Never mind all those fancy audio components; this is all you need. Well, maybe not if you're the typical Stereophile reader or FSI attendee. This RCA console stereo (model SFA 1091) is circa-1968, and I note that it's "All Transistor." It was a part of a display of vintage audio equipment at FSI from the Emile Berliner exhibit at the Montreal Musee des Ondes.
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.
Is $140,000 the new price point for loudspeakers? No, that's not quite right—unlike the KEF Muon, the price of the GamuT S9 El Superiores is "only" $130,000/pair. Like the KEF model, this is intended to push the boundaries of what's possible in loudspeaker design, but the two speakers bear absolutely no resemblance to each other. GamuT's speakers use the principle of distributed resonance in the design of their speaker cabinets, allowing the natural resonance of each part of the cabined to decay undamped, but distributing these resonances over such a wide are that the overall frequency response remains linear, but without what designer Lars Goller's feels is the "unmusical" sound of highly damped enclosures. Here's Lars with the S9. And, yes, the speakers did sound quite wonderful.
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.
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.
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.
