Un artículo donde se comenta sobre el gusto que aun hay por viejas tecnologías de audio en casa que no han sido del todo eliminadas ni por el CD y mucho menos por el MP3.
Tornamesas, discos de vinil, hasta reproductores de 8 pistas aun son apreciados por muchos, que evocan no solo un sentir o un sonido sino su vida misma através del sonido que generan.
Y si esto aparece en WSJ seguramente será leído por directivos de compañias y posiblemente se generará mas aun ese efecto retro en el que vemos resurgir equipos ya pensados para estar extintos a estas alturas.
Para finalizar dejo este comentario de Dave Bales, director de productos de audio en Pioneer Electronics:
"... el audio análogo era un poco demasiado técnico..."
Pero bastante más placentero y entretenido sin duda, añadiría yo, para sesiones de escucha y no simple almacenamiento neurótico de canciones sin mas gusto que el contarlas o hacer filita en la fiesta y levantar la mano para exclamar ridículamente triunfante "yoooo si la traigo".
Más aun, este fin de semana pude escuchar un sistema con iPod, DAC Moon, preamplificador Odyssey Tempest Extreme, amplificadores Odyssey mono Extreme SE, CD para DJ Denon y bocinas B&W 803 (top) y aunque el iPod de momento suena prácticamente irreconocible, un cambio al CD me dejo redescubrir que aunque sea poco pero elementos vitales y musicales si se escuchan mejor, mas resueltos, dinámicos y extendidos en el CD.

The Wall Street Journal: Los sistemas estereo de casa que se niegan a morir.
Ruido EMI causa de problemas de Toyota y tambien para aparatos audio y video.
Un viejo conocido, Electro Magnetic Interference le ha agriado el caso a Toyota pero no es problema solo de la legendaria armadora, las otras estan en iguales o peores posibilidades y muchos de los equipos de casa por causa de este villano llamado EMI.
http://seekingalpha.com/article/187021-toyota-s-electromagnetic-interference-troubles-just-the-tip-of-the-iceberg
In the "Study to Predict the Electromagnetic Interference for a Typical House in 2010", the author, Anita Woogara at Bristol University, says:
Cars and other vehicles now contain many electronic systems. These range from electronic engine management systems to achieve maximum efficiency to electronically operated airbags to protect the driver in the event of a crash. Unfortunately this leaves cars more vulnerable to electromagnetic interference. Mobile phones and passing taxi radios have been known to interfere with Anti-skid Braking Systems (ABS) and airbags, causing drivers to lose control of the car. Car ignition has been changed recently to a short high voltage spark, although better for exhaust emissions this causes wideband interference. As the car industry is very competitive, cutbacks are often made on the wiring, which increases the risk of susceptibility.The inclusion of computers in cars for navigation purposes will also increase the susceptibility.
Automobiles are covered in the Automotive Directive; this excludes them from the EMC Directive on sub-assemblies and devices that may be sold separately from the vehicles. All of the systems in the car have to be able to work simultaneously without interference from each other; ignition interference and external radiated interference. However, interference from objects brought into the car, such as mobile phones and laptops, may have been missed out. Additionally, household electronics can be affected by cars outside, in the street or garage, which is especially relevant in houses with small front gardens.

Jensen retro...
Jensen es una de las marcas mas veteranas en la electrónica de consumo, ya pasaron sus mejores épocas sin duda y ahora son propiedad de la canadiense Audiovox. Mi papá me comentó ahorita sobre la marca y me surgió la curiosidad por ver que tienen, es obvio que no es una compoañia dedicada al Hi Fi y menso al High End pero encontré este producto JTA-380 que me llama la atención pues se ve bastante retro, por ahi de los 60's o 70's si mis apreciaciones no me fallan.Casi increíble pero cierto: 600 Watts de potencia en un chip.
Texas Instruments presentó su nueva generación de amplificadores integrados Pure Path Clase D, con una salida de 600 Watts en mono y 300W en estéreo.
Texas Instruments Inc. announces the TAS5630 and TAS5631 Class-D audio amplifiers that advance the home entertainment experience. The devices are capable of driving 600W, featuring the highest stereo output power in the industry that is more than twice that of the closest comparable devices.
Using TI's closed-loop architecture, the amplifiers integrate PurePath HD technology to achieve HD media playback and ultralow distortion in A/V and DVD receivers, Blu-ray home theater systems, home theater-in-a-box, mini/micro component systems and professional audio systems.
The devices feature audio bandwidth exceeding 73kHz to achieve high-definition media playback in applications such as in Blu-ray home theater systems. They offer low distortion across frequency, delivering a rich, natural sound. Plus high power supply noise rejection reduces BOM and lowers system cost by relaxing power supply requirements.
Also, the audio amplifiers offer 300W stereo or 600W mono output power at greater than 88 percent efficiency, eliminating the need for transformers or large heat sinks, reducing BOM and total solution cost. A 0.03 percent THD at 1W into 4Ω load (stereo) provides ultra-low distortion at normal listening levels. Thus the devices offer power levels equivalent to traditional discrete Class-D amplifiers with 70 percent fewer components, lowering system failure rate, accelerating time-to-market and achieving higher manufacturing yield.
Power supply reference designs are available to further simplify development, and design is made easier by analog and pulse-width modulation (PWM) input options in pin-compatible packages that maximize design flexibility. Specifically, pin compatibility with the TAS5615 and TAS5616 150W stereo amplifiers maximizes design reuse for lower power systems.

