According to the results of a new study by the
Consumer Electronics Association (CEA), DVD players have not only achieved remarkable sales levels in the four years since their
introduction, earning the title of " fastest selling consumer electronics product of all time", but may already have penetrated into as much as one-third of all U.S. households. Additionally, the "DVD Ownership and Market Potential" survey finds that interest in owning DVD technology is staggeringly high among current non-owners. Nearly three quarters of those without a DVD player (73 percent) state an interest in purchasing one, and almost half of non-owners (46 percent) say they plan to do so within the next year. The study finds that currently more than two-thirds of owners feel that all or most of some form of DVD technology is present in one-third of all U.S. households. Among the formats included are stand-alone DVD players, DVD-enabled game consoles, and/or PC-based DVD-ROM
drives. The largest contributing factor in the rapid adoption of DVD appears to be word-of-mouth recommendations from satisfied current owners. The survey finds that an amazing 94 percent of DVD owners are satisfied with their player and are telling others. In fact, family and friends were second only to product displays in stores as an information resource used when making a DVD purchase decision. Previous research showed that concern over a lack of available software titles was an impediment to adoption of DVD technology but that this appears to no longer be a problem.
new VCC-5 Reference Center ($1,995) is the company's statement center channel speaker and was developed for use with the Model Five, 3A Signature and Reference Monitor speakers. The VCC- 5 is a three-way design based on the VCC- 1 Signature, but with the addition of two 6.5-inch cast-basket woofers. These woofers are internally mounted and cross over at 150Hz to the coaxial system, which has a crossover frequency of 3500Hz. A true triaxial output is achieved by channeling bass around the midrange-tweeter coaxial array. This is said to eliminate the severe comb filter lobing produced by horizontally displaced drivers.
International, known for its loudspeaker using bending wave driver technology, has entered the AC power conditioner market with Pion Audio
Electronics, a line of two "power cleaners" and one power cord. The Pion N3ZF power cord utilizes conductors with a 3 square-millimeter cross-sectional area for unhampered current delivery. A special conductor geometry with added damping compounds is said to eliminate current-induced conductor movements within the cable, which can create additional and cable-specific high-frequency noise. The Pion C250D power cleaner is a single power conditioner module derived from the firm's 8-channel power conditioner. The „digital“ module is particularly designed for high frequency filtering, starting in the audible frequency range and extending into the Megahertz spectrum. Power handling capacity is limited to about 250 Watts and optimized for low power source components like CD players, D/A converters and preamplifiers. The „analog“ module Pion C1200 is designed for high power gear and can handle loads of up to 1200 Watts. A very low-resistance-circuit is optimized for dynamic performance. Filtering in both conditioners is bi-directional and works from the powerline to the component and back from the component to the powersupply system.

MAP, the modular audio/video platform of Muse Electronics, has announced the release of its second generation Thalia. Based on a 4-slot modular chassis, some of the new refinements include a dual laser OPU to support recordable formats like CD-R, CD-R/W and DVD-R; 24-bit MP3 to make the Thalia the first high performance oversampling MP3 decoder; the machined Remote-1; the Sage FLI2200 high performance video deintelacer with 64Mbit memory; an enhanced menu bar and new user interface to expand upon the Thalia's usability; and an attenuator option for those who want to simplify their system.
The Creek Audio CD43 mk2 is said to be a totally new player based on the chassis size and cosmetic design of the 43 series
range. It now matches the look of the T43 tuner and 4330 amplifier. Inside a 2mm thick alloy case, the
CD-R/CD-RW compatible Creek runs a Philips transport with CD7 chipset. A high grade grain-oriented steel mains transformer feeds low impedance capacitors and separate stabilized power supplies for digital and analogue sections to "provide the highest degree of isolation and lowest noise performance possible." A custom Creek microcontroller operates a backlit green LCD display, while Crystal Semiconductor 1-bit Delta Sigma 24-bit CS4390s handle D/A conversion. A new customized low jitter master clock circuit and extra circuitry are said to minimize jitter. A re-clocked, low jitter, co-axial digital output is standard, as is a modest sized full feature RC5 type remote control handset.
Claimed to be the highest performance system in
Snell's 25 year history, the Snell XA Reference Towers were designed as a cost-no-object speaker
system. A constrained dual-layer wood/high-loss polymer cabinet (triple layer for the baffle) minimizes cabinet colorations while five 2-octave +/- 2dB frequency contour controls allow the fine-tuning of different frequency ranges and rear tweeter energy. Three bass port tuning options can alter the system's tuning frequency or convert to sealed box operation.. Snell's eXpanding Array (XA) design is said to configure their line-source such that the effective length of the array grows longer in proportion to radiated wavelength. This is claimed to give a constant vertical directivity for a very wide sweet spot with virtually no change in frequency response or perceived balance. The midrange-tweeter-midrange module is mounted to a computer-cut aluminum plate and adds a wide-angle wave guide for the tweeter. The driver complement of the XA Reference consists of 2 x 1-inch titanium dome tweeters (one front, one rear), 2 x 4.5-inch midranges with magnesium baskets and 4 x 8-inch black-anodized, long-excursion aluminum woofers. Claimed frequency response is 27 to 24,000 Hz
(+/- 3dB), with a nominal 4-ohm impedance, 87dB sensitivity and 200 watts recommended minimum amplifier power. Each speaker weighs 210 lbs and measures 72.75"
x 17.75" x 21.5" (HxWxD). Standard finish is hand-sanded, hand-painted Black Oak veneer. All other veneers and finishes carry an upcharge.
The conrad-johnson design MF-2250, 2500 and 5600 are solid-state amplifiers with a low-impedance FET-based voltage gain stage, bipolar output stage and "less than 1/1000th the feedback of conventional
designs". Audio circuit capacitors are polystyrene with less than 1/200th the transient blurring dielectric absorption of electrolytic capacitors. All resistors are low noise, precision metal foil and metal film types. The Model MF2250 offers 2 x 120 watts per channel from 20 Hz to 20kHz at no more than 1% THD or IMD, both channels driven into 8 ohm. The model MF2500 doubles this power output while the multi-channel MF5600 offers 120 watts for five channels. Dimensions and weights are, respectively, 16D x 19W x 4.25H inches and 36 lbs, 16D x 19W x 6.75H inches and 55 lbs., and 16D x 19W x 8H inches and 59 lbs.

