The WCS-2 record cleaning machine ($750) was only one of the many worthy and provocative things happening in the Music Hall room at the Venetian. We say provocative because WCS stands for wet clean suck—don't blame us, we're just reporting—and partly because Roy Hall treated us to a monologue about how "I've always told my customers to go **** themselves and I've been successful beyond my wildest dreams." Also shown were prototypes of the forthcoming Ikura turntable which combines a plastic dual plinth with a carbon fiber tonearm and will sell in two versions, one with MDF platter for "$1000-ish," and a step-up model with acrylic platter and different cartridge. But the most provocative thing was the sheer quality of the sound that emerged from a system combining the Music Hall-branded Marimba speakers ($350/pair) and stands ($250/pair), a70.2 integrated amp ($1499 with phono stage), and USB-1 turntable (a mere $250 including Ortofon cartridge). A highly natural vocal treatment combined with a mighty synth bass to produce what was quite simply one of the best audio demos at the show from a system cost that's less than what some audiophiles would spend on cables.

Tivoli's wildly successful Model One and PAL radios now come in Bluetooth versions. Adding the wireless capability pushes the price of a Model One from $149 to $259. Also touted was the free Tivoli Radio app, which offers iOS and Android access to 100 of the internet radio stations that Tivoli's servers supply to the NetWorks internet radio.

The Scandinavian speaker maker DLS started as a car audio company in 1979, moved into home audio in 2003, and released its first on-walls in 2008—and they are now a big part of its business. The Flat Box II is the large speaker on either side of the picture. Under the grille are an active woofer and passive radiator, made of Kevlar and aluminum, flanking a silk dome tweeter whose wave guide extends from the baffle to the grille, as a means of tightening up time alignment. It goes for $3500/pair. In the middle of the pic is a forthcoming full-range speaker which will be more design-oriented and will sell for $2000/pair. DLS also offers numerous other on-wall models combining 1.5-inch soft domes and three- to four-inch paper woofers, chosen for their efficiency with minimal amplification, selling for $500-1000/pair.

Gallo is overhauling its acclaimed lines of orb-shaped metal-clad satellite speakers with the new A'Diva and Micro lines, which are five and four inches in diameter, and sell for $329 and $239 each. Both use a new full-range driver that is said to offer wider dispersion, though at the cost of a slight reduction in efficiency. Don't worry, an average receiver should be able to run them fine.