New HDTVs May Soon Be Obsolete? Thanks a Lot, 3D
Just bought a new flat-panel HDTV for Christmas? Enjoying that new Blu-ray disc player? Guess what? They're already obsolete. Everything may be going 3D.
Later this week at the annual Consumer Electronics Show in Las Vegas, a slew of companies will be pushing what they hope will be the next big thing in TV: 3D movies and games — even new 3D HDTV broadcasts.
The only problem is that none of the equipment currently in stores and living rooms will be able to display, say, a 3D Blu-ray disc of "Avatar" or any of the forthcoming 3D broadcasts. Consequently, it will likely be several years before the technology becomes popular — if at all.
The push for 3D entertainment is currently focused on four areas: new Blu-ray discs, new television displays, games, and live broadcasts. Companies pushing 3D range from the likes of Panasonic and Sony to FujiFilm, Technicolor, Mitsubishi, LG Electronics, and reportedly DirecTV.
The first 3D products will likely come in the form of new Blu-ray disc players that conform to a new standard. The new players will spin discs at a higher speed and stream what are essentially two separate video feeds, one for each eye to create the 3D effect. The Blu-ray Disc Association claims each of the video streams will be at full 1080p HD resolution so that there will be no loss of sharpness or image detail compared to current Blu-ray movies.
"However, we're telling people they'll need to buy a new player," says Andy Parsons, a senior VP at Pioneer USA and spokesman for the Blu-ray Disc Association. According to the association, the good news is that Sony's PlayStation 3 can be upgraded via software to work with the new 3D discs. Everyone else will have to buy a new player, but they should all work with any 3D-capable HDTV, whether it's an LCD or plasma panel or a set based on DLP chips. Unfortunately, you'll still need to buy a new TV to get that 3D capability.
A 3D HDTV must display images at a rate of at least 240 Hz, for example. Some current sets can already do that, but they lack the circuitry to combine the separate video streams that are used to trick our eyes into seeing a three-dimensional picture.
Among the major set manufacturers, Panasonic seems furthest along in its 3D plans. The company has demonstrated the best-looking, most realistic 3D video yet on its plasma televisions. Panasonic plans to start selling the sets in 50-inch and larger sizes as early as this spring. The TVs display two separate HD video streams, rapidly flipping back and forth between the two. Switches between images from the two streams occur so quickly that viewers see it as one solid picture. However, in order for you to see the 3D picture, you'll also need a special pair of glasses.
The glasses aren't like the cardboard goggles that cost less than a dollar and are used in most theaters. That approach lowers the picture resolution of a home movie, and thus reduces the image sharpness. So Panasonic's technology (and similar technology used by Sony and others) uses glasses with timed LCD shutters that are electronically synchronized with the TV's display. Such glasses made by XpanD and others cost $50 or more, although a Panasonic spokesman pointed out that buyers would get at least one pair of glasses with the purchase of a new TV. (Large families may balk if they have to spend an additional $200 to enjoy family movie nights in 3D.)
While tech addicts will be able to buy new 3D disc players and TVs later this year, it was assumed by most industry analysts that live 3D football games or episodes of American Idol wouldn't be available for several years. There's no broadcast 3D standard, for example, and cable companies are already stretched to capacity trying to deliver HD channels; currently, 3D is beyond their abilities.
Satellite broadcasters appear to see 3D as a new opportunity to gain customers, however.
DirecTV launched a new DirecTV 12 satellite just before New Year's with the stated purpose of offering more HD channels to its subscribers. But several leaked reports claim that the company will announce plans to use the satellite to broadcast the first 3D HD channel in the U.S. as early as this March. Whether the rumors turn out to be true — and whether DirecTV can deliver on the promise — remains to be seen.
Nevertheless, the success of 3D movies like the record-breaking "Avatar" is encouraging consumer electronics companies and movie studios that the future is in 3D. So far, no company is saying how much more the new disc players or televisions will cost, but you can be sure that all of this new technology will cost you more.