Universal Music Group
is planning on
offering new releases of recordings by reggae legend Bob Marley. These recordings stem from Marley's multi-track live
performances between 1973-78 that have been in Universal's vaults for many years. Jeff Glixman, Director of Studio Operations for Universal Music said "It is my understanding that Universal plans to turn these recordings into releases over the next year. We are also re-mastering and releasing other classic Marley albums; there are plans for up to 15 Marley releases over the next year. Video footage of these concerts also exists, so there is the potential for DVD releases or DVD-Audio discs as well as regular CDs."
of England has launched two new loudspeaker models, the Vito and Ultimatum MF 9
towers. The Vito is a triple-cavity, 2.5 way, isobarically loaded bass reflex floorstander of 8-ohm impedance and 89dB sensitivity. The Vito is available in Cherry Ash, Rose Ash, Natural Ash, Black Ash. The Ultimatum MF9 loudspeaker incorporates seven discrete internal cavities and a multi-driver enclosure constructed from Birch Plywood. The top and front driver mount baffles are decoupled from the cabinet via a polyethylene membrane. The total baffle is a 45mm thick 'sandwich' of Birch Plywood, Polyethylene and MDF. The Ultimatum MF9 is a 2.5 way design that employs six of Neat's 168mm main drivers, a Focal inverted titanium-dome tweeter and two super-tweeters. Five of the drive units face forward in an extended D'Appolito array, with the top and bottom units handling low-bass, the inner pair bass and midrange while the main tweeter is augmented by two upward-firing EMIT super tweeters. Two separate compound chambers are employed for the low-bass sections. Finishes for the Ultimate are made to order.
new omni-polar flagship model is called the OM-1 ($25,000 - $29,000), a 4-piece system consisting of two 74" tall panels and two powered
subwoofers. Each subwoofer holds four individually powered and servo-controlled woofers in a bipolar configuration (two per side), with a 375watt amplifier per woofer or a total of 1500 watts per channel. The carbon fiber woofers employ dual voice-coil/magnet/spider assemblies so that each cone is essentially driven by two motor structures. The subwoofers are flat down to a claimed 16 Hz where the multiple patent-pending servo-control system reduces harmonic distortion to 1%. The panels themselves house eight individually enclosed proprietary drivers split between the front and rear of the panel. Dual voice-coil carbon mid/bass drivers reproduce the 80-550 Hz frequency range, where they cross over to 2" titanium domed drivers which hand over to the 1" titanium domed tweeters at 2.5 kHz. Efficiency of the panels is over 90dB, with an amplifier-friendly impedance curve that doesn't dip below 5 ohms. The OM-1’s subwoofer will also be available for separate purchase.
Muzak, yes the folks who bring "elevator music" to
over 100,000 business' has hired Stephen Villa as their new Chief Operating Officer (COO). Still, we can not help but wonder if they will now provide
real music by real bands and not the usual "happy fluffy cloud 'nother wonderful
Prozac day" music to over 100 million people daily. We can only hope Mr. Villa is a fan of
musicians like BB King, King Crimson and
Frank Zappa. Some Funkadelic and Rage Against the Machine would be a welcome change.

