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 (5701b) and the Karan Acoustics POWERa mono (231lb), which I reviewed last month. 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.
Once I took a listen, I discovered sound so smooth and satisfying that the refrain "How ya gonna keep 'em down on the farm / After they've seen Paree," from a WWIera song about soldiers not wanting to return to their family farms after experiencing big city life in Paris, kept playing on repeat in my head.
Direct from Cave Creek
What kind of amplifier is this that distracted me so from watering the cows and milking the chickens? D'Agostino's website² offered a few clues. The Momentum M400 MxV is hand built; it includes discrete, direct-coupled, balanced circuitry and boasts a "new, ultra-quiet 2200VA linear transformer" with a winding scheme that is said to reduce the hysteresis effect by 90%, minimizing power and thermal loss. The new winding method also plays a role in increasing current capability by more than 50% and "offer[ing] greater headroom during dynamic passages," which is surely aided by a bank of nearly 100,000μF of supply capacitance. All that adds up to potential output power of 400, 800, and 1600W into speaker loads of 8, 4, and 2 ohms, respectively.

Audia Flight FLS10
The dogma of separates has long reigned supreme among audiophiles: If you're serious about sound quality, you're supposed to need a dedicated preamp and power amp.
Totem Acoustic Element Fire V2
Totem Acoustic was founded in 1987, in Montreal, Canada, by a former high school math teacher named Vince Bruzzese. The company's first product, the Model 1 loudspeaker,' impressed me so much I bought a pair.

The Spin Doctor checks out the Kuzma Safir 9, a superarm from Slovenia.
The British audio scene from the late 1970s through the mid-1980s was pretty strange. Audio as a hobby was a big deal, with widespread appeal to a much younger crowd than today. Audiophiles were guided by a flurry of what my friends called \"hi-fi pornos,\" audio magazines that filled the racks at the newsagents.
Alex goes to Japan
Arriving in Japan from the United States is like being turned upside down. This condition lasts for much of the first week. When I visited in November, the time difference between Tokyo and New York was 14 hours. \"The floating world\" is a term for the pleasure-addled urban culture of Edo-period Japan, but it's also an apt description for the twilit and not-entirely-unpleasant weirdness of first arriving in Tokyo. Everything seems slightly unreal.
