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.

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 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.

PHS-Master is a MC cartridge only phono preamp using Lundahl step-up input transformer (OFC), followed by a non-negative feedback JFET and MOSFET gain stage that drives half of the RIAA EQ (passive). Then signal enters the second active gain stage built with paralleled MUSES-01 OpAmps. These new OpAmps are truly something very special and with JFET input stage. The MUSES-01 provides more gain and also takes care of the second half of the RIAA EQ (active). The MUSES-01 is connected to a very high-current MOSFET output buffer (similar to the buffers inside the HAS-M) that drives the output. The MOSFET buffer can drive even a speaker direct, so interconnect cables and following stages are not a problem.
All active stages in the PHS-Master are working in Pure Class A. The component selection is extreme - original Toshiba devices, non-magnetic resistors with OFC leads, special film capacitors, ultra-low-noise voltage regulators, oversized power supply and large custom power transformer.
The PHS-Master can provide an optional digital output for archiving vinyl to a computer or other digital recording device. The audio quality of the digital output is extreme. Customers can choose either 192kHz/24bit PCM or DSD64/DSD128 digital outputs
9 watt single-ended Class A no feedback triode integrated amplifier, valve rectified choke power supply.
Silver version adds Audio Note™ tantalum resistors, copper foil signal capacitors, Black Gate electrolytic capacitors in many places and HiB copper wired double C-core output transformers. Valve complement: 2x 300B, 2x 5687, 1x 6SN7, 2x 6X5, 1x 5U4G.

Producing a reference level full-range speaker is a daunting task. With the increase in size and number of drivers, the importance of proper execution increases exponentially. With The Joule series all options were on the table, only after evaluating the world’s best drivers and researching new cabinet materials did we start prototyping the design. Finally after nearly 2 years of development and multiple prototypes was The Joule Black born.
Like all models in the Vapor lineup, we begin by building the perfect cabinet. And with the Joule, the cabinet is a work of art all by itself. The construction consists of two independent pieces for the bass driver cabinet, and for the midrange/tweeter cabinet. Each piece isolated from the other via Herbie’s Fat Dots.
The bottom bass section is a stacked Birch-ply construction, with a tapering Transmission Line integrated into the CNC cuts. Using the CNC and assembling the cabinet this way not only gives incredible strength, but allows us to give the Transmission Line the ideal amount of taper from beginning to end.
The top section is also CNC cut stacked Birch-ply made in the same shape as the Cirrus cabinet, thus allowing us to take advantage of the Finite Element optimization that was engineered into that shape. The front baffle is made of 8 layers of high-density thermoplastic and aluminum sheet, which form an incredibly dense and strong launch platform for the music signal that is also well damped. To blend it all together visually are complex CNC’d 3 dimensional shapes, end result is a stunning visual creation.
And the drivers are just as beautiful as the cabinet. Providing the bottom end foundation is the Class Leading AudioTechnology 10C77 Sandwich Cone woofer. This woofer is an example of what can be built when cost is no object, and provides bass speed and impact unmatched by any other. The midrange is the AudioTechnology 15H SDKAM, a midrange that’s not only dynamic and engaging but also musical and romantic. And topping it all off is the RAAL 140-15D, in our minds the finest tweeter to be found at any price!
To top it all off only the finest components are used throughout the build such as Clarity MR Capacitors, Jensen 12ga wax/paper inductors, and Duelund resistors. The Joule Black is easily capable of differentiating sonic changes of crossover components, so we've chosen some of the finest as our starting point.
