The talk of the show was Dan D’Agostino’s first product since forming his new, eponymous brand.

Rated at 300W into 8 ohms, the Momentum monoblock weighs 95 pounds, thanks to solid-copper heatsinks running along the sides of the 4"H x 12"W x 17 3/4"D chassis. The tentative price is $42,000 per pair.
