The Momentum M400 MxV Mono amplifier ($79,500/pair) is the latest iteration of Dan D'Agostino Master Audio Systems' debut amplifier of 2011, the Momentum Mono amplifier. Weighing 95lb, it is smaller and lighter than its entry-level sibling, the more powerful, 125lb Progression M550 Mono amplifier ($47,500/pair), and is veritably dwarfed by some other monoblocks, including the flagship D'Agostino Relentless Epic 1600 (570lb) and the Karan Acoustics POWERa mono (231lb), which I reviewed in May 2023. But if the M400 MxV's rock-solid look and feel and its exquisite aesthetics—a sleek amalgam of silver and copper fronted by a power meter that glows green and radiates Rolex quality—are any indication, a helluva lot is going on beneath its showy exterior.

What a show. During its four days in the MOC event center, the first two reserved for industry and press, Munich High End attracted 22,137 visitors from approximately 100 different countries. With 550 exhibitors and more than 1000 brands from 54 nations, they had plenty to hear and see.

In the extremely large, all-sonic-bets-are-off, glass-enclosed Atrium display mounted by Mansour Mamaghani's Audio Reference Munich, Dan D'Agostino, and his indispensable sidekick (aka company President) Bill McKiegan, joined forces with Wilson, dCS, and Perlisten to blow people's minds. When the new Relentless Epic and Relentless 800 mono amplifiers got fired up, it was a case of which dazzled you first, the sound or the sheer enormity and shine of the display.

Having debuted his extremely impressive Mach 8XL loudspeaker ($30,800–$33,000/pair, depending upon finish) at AXPONA, Grandinote owner/designer Massimiliano Magri and North American distributor Reinhard Goerner joined forces in Munich to preview the forthcoming dual mono, fully balanced, class-A Solo amplifier ($20,000 + options).

Twenty-five years after their founding, and 16 years after Stereophile last reviewed a Peak Consult loudspeaker, the Danish company released its new 500lb Dragon Legacy ($225,000/pair) at Munich High End. At the same time, Peak Consult, which Wilfried Ehrenholz, former audio of Dynaudio, took over in 2014, is finally beginning to reach out to the US market. After hearing the Dragon Legacy, I'm convinced that Sunil Merchant of Sunny's Components in E. Covina, CA will soon be joined by other dealers in the US.

AV RoomService's Norman Varney is committed to addressing smaller and smaller vibrations that can affect system performance ways in far less subtle than one might wish. The latest additions to his roster, shown in this admittedly less than sexy photo, includes two chassis lid damping devices. The first, a constrained layer stainless-steel damping strip that attaches internally to a chassis lid, should be affixed at an angle so that it will affect more modes. There are two models: a 12" × 2" strip ($35) or the larger 12" × 24" version ($65).
