    Commençons donc par le meilleur, le constructeur chinois ESD Acoustic LLC.
    C’est la seconde fois que nous les voyons à Munich. Basée à Hangzhou, cette société récemment fondée en 2017 propose des systèmes complets aux prix peu démocratiques puisque, des deux systèmes présentés sur le salon, le plus abordable est commercialisé aux alentours de 450.000 €.
    C’est excessivement cher et en même temps certains stands du MOC regroupaient pour encore plus cher de matériel, sans que cela fonctionne aussi bien.
    Le gros système à pavillons sphériques en fibre de carbone permettait quant à lui une écoute en champ direct, donc partiellement libérée de tout impact négatif du local d’écoute, et cela s’entend. ESD Acoustic estime qu’en moyenne, leur système proposé une écoute à 85% en champ direct, ce qui permet en outre d’avoir un sweet spot très large et confortable.
    C’est le système que j’ai pu entendre à Munich depuis ces dernières années qui m’a semblé s’approcher le plus d’une écoute de concert acoustique, et ce que ce soit sur une sonate ou une symphonie. On est vraiment très proche de la perfection, et des prestations comme celles d’AvantGarde, de Vox Olympian, ou de Kondo passent vraiment pour caricaturales en comparaison.
    Le gros système s’approche des 600.000 €, même pas la moitié du prix de la Bugatti Chiron...
    Les amplificateurs classe A sont logés dans des caisses utilisant des joints à tenons et mortaises, permettant de réduire considérablement toute perturbation d'origine vibratoire.
    Le second système est un peu moins impressionnant mais reste à mon avis au dessus de tout ce que pouvait proposer la concurrence...
    Reste à pouvoir loger tout ce dispositif dans une pièce d’écoute. Celles de Munich n’étaient pas particulièrement grandes, donc j’estime que, dès lors qu’on dispose du budget pour investir dans un tel système, on doit sans doute arriver à le loger dans une pièce appropriée...

    I found this on LHF

    Great,i found this http://www.audioheritage.org/html/ou...htm#augspurger
    Dr. Bruce Edgar is the leading authority in horn loudspeaker designs for home use. Dr. Edgar's career was originally focused in the aerospace industry. However, approximately 20 years ago, he began a fascination with horn loudspeakers as an avocation. This avocation has subsequently become his vocation with the establishment of Edgarhorn to manufacture his vision of the state-of-the-art in horn speakers. Dr. Edgar has subsequently published numerous technical papers and articles on the subject of horn speakers.
    Dr. Edgar became involved with our website due to his acquaintance with Steve Schell. When Dr. Edgar heard of our website plans, he immediately offered Steve access to his files. Over the past 20 years, Dr. Edgar has developed a very considerable archive of articles and historical documents related to the history of horn speakers. Many of these documents are the only copies in existence. Some of the rare examples included the first catalog ever developed by JBL and original spec sheets from Lansing Manufacturing. These documents had been long lost to JBL.
    Dr. Edgar offered an invitation for Steve and myself to visit his facility in Torrance CA. Dr. Edgar initially gave us a remarkable demonstration of his Titan system (illustrated in above photo). This is the first horn system that I have encountered to exhibit absolutely zero coloration. It is a very impressive sounding system. Next, Dr. Edgar gave us a comprehensive tour of his shop. The photo to the right illustrates Dr. Edgar giving me a lesson in curving panels for horn flares.
    The last hour of the visit was an opportunity to just sit back and gain further insight into his remarkable career and design philosophy. Dr Edgar is the leading proponent of Tractix expansion horns. This technology was first developed by Paul Voight in 1926 but never found widespread adoption. Dr. Edgar recognized the significance of this design and subsequently refined its application. His work has led to a resurgence in speaker designs based on this concept and a resurgence in horn speakers in general.

    I"ve know Sam for many years. Hes been to my shop when ever he is in town. A true low profile audio guru.
