Goldmund Telos Headphone Amplifier

A new Goldmund Amplifier is born and will be presented to you in Los Angeles in January. It is the Goldmund Telos Headphone Amplifier.

It can drive any headphone even the least sensitive ones, and adapts to any impedance.

Being a Telos, it brings exceptional dynamics (80V rails). It comes with built-in gain adjustment and its volume control is similar to that developed for the Mimesis 22H, with unique linearity and perfect channel balance.

Last but not least, Goldmund innovates again with the first headphone amplifier integrating built-in DSP that allows unique signal treatments like Time correction (Leonardo) or Binaural decoding, for continuous and smooth head tracking in all angles.

D’Agostino Momentum integrated amplifier

Industry awards and new Momentum integrated amp highlight D’Agostino LLC plans for 2014 International CES

At International CES, January 7-10, 2014, in Venetian Hotel suite 29-223, Dan D’Agostino Master Audio Systems will be debuting its new Momentum integrated amplifier and celebrating many recent honors from industry publications and organizations. The company invites and encourages CES attendees to visit the Venetian suite to audition its latest products.

The Momentum integrated amplifier brings many of the technologies from the Momentum amplifiers and preamplifier to a broader market. From the front, the integrated amp closely resembles with Momentum preamp, with the same illuminated indicator dial inspired by Swiss watches. Like the preamp, the integrated amp offers six balanced XLR inputs. It also continues the preamp’s bypassable tone controls for bass and treble, so the sound can be adjusted to suit the recording, the room or the other equipment in the system, all without affecting fundamental audio quality and musicality.

Using the same essential design concepts as the original Momentum amplifiers, the Momentum integrated amp delivers 200 watts per channel into 8 ohms and 400 watts per channel into 4 ohms, both rated conservatively. Like the originals, the integrated draws less than 1 watt of power in standby mode, and employs 1% metal-film resistors, 69 MHz output transistors

Berkeley Audio Design Alpha DAC Reference


Berkeley Audio Design is extremely pleased to announce the availability of the new Alpha DAC Reference Series.

The Alpha DAC Reference Series embodies everything we know about digital to analogue conversion taken to an unprecedented level – a level that requires new design concepts & new components at the edge of what is possible.  The result is an immediacy and presence of music reproduction that is simply real.

We literally designed the Reference Series before is was possible to built it.  Almost three years in development, the Alpha DAC Reference Series uses components designed to our specifications that were not commercially available.  Several suppliers were not able to meet our requirements which delayed the release of the Reference Series by more than one year.  But those obstacles were overcome and now the Alpha DAC Reference Series is a reality.

The presence & sonic reality of the Reference Series is the result of digital to analogue conversion at a new level of accuracy made possible by tremendous electrical & mechanical noise isolation coupled with extreme time domain stability.  Ceramic circuit board materials are used in all critical areas and the enclosure is carefully engineered to minimize electrical noise while maximizing mechanical stability.  The Reference Series weighs over 40 pounds and the entire enclosure is precision machined from a a solid billet of 6061 – T aluminum alloy.

A new high output, all metal IR remote control with direct input source selection is provided with the Reference Series.

Careful consideration was given to providing the highest possible reproduction of DSD files by the Alpha DAC Reference Series.  99% of modern DAC’s, including the Alpha Reference Series use mult-bit D/A converters because they provide better performance than 1-bit converters – even those who advertise “native” DSD compatibility.  So, at some point, the 1-bit DSD stream must be converted to multi-bit for all of those DAC’s.

We could, like many other manufacturers, convert 1-bit DSD to multi-bit within the Alpha DAC Reference Series and show “DSD” in the front panel display.  That would be the easiest approach from a marketing perspective.  But that would also mean increasing the amount of processing in the DAC during playback which would degrade audio quality, and audio quality is the reason the Alpha Reference Series exists.

Fortunately, virtually all reproduction of DSD files using external DAC’s occurs with a computer based music server as the source.  If the 1-bit DSD to multi-bit conversion is done first in the computer it can be performed with extremely high precision and superior filtering that preserves all of the content of the DSD file.  Computer DSD to multi-bit conversion can be at least as good as that performed in a DAC and without adding processing noise near or in the D/A converter chip.  Another advantage of computer based DSD to PCM conversion is that if higher performance DSD versions such as DSD 4x appear in the future they can easily be supported with a software upgrade.

