Viejos paños para limpiar discos y cintas de Realistic

Me los acabo de encontrar, ya ni los recordaba. Vendidos en Radio Shack, este lo compré a fines de los 80's inicios 90' tal vez. ¿Qué es  tal vez lo más sorprendente? Que es Made in USA.

Bello y gracil pero preciso y certero Grace m903

Este es un tiempo de resurgimiento del DAC que venía en picada hasta hace unos años.

 

He tenido oportunidad de conocer y usar para pruebas y desarrollos esta excelsa unidad que ofrece muchas ventajas por un precio muy razonable.

 

Es un DAC, es un pre con dos entradas análogas y un amplificador para audífonos. Puede operar en mono, tiene control de balance y salida de audio variable y un sonido que lo tiene altamente calificado y valorado en publicaciones especializadas.

 

Nacido desde el audio profesional es un equipo que suena magníficamente para el audiófila que no quiere trucos ni "cosmética auditiva" sino pureza y neutralidad pero que a la vez suena grácil y placentero, bien, en poca palabras. 

 

Yo lo uso en conjunto con otro equipo de audio profesional el SPL Volume 2, limpio y transparente y con un Odyssey Khhartago Extremecomo equipo de prueba base y el resultado es excelente.

 

Aunque similar en principio a Benchmark a mi parecer ofrece un sonido  más vívido, que involucra y sin perder precisión, naturalidad ni neutralidad es mucho más vinculador con la música.

Este equipo así como la gama completa de Grace Design empiezan a ser promovidos por www.armonia-av.com en México.

Ten years ago, we launched the model 901 headphone amplifier. 4 years later, the m902, which set the standard for a new category of compact, precision playback tools. Today, we proudly unveil the m903, which is simply the most refined and feature rich headphone amp, DAC and compact monitor controller available.

The m903 keeps everything great about its predecessors, adds some useful new features, and ups the ante with even more breathtaking audio performance. A new volume control provides higher headroom and lower distortion and noise. New generation DAC's and ultra-low noise balanced current to voltage converter yields even more musical performance compared to the m902. Improved s-lock PLL circuitry delivers even lower phase noise and jitter. An improved power supply isolates headphone amplifiers, line amplifiers, DAC's and digital logic, resulting in lower noise and distortion.

Perhaps the most exciting improvement is the all new high speed USB interface. This cutting edge technology provides a completely asynchronous data transfer mode which allows for bit-perfect USB playback with zero interface induced jitter. This new interface affords standard driverless USB Class 1 operation on Windows and Mac up to 24bit/96kHz and USB Class 2 audio for 24bit/192kHz operation on Windows and Mac (drivers needed for 192kHz operation under Windows). This is computer-based audiophile playback, perfected.

New crossfeed circuitry is even more useful and includes a gentle compensation to eliminate the perceived loss of low frequency content. Both balanced and unbalanced line outputs are now standard, with individual volume controls for each. We have even included a mono mode for checking a mix for phase issues or simply monitoring in mono. These improvements cement the m903 as the perfect compact, audiophile grade monitor controller, even for larger scale production environments with more than one set on monitors.

A full complement of analog and digital inputs are provided (balanced, unbalanced, AES3, S/PDIF, TOSLINK and USB), which are selectable via a precision rotary front panel switch. And we offer an updated optional infrared remote control, which provides essential control for anyone working out of reach of their m903.

Optional m903 Infrared Remote Control

Advancing the tradition of unmatched audio performance and functionality, the m903 is now the ultimate solution for high resolution audio playback. From the very top mastering engineers to the most discerning audiophiles – it is a must for anyone searching to discover new depths in music and sound.

Antelope presenta su primer DAC DSD el Zodiac Platinum

Un nuevo y reconocido fabricante que ahora dará más de que hablar con este nuevo y sofisticado equipo.

 

The widest DSD support and sample rate Zodiac Platinum DSD DAC provides the widest DSD support, including the unique 256X mode and a sample rate of 768 kHz via a custom-built USB chip. The extreme DSD256 greatly extends the accuracy and transparency of the audio reproduction as well as the overall system performance. The custom-designed Antelope USB chip compliments high fidelity by reducing clock jitter and pushing the envelope of the USB streaming with sample rates four times higher than those offered by similar devices. Whereas many top of the line DACs offer PCM upsamplers, the Platinum is the first device to offer a DSD upsampler. This distinctive feature allows the upsampling of DSD64 to DSD256, pushing DSD noise into higher frequencies, vastly improving the quality of the D/A conversion. The Platinum bypasses internal digital filters built into the DAC chip by implementing a custom upsampler with carefully designed high-precision linear phase filters in the FPGA.

Signature Antelope clocking In the heart of the new Platinum lie the renowned 64-bit Acoustically Focused Clocking and the ultra-low jitter oven-controlled crystal oscillator, which are Antelope’s signature for unprecedented sound quality appreciated by the best recording, mastering and post production studios around the world. In addition, the Platinum is equipped with a 10 MHz input for the legendary Antelope 10M Rubidium atomic clock, providing the most accurate and stable clocking reference and therefore an uncompromised digital to analog conversion. Distinctive pedigree and highly evolved technology Zodiac Platinum has inherited the stepped relay volume control and the dual stage headphone drivers with impedance control from its very successful and highly appreciated predecessor Zodiac Gold. The Platinum also comes with an elegant remote control and has the option for external audiophile grade power supply Voltikus. In addition to the PC and Mac control panels available in the Zodiac Line, the Platinum also offers the comfort of the remote control from a mobile application, available for Android and iOS.

Parasound Ships Computer-Based CD Player
By Joseph Palenchar On Jan 4 2013 - 11:29am

Parasound’s $4,500-suggested Halo CD 1 incorporates a CD-ROM drive and Linux-based computer.

 

San Francisco — Parasound launched a new home CD player that uses a CD-ROM drive, internal Linux-based computer and proprietary software to deliver a “nearly bit-perfect data stream,” the company announced.

The $4,500-suggested Halo CD 1, which is shipping, “demonstrates that CDs can sound significantly better than anyone has imagined possible," said president Richard Schram. "The full potential of the 16-bit CD format is realized for the first time in the CD 1," he contended.

The player’s CD-ROM drive runs at four times the speed of a conventional CD player drive to read every part of a CD as many times as needed to significantly reduce read errors and thus reduce the need for error-concealment processing that yields negative audio effects, the company said. “This sophisticated process almost always results in error-free data,” the company contended. “When interpolation techniques are needed, they are confined to [a] single small bad fragment [sample], thereby minimizing their negative sonic side-effects.”

The player accumulates all of the data read by the drive in a memory buffer for data-error analysis and processing performed by an onboard Intel ITX computer, which runs the Linux operating system kernel and proprietary software from Denmark-based Holm Acoustics. Details of the technology can be found at Parasound’s website.

Standard CD players, in contrast, do not read disc data nearly as quickly, transferring data to a DAC as soon as it is read from a disc. As a result, “they don't have time to accumulate enough data in a buffer so that it can be analyzed and processed,” the company said.

Like other Halo-series products, the Halo CD 1 features an aluminum chassis with extensive shielding for electrical and mechanical isolation. It also features three separate power supplies for the analog and digital circuits. The outputs use balanced XLR connectors, gold-plated RCA outputs, and S/PDIF Digital audio outputs via 75-ohm BNC, coaxial and optical connections.

A Discrete OpAmp selector lets users listen to the analog outputs directly from the low-noise National LME49990 op-amps or through discrete transistor-output stages to subtly changes the sonic character of the CD 1.

The player, already available in silver or black finishes, will be displayed at International CES.