Audio, the consumer electronics brand sold exclusively via the Internet, has launched its ICBM Integrated Controlled Bass Manager ($249), to make up for a specific shortcoming of most DVD-Audio and SACD players. While those DVD-Audio and SACD deliver up to six channels of "full range" audio signals. they don't provide a means to extract the bass data from these channels to feed the subwoofer of a 5.1-channel system. Thus, the small 5.1 satellites must absorb this excess bass energy, which can cause significant distortion. The Outlaw Audio ICBM is a completely analog design that provides comprehensive bass management system for these players. While primarily intended for DVD-Audio and SACD, the ICBM is also useful as a high quality alternative to the less-comprehensive digital bass management included with home theater receivers and even some expensive preamp/processors.
The one-rack-unit ICBM allows individual adjustment of the bass re-direction cross-over point for each channel and channel pair in a home theater system. With the ICBM, the front left/right, front center, surround left/right and rear center speakers may be individually set to roll-off bass information at 40 Hz, 60 Hz, 80 Hz, 100 Hz, or 120 Hz, or to bypass bass management when it is not needed. The ICBM can create mono or stereo bass signals, sum the bass from each side of the soundstage to an individual subwoofer output, feed dual subwoofers and allows bass data to be sent to both full-range front speakers and a subwoofer. An LFE contour allows up to 10dB of bass boost while a rear panel switch selects between 12 db or 24 db per-octave slope.
has added the 641-SE tower speaker ($1,875) to their Signature Series loudspeaker
line. Available in more than 30 real hardwood veneers, this new model incorporates two 6.5-inch side-firing aluminum woofers
for accurate lower frequency reproduction. A high quality 4-inch aluminum
midrange and 1-inch silk-dome tweeter reproduce the upper frequencies. A slim, compact
tower design lowers cabinet reflections to improve the imaging capabilities.

Tripath Technology Inc.,
creators of Digital Power Processing (DPP®) technology, received their 11th U.S. patent (number 6,281,747, with another 59 patents pending worldwide approval) for a Power Efficient Line Driver technology used in its TLD401X ADSL line driver
products. The Power Efficient Line Driver patent covers an improved amplifier topology, which may be used to reduce distortion, heat dissipation and power consumption of virtually any type of amplifier including class A, AB, C, D, E, F, G and H. In High-End audio, Tripath technology has been implemented in Bel Canto Design's eVo line of digital power amps. In consumer audio, Tripath technology can be found in audio and video products by Sony, Sanyo, Hitachi, Alpine and Aiwa. This ongoing adoption of DPP technology by different mainstream consumer electronics manufacturers (as well as parallel developments at Sharp with their one-bit amplifier technology that operates at SACD's sample rate) suggest that cost- and energy-effective space-saving digital amplifier topologies may be the way of the future for audio amplification.
Internet audio is heating up as the mp3.com website is now pushing the new
mp3PRO format while the Internet Streaming Media Alliance has released ISMA 1.0 of the MPEG-4 audio/video
protocol. mp3PRO compresses audio twice as efficiently as standard mp3, yet is also backwards compatible. The Frauenhofer Institute of Germany mp3PRO format employs more advanced psychoacoustics techniques and also "...splits audio recordings into two parts. One part analyzes the low frequency band information and encodes it into a normal mp3 stream. This allows the encoder to concentrate on less information and allows it to do a better job of encoding. This also maintains complete compatibility on old mp3 players. The second part analyzes the high frequency band information and encodes it into a part of the mp3 stream that is normally ignored by old mp3 decoders. New or upgraded mp3PRO decoders will tap into this part of the stream and put the two bands back together, resulting in the full audio bandwidth."
The Internet Streaming Media Alliance
(IMSA) has now published their specifications for streaming MPEG-4 video and audio for Internet protocol networks. "As a first in the streaming media industry, ISMA 1.0 will allow content creators, owners, distributors and aggregators to be able to choose products and solutions from different vendors, and thus tailor their systems purchases to their exact needs," said Hans-Peter Baumeister, board member of the ISMA. "In addition, and also as a first in this industry, we can expect to see a truly competitive marketplace for streaming components and solutions, assuring continued improvements and innovation in this space." The ISMA was formed only a year ago by founders Apple Computer, Cisco Systems, Kasenna, Royal in hopes of having a set of standards within the industry.

is entering the power conditioner arena with its new Reference Series of Balanced Power and AC Regulator
units. The first product in this line is the Model IT-Reference ($3000) that's claimed to offer more than 24dB of AC-line noise attenuation and 80dB of RF noise rejection with four individually isolated, electrostatically shielded, symmetrical power banks for equipment with low to intermediate power needs. High power components, such as power amplifiers and powered subwoofers, are supplied separately via a high current bank, providing ultra-low impedance, filtered, non-symmetrical AC. Symmetrical (balanced) power operates at +60 and -60 VAC (rather than +120 VAC and neutral) to cancel common-mode line noise. Highest industrial quality "super-spec" isolated-ground outlets used throughout, and all symmetrical power banks are individually ground-fault (GFCI) protected. A power correction circuit provides protection from equipment-damaging spikes and surges via a precision high inrush magnetic circuit breaker. The IT-Reference is claimed to provide in excess of 8 Amps of current "headroom" for the most extreme peak power demands.

the professional division of TEAC, calls its CD-RW2000
($1125) "the most advanced stand-alone CD recorder available." It includes XLR/RCA balanced/unbalanced I/O, word sync input, call function for checking play cues, digital gain adjustment and digital fade in and fade out. A RAM buffer ensures tight ID markers without danger of clipping the start of the track, and the SCMS code can be set via the user menu. Digital gain adjustment allows signal boost without going back to the analog source, and the adjustable auto cue function localizes the start of actual audio rather than track ID. The CD-RW2000 plays and records on both 74min and 80min CDs and SCMS copy protection is selectable. A wired remote is included.