For all of those reasons, DSD capability for the Alpha DAC Reference Series is provided by an included state of the art software application that provides either real time conversion of DSD 1x and DSD 2x to 176.4 kHz 24 bit PCM during playback or conversion to 176.4 kHz 24 bit AIFF or WAV files.  The software application is included in the price of the Alpha DAC Reference Series and is compatible with either Windows OS or Mac OS based music servers.

The Alpha DAC Reference Series supports 32 kHz to 192 kHz 24-bit PCM through four input; Balanced AES, Coaxial SPDIF 1, Coaxial SPDIF 2 and Toslink Optical.  Independent, single-ended and true balanced analogue outputs are provided.  Dimensions are 17.5 inches Wide X 12.5 inches Deep X 3.5 inches High.

Spectral DMA-300 RS and 400 RS Reference Series amplifiers

DMA-300 RS €23000
DMA-400 RS €43000 /pr

Spectral Audio is pleased to introduce the new DMA-300 Reference Standard amplifier, the second signature component in our Reference Standard line, Our first RS component, the DMA-400RS monaural amplifier marked the culmination of a multi-year research effort by our engineering team. Engineering director, Keith Johnson set as his goal for the new generation amplifier the elimination of subtle but intrusive energy storage artifacts occuring in active circuit devices. The solution, the creation of critical small scale driver and larger scale gain devices which exhibit virtually no energy storage or thermal tail memory represents a major advance in amplifier accuracy, and is fully implimented in the DMA-400 RS. Today, the DMA400 RS is recognized worldwide as an important breakthrough in high-end amplifier technology and a new reference for the most demanding system applications and the finest loudspeakers.

Upon finalization of the DMA-400 RS, Spectral engineers embarked on an even more challenging task, develop the first stereo reference standard from Spectral, and distill the unrivalled listening
experience of the DMA-400 into a single chassis component. Production cost or complexity would not be a concern.

- Replicate the unique "you are there" quality of the DMA-400.
- Parallel the extraordinary clarity and purity of the DMA-400.
- Equal the unprecedented settling accuracy and intertransient silence of the DMA-400.
- Achieve unmatched dynamic expression, drive and sonic "life" in a single chassis amplifier.

The DMA-300 RS is a high-tech showcase featuring cutting-edge component technologies from around the world. An exotic family of custom semiconductor devices and ultra-precision passive components has been developed with the assistance of some of the most advanced high-tech suppliers from the instrumentation, RF and microwave industries. In an approach similar to the DMA-400, unique high-speed transistors, exotic film capacitors, hand-calibrated resistors, high performance diodes and specialized magnetic components were all commissioned for Spectral's DMA-300 RS.

The result is a new standard for linearity and signal resolution in a stereo power amplifier. More important is the stunning natural clarity and listening involvement that results from these many advances. The DMA-300 RS reveals the true musical reality locked in fine recordings, a musical world that is absolutely compelling, immersive and more than a little addictive! The construction and component technologies of the DMA-300 Reference Standard are costly and select; they do not lend themselves to production efficiency, As a result, the DMA-300 RS will be hand-built in limited quantities similar to the DMA-400 RS monaural amplifier.

Product description
The NAGRA VI has been designed as the natural successor to the NAGRA-D / DII multi-track digital recorders. Based on a totally new design concept, the hardware of the NAGRA VI is software dependent and can be adapted simply through software. Available in a choice of three colours ("Slate" grey, "Midnight" blue and "Burgundy" red) allowing owners of two or more recorders easily identify a particular unit. The NAGRA VI is supplied with two plastic "handles" which serve not only to protect the front of the unit from accidental damage, but can also be moved to their lower position and serve to tilt the recorder for a better viewing angle, and easier access to the functions when working on a table-top or sound cart. A carrying case and shoulder strap are also available for over-the-shoulder operation.
The NAGRA VI is delivered with a removable battery box containing a lithium-ion battery pack, a mains power supply and is equipped with a 120GB internal hard disk.

