The Galactus-sized Audio Research Reference 610T monoblock amplifiers ($20,000/ea) put out 600W. They require 8 matched pairs of 6550C output tubes, one 6550c regulator, one 6H30 as an amplifier regulator, a pair of 6550Cs as drivers, two 6NIP input tubes, and a 6H30 follower—that's a ton of tubes.
Kevin Wolff, Vienna Acoustics' new international sales manager, poses next to the new $25,000/pair The Music loudspeakers.That rotating section of the cabinet contains Vienna Acoustics' revolutionary (hah!) new, flat, concentric 7" tweeter-midrange unit, which handles frequencies from 200Hz to 20kHz. A separate super-tweeter takes over above the audioband.
A closer look at Vienna Acoustics' coaxial tweeter-midrange unit. The central dome is supported by the magnet pole-piece of the flat midrange driver—and the strengthening ribs are said to dissipate standing waves on the surface of the driver.
Mutine's Pascal Ravach was demonstrating the small, but striking, Duevel Planets omnidirectional speakers (CDN$1495/pair), The Planets consist of a floorstanding vented cabinet with an upward-firing 5" woofer and 1" horn-loaded tweeter. The drivers fire against reflective spheres, which disperse the sound.
