The Wavemaster monoblock power amplifiers ($9000–$10,000/pair) can put out 200W into 4 ohms. They employ an Audience discrete-component front end, switching power supply, and come with an Audience Power Chord. They accommodate single-ended and balanced inputs.
The speakers from Colorado-based Avalon Acoustics have either featured conventional, rectangular boxes (in the less-expensive NP series, like the Evolution 2.0 I <A HREF="http://www.stereophile.com/floorloudspeakers/708ava/">reviewed last July</A>) or the unique, multifaceted enclosures that I first saw in 1990's <A HREF="http://www.stereophile.com/floorloudspeakers/703/">Eclipse</A>, which are used in the cost-no-object designs like the <A HREF="http://www.stereophile.com/floorloudspeakers/1008ava/">Indra</A>.
Taking pride of place in distributor Sumiko's suite on the Venetian's 35th floor were the new Vienna Acoustics Kiss loudspeaker ($15,000/pair). Part of the company's Klimt series, the Kiss is ostensibly a stand-mounted design, but the side-pillared, faintly convex stand is part of the design concept. One drive-unit—the flat, radially ribbed unit first seen in the Vienna Musik, covers the entire range of the human voice, 120Hz–2.6kHz, and is married to a tweeter in its center and a port-loaded woofer. The latter features the ribbed, transparent polymer cone material used in Vienna's line, but has a multiple-radius cone profile to maximize stiffness and minimize mass.
Demonstrating the obsessive attention to detail in Vienna Acoustics' new Kiss loudspeaker are the micrometer-realized alignment adjustments on its rear panel.
"It's like the Pearl but in a more easily digestible form," explained Jeff Joseph, as he demmed the Long Island's company's new Pulsar speaker for me. The stand-mounted speaker keeps as much as possible of the cost-no-object Pearl's qualities, but uses a new magnesium-cone woofer from SEAS with the same throw as the Pearl's 7" unit.
While bunches 'o companies were hopping on the USB DAC bandwagon, Weiss quietly goes their own way, focusing on getting the audio out of your computer via FireWire. The company also sells professional audio equipment.
The omnidirectional MBL speakers, which use a unique pulsating quasi-spherical array of ribbons, make a strong argument for the benefits of this design approach. Featured in their room when I visited was the new 111F ($35,000/pair), which uses the "Radialstrahler" drivers for the treble and upper midrange, with conventional drive-units used for the lower frequencies. A big change from the earlier version I <A HREF="http://www.stereophile.com/loudspeakerreviews/643">reviewed in 2002</A> was the use of side-firing direct radiators for the bass rather than the 111B's coupled-cavity LF enclosure. These are mechanically coupled to eliminate vibrational excitation of the enclosure.
Here's the phono transformer that completes the Ypsilon phono section—for them what needs it (price tbd).
Here's an inside look at Ypsilon's forthcoming phono section (price tbd). Clean layout, no?