Audio inputs
It offers six independent analogue audio inputs. Inputs 1 - 4 are equipped with traditional NAGRA microphone pre-amplifiers for dynamic and phantom +48V microphones. These pre-amplifiers are a combination of those developed for the NAGRA V and NAGRA-D and are without doubt the best audio inputs NAGRA has ever designed. An audio limiter can be selected for each of these inputs and these can be ganged in pairs if desired. These totally new concept input circuits offer the best specifications ever produced by any NAGRA in terms of pure audio quality. The four "In-house" transformers offer fully floating inputs for the dynamic microphones, giving a greatly improved signal-to-noise ratio. The remaining two analogue inputs are LINE level inputs for connection to other equipment supplying a line level signal, such as radio receivers. When set to the LINE position all 6 analogue inputs will accept up to +24dB. The two input connections (channels 5 + 6) double up as 2 AES inputs (A and B) when selected to digital input mode.

Zipper noise suppression
The NAGRA VI does not use traditional logarithmic potentiometers for the audio levels as were traditionally used on previous Nagra models. Today digital “encoders” are preferable because they do not suffer from “crackling” noise problems, and can be programmed to fulfill a multitude of different operations depending on the software program controlling them. Equally, even the graduation of the sweep is software calculated and can be altered relatively easily, rather than being created by the precision winding of the internal coils during manufacturing.
However, such encoders normally suffer from a phenomena known as the “Zipper” noise. The NAGRA VI benefits from a complex development in a suppression system used on every level control of the recorder. The end-result is that the potentiometers can be moved instantaneously and no digital zipper effect can be heard.
The potentiometers on the Nagra VI behave in exactly the same manner as the traditional logarithmic potentiometers used in Nagra analogue recorders but with the advantage of the precision offered by digitally controlled encoder devices, and hence an increase the perfection of all recordings.

The left side panel clearly shows not only the analogue and digital audio input connections, but also the external 4 pole XLR DC input socket, allowing the NAGRA VI to be externally powered from an external DC power source such as a car battery. The 5-pin LEMO SMPTE/EBU time code In/Out can also be seen as well as the two HIROSE connectors used for powering external accessories such as radio receivers. These two connectors can supply up to 1 A at 12V.

The right side of the recorder is where the removable compact flash card is located. A LED next to the slot indicates when the card is accessed. The stereo analogue outputs, and the main AES out as well as the second headphone connector can be clearly seen. Additional AES outputs are located on the 15 pin Extension connector. The Start / Stop terminal is a fader start (contact closure) command as found on other NAGRA recorders. Two USB (host / device) connectors are also located on the right side next to the card slot.

Recording medium and format
The NAGRA VI records to a 120GB internal 2.5" hard disk. An extractable compact Flash card is used to record a copy of the audio tracks depending on the users track selections. The NAGRA VI allows approximately 20 minutes of 6 track 48 kHz 24-bit recording per GB of available disk / card space. The compact flash card section is equipped with a "Hot-Swap" possibility meaning that the CF card can be removed and replaced while the NAGRA-VI is powered up, without causing any damage to the card or the recorder. The NAGRA VI records using Broadcast Wave File (BWF) format and is iXML compatible for the metadata making the files compatible with all modern post-production equipment.

The NAGRA VI is equipped with a sunlight-readable 3.5" colour TFT display with a resolution of 320 x 200 pixels. This specially designed high luminosity display is used to visually indicate not only the status of the NAGRA VI but also the bargraph modulometers, take number, time code and the current operating modes of the machine. When in the menu mode, the audio levels can be monitored using the LEDs on the front panel.

File back-up
The NAGRA VI is equipped with two USB 2.0 ports. One is designed to connect the NAGRA VI to a computer for file transfer. The second is a "host" connection and although currently unused, it is planned to be used for connection of an external device such as a keyboard.

Time code
The internal time code system and all the internal digital electronics of the NAGRA VI are clocked by a crystal which is a "Stratum III" TCXO which has been artificially aged in an oven to maintain stability. This crystal gives a guaranteed overall stability better than ±4.6ppm over a period of 15 years throughout a temperature range from -20°C to +70°C. The drift due to temperature changes is less than 0.28ppm. This is the most accurate crystal ever used in an NAGRA recorder. The NAGRA VI will handle all the standard SMPTE / EBU frame rates as well as the 23.976fps rate for the HD format. All the frame rates can be pulled "up/down" for the NTSC markets.
