parlor trick or affectation. The recording’s room acoustic was just there in a space populated by the performers…”

Norman Tracy, Positive Feedback.com

“…transfixed by the full, lively and dynamic sounds coming from this simple yet elegant bookshelf speaker..”

Marc Phillips, Parttimeaudiophile.com

“… To hear the Legato Unum would have your jaw drop, and then to switch over to the Allegro Unum, would have your jaw drop again. It’s a weird place to be if I were to be totally honest…”

Erik Franklin Shook, Audiohead.com

“Finesse and grip” is the lead-off description in my listening notes The Sonner Audio Legato Unums are extremely capable speakers that highlight detail and yet still provide a smooth and soulful sound. Bass on the Sonner’s is much beefier than expected even with lower powered amplifiers. However, here at CAF, with all of this headroom at our disposal it’s as if the monitors have forgotten that they are indeed monitors.”

Erik Franklin Shook, Parttimeaudiophile.com

“…Satisfying orchestral weight and timbral nuance was evident…”  

Andrew Quint, The Absolute Sound, Axpona 2018 Show Coverage.

“…by delivering exceptional wide, deep, and well-focused sound stages that were truly impressive..”

Chris Martens, Chief Editor Hifi Plus

“…The resulting reproduction was observed to be very clean and transparent with surprising bass fullness and dynamic capabilities. Good transparency at low levels, whip-crack fast transients. Like an electrostatic with more horse power and excellent imaging. That a reasonably sized monitor can offer such dynamics and power is very impressive.”

Norman Trace, Positive Feedback.

“….Smooth and relaxing was my initial take on the system. As we moved around various tracks, the character of the Sonner Audio Legatos never strayed far away from smooth, but depending on the media, the former relaxing was often exchanged for a thrilling and exciting performance. What made the system click with me most was that it imaged wide, placed instruments tightly, and held a space open for depth in layering. Sound-stage height was also pleasantly large…. “

Erik Franklin, Parttimeaudiophile.com

“… this small room allowed for the development of a nice sense of space. It generated a deep accurate stage, with delicate inner detail on vocals and piano, and a very pleasing sense of instrumental bloom..”

Greg Weaver, Enjoythemusic.com

“…played Reference Recording’s Big Band Basie, a live recording, I could clearly hear everything going on, including the hall itself…”   

Alan Taffel, The Absolute Sound, 2018 NYAS Show Coverage.

“… has a nice, big, spatial ease coupled with delicacy and nuance. Nice.”

Michael Lavorgna, thetwitteringmachine.com

“… it was a pleasure due to the tremendous fidelity of the speakers and also the terrific choices of music and quality of these recordings… “

James Larson, Audioholics.com

” .. It released a lovely, grainless treble notes, warm mids and quite deep lower-bass notes…”

Ken Micallef, Stereophile

“…. I got a nice big soundstage, good dynamics, the Allegro’s disappeared and the searing guitar dominated. I really had a good time in this room.”
