Benchmark have announced their new Digital to Analogue Converter the DAC2 D. The DAC2 D has the same performance of the company’s DAC2 HGC but without the analogue inputs and the 12V trigger. Keeping the specs inline with DAC2 D, it has” lower noise, lower distortion, improved accuracy, outstanding musical detail, precise stereo imaging, an advanced digital filter design, and a new high-sample-rate Asynchronous USB Audio interface”. All inputs are isolated from interface jitter by Benchmark’s new UltraLock2™ jitter attenuation system. Internal digital processing and conversion is 32-bits, and includes 3.5 dB of headroom above 0 dBFS. Four balanced 32-bit D/A converter are summed together for each balanced output. Benchmark claim that the new DAC2 D has an analogue sound.

M2 Tech, the Italian hifi manufacturer that brought us the well received hiFace S/PDIF output interface and the Evo DAC, have introduced the hiFace DAC, an async 2.0 USB 384/32 DAC.

Details

The hiFace DAC includes: asynchronous data transfer mode on USB 2.0, compliancy to USB 2.0 Audio Class (no drivers needed for MacOS, IOS, Linux and Android), very low phase noise oscillators and last-generation conversion IC capable of 384kHz and 23 bits.
Windows users will enjoy it in Direct Sound, Kernel Streaming, WASAPI and ASIO (depending on the OS version), while Mac users will be able to take advantage from Integer mode and Direct mode.
While the hiFace DAC output is purposely designed to give its best with amplifiers’ and preamplifiers’ line level inputs, it may also be used to drive medium- and high-impedance headphones.

Amphion and Antelope Audio will be co-exhibiting at the Sound & Vision Bristol Show in the United Kingdom, February 22 – 24, 2013. The two brands are going to demonstrate a few different set ups, starting with mastering quality to easy-to-use desktop systems.

Visitors will have the chance to see for the first time in the UK the winner of the CES Innovations 2013 Design and Engineering Award, the world’s first 384 kHz digital audio preamplifier with integrated atomic clock – Rubicon.

In addition to seeing the Rubicon, visitors will be able to listen, and experience Antelope Audio’s 384 kHz USB D/A converters. The public will also have the chance to listen to original studio masters, from the same speakers with which they were mastered. Amphion Two15  studio monitors, as well as all other Amphion loudspeakers use waveguide technology and controlled dispersion,” which allow speakers to work in all acoustic spaces”.

British newcomer Computer Audio Design (CAD), is a specialist high-end audio company that aims to achieve the “finest sound quality from computer audio sources”. Designed and hand-built in the UK, CAD’s debut offering, the CAD 1543 DAC, has been built as a “no-compromise” asynchronous USB DAC.

The CAD 1543 DAC has been built on a design principle that seeks to minimise components in the signal path. The DAC is also unashamedly computer-orientated in recognition of today’s high-resolution digital music files and yet “has been designed to deliver the same natural, effortless sound that’s inherent in the best analogue source components.”

The CAD 1543 DAC is built around a dedicated, non-magnetic acrylic chassis, has been optimised to work with a computer and painstakingly designed to minimise disruption to the incoming signal. To this end, the DAC has a single high-quality USB input, plus one set of RCA outputs which the company says “enables the signal to pass through the DAC without encountering the highly degrading effects of unnecessary switching. It also allows a super-short signal path (of just 1cm) from the USB board to the DAC.”

Designed by Scott Berry, a British-based US-born electrical engineer, the 1543 DAC has been conceived over several years.

The CAD 1543 DAC also boasts “highly advanced” power supplies which have their own mains conditioning. The DAC also has a captive mains lead and eschews a mains power switch in keeping with the company’s fewer-components-means-better-sound philosophy. Further features include: extensive internal isolation; no active devices in the output and visco-elastic polymer feet.

Over 90% of the DAC’s components come from UK manufacturers, including the acrylic case, power transformers, PCB boards (and assembly), PCB supports, the LED backlight and mains power plug. The DAC is modular in design, allowing upgrades and updates to be added over the unit’s lifetime. The special acrylic casework also enables rear panel changes to be introduced cost-effectively if required, in the future.

The CAD 1543 is available now priced at £6,900 (standard finish) with custom finishes and colours available on request.

Sacramento based High-end audio manufacturer Light Harmonic has announced they will introduce the Da Vinci Dual DAC at CES 2013.

Light Harmonic’s Da Vinci DAC utilises unique, proprietary design elements to “set a new standard of fidelity and musicality in digital music reproduction”:

A 384K/32 Bit Asynchronous USB input which accepts 384K/32 Bit pulse code modulation (PCM) digital audio without artificial up-sampling.

3-L Buffering provides a jitter-free, three-layer elastic buffer between the music source and digital sample conversion, completely decoupling speed fluctuations in the source, and enabling Da Vinci to convert music samples using the most accurate core clocks.

3X Clocks provides on-the-fly selection of one of three highly precise -166dB phase-error clocks, according to the sample rate of the input file.

However, a DAC designed for PCM playback will not offer optimal performance with DSD, nor will a DAC designed for DSD extract the best performance from a PCM source.

The new Da Vinci Dual DAC eliminates all constraints in performance by providing completely separate and discrete decoding engines for both formats: one designed and optimized specifically for PCM, one designed and optimized specifically  for DSD–hence, the name “Dual DAC”.

The new Dual DAC will be demonstrated in a system featuring components from Dan D’Agostino, Wilson Audio, Pass Labs and MIT Cables.

Italian high end audio manufacturer Lector Audio has announced the introduction of their latest DAC, the Digitube DSD (Direct Stream Digital).

The new DAC is based on the  32 bit Dac from AKM and has an output circuit designed around vacuum tubes (ECC-81/12AT7).
The DAC accepts digital signals up to 192kHz/32bit and 384kHz/32 bit via USB. Also included are a word clock input and a SPDIF output.

Polish Hifi maverick Lampizator has announced two new products to add to their range of high-end audio products.

Lukasz Fikus, owner ad chief designer had the following to say about the Level 6 “…no compromise, ultimate attempt on the state of art in music making. It is not about convenience, not about features and not about specs. It is only about music.”

The level 6 is available only to special order with an estimated waiting time of 4 weeks. Price is €4900 (plus 20% Vat in UK)

The second product announced from Lampizator is the Silk AC filter with 4 outputs and for 230V. There is one CLC filter for each outlet “which not only filters the incoming signal but separates your gear from one another.” Price is €500 plus vat as a kit or €700 plus vat for the assembled unit.
