The HD-DAC1 is an ultra-high quality dedicated Headphone Amplifier, that
creates simply amazing sound because it uses amplification technologies
from Marantz’s high-end Premium 11 Series. The HD-DAC1 is so powerful,
it can even drive audiophile high-impedance headphones of up to 600
ohm – with complete MODE ease. All thanks to its three-level gain control,
Marantz HDAM-SA2 modules, a high current audiophile DAC (CS4398),
and its Premium Quality fixed and variable RCA outputs. It is so powerful,
it not only drives headphones, you can also directly connect it to your Hi-Fi
integrated amplifier or to a pair of active speakers or power amps. It’s also
highly connectable. Optical and coaxial digital inputs as well as a USB-B
port enable you to stream music directly from your PC or MAC. iDevices
can also be connected via the USB port on the front. For even more
connectivity we have also included an analog input. The USB-B works in
asynchronous mode to support not only 192 kHz / 24bits high-resolution
audio but also the DSD 2.8MHz and 5.6MHz for maximized performance
and the most direct way to enjoy excellent quality. To safeguard quality
when connected to a computer, we built extended isolation around the
USB-B input to eliminate the chance of high frequency noise generated by
the computer entering the HD-DAC1. We even included a jitter remover
and Dual Clock for extreme accuracy. Without doubt, the HD-DAC1 is a
feast for the ears. It also looks good. Info on volume, input, resolution,
etc. is shown on the stylish Marantz Porthole Display. While the solid
aluminum front is supported by a double layer bottom plate and retro-style
side panels. Pure craftsmanship

DAC1 Review – John Marks, Stereophile
by Benchmark Media Systems July 20, 2003

DAC1 ~ Stereophile
Benchmark DAC1

DAC1 – «Genuinely High- End»
«At $850, the Benchmark DAC1 is, in my experience, the lowest-priced piece of digital gear that can give sonic performance that is not just improved mid-fi, but genuinely high-end.»

«This column will examine two bits of kit from the polar ends of the price spectrum: Benchmark Media System’s DAC 1 ($850), and TEAC’s massive two-box Esoteric P-70/D-70 CD playback system ($14,000).»

«The Benchmark was slightly more articulate in the musical line, and slightly more detailed in spatial nuances, particularly the localization of individual images in space, and in soundstage depth.»

«All you need is a transport to feed the DAC1, a digital signal, a power amplifier, speakers, and a few bits of wire, and you have a stripped-down hot rod of a system that is ready to rock’n’roll.»

Evolution. Changing times call for changing tools. That’s why our new multi-format player is the natural selection for the next generation of DJs.
It’s been 15 years since the genesis of Pioneer’s first CDJ deck, which led to the world-beating CDJ-1000 series.

Now it’s time for something completely new.

Introducing a major leap forward for the club standard CDJ series: the CDJ-2000 – our new professional player for the digital age.

The CDJ-2000 fizzes with fresh DNA and can play music from multiple sources, including CD, DVD, USB storage devices and SD memory cards.

It also comes with the revolutionary music database management software for DJs: rekordbox™. Based on our ‘Prepare & Perform’ concept, rekordbox works (for both Mac and PC) like the leading music database management software, but is more creative and more DJ-friendly.

rekordbox allows DJs to prepare more before their performance and opens a door to tools such as Hot Cue Banks and Quantize, for perfectly synced loops every time. DJs can then export data to a USB or SD device to access vast libraries of music files and perform live – without the need for extra equipment or any inconvenient rewiring in the club.

Through the industry-first Pro DJ Link, music files and database data on one single USB or SD device can be shared simultaneously by up to four players connected via LAN (local area network) cable.

Plus, the data history of each DJ set is automatically saved and can be made into a playlist that can be loaded back into rekordbox.

Another key facet of the CDJ-2000 is its advanced HID (human interface device) and MIDI capabilities for native control of DVS (digital vinyl systems) via USB. What’s more, it achieves Pioneer’s highest sound quality to date through an improved audio output circuit, a new audiophile-pleasing Wolfson DAC processor, and a built-in 24-bit/48 kHz sound card.

Naturally, the CDJ-2000’s layout is related to its robust, reliable predecessor, the CDJ-1000MK3. However, although it fits easily into the MK3’s footprint, it ramps up performance with the largest (6.1-inch) clearest full-colour screen in the business.

Below the screen is an industry-first waveform Needle Search™/Needle Drop ribbon, so that all the convenience of direct file browsing can now be found in an intuitive hardware format. Add to these features a highly evolved illuminated Jog wheel, and an overall enhanced design, complete with carry handles and Kensington lock, and you have the ideal digital innovation for total performance and seamless synchronisation.

FEATURES
High performance 96KHz/24bit USB DAC and ADC IC chip
Enjoy audio in high resolution at 96KHz/24-bits surpassing conventional 44.1KHz/16-bit standards
Incorporates the most trusted driver in professional audio for 96kHz recording and playback
External power supply: while a USB-powered device might be convenient, it won’t develop the power required for high resolution playback, so we designed the GT40 with an external power supply to solve the problem.
Headphone Amplifier: It contains a high performance headphone amplifier with ample drive for good headphones
Analog-to-Digital Converter: The GT40 sports a high-performance ADC IC chip for high resolution recordings via analog inputs including phono, AM/FM radio, or other analog signals.
Phono Preamplifier: A first for this class, the GT40 features a phono equalizer for recording your precious LPs. Switch between Moving Magnet (MM) and Moving Coil (MC) or Line input
Highest Quality Parts: The GT40 features a high quality amplifier and condenser supporting its high performance analog circuit
High End Audio Grade Connections: The GT40 is equipped with gold-plated Teflon-insulated RCA jacks with an extremely high quality aluminum chassis and machined volume knob.

USB Playback Resolution : 24bit/96KHz
USB Recording Resolution: 96kHz (Max) supports 32kHz/44.1kHz/48kHz
Frequency response: 20Hz ~ 20kHz (40Hz: +0.5 dB, 15kHz:-0.5dB)
SN ratio:-90dB (A-wtd) / Line Output
Line Output Level: 1 Vrms
Line Input Level: MC 0.4mV / MM 5mV / Line 1V
Headphone Output Level: 80mW ( 32 ohm ) Max.
Power Supply AC Adaptor Rating: AC 9V 0.5A
Dimensions: 150 (W) x 111 (D) x 57 (H) mm
Weight: 785g Approx.
The load (Input impedance) for the ADL GT40 is as follows:
Line 50K ohm Approx.
MM 46K ohm Approx.
MC 10K ohm Approx.
Maximum Input Level for MM: 5.0mVrms at 1K Hz
Maximum Input Level for MC: 0.4mVrms at 1K Hz
Maximum Input Level for LINE: 1Vrms at 1K Hz
The Gain setting for the ADL GT40 is fixed at 62.5dB for MC and fixed at 48.5dB for MM.
(MC input to LINE output) => 62.5dB @ 1K Hz , +6dB(Line)
(MM input to LINE output) => 48.5dB @ 1K Hz , +6dB(Line)
GT40 has no setting for gain to match different impedance headphones. We recommend using 16 ohm to 300 ohm impedance headphones.

IMPORTANT NOTE FOR RECORDING:
The TENOR chip used in the GT40 has a bandwidth limitation of 12Mbps (USB 2.0 full speed operation), and due to this limitation only one I2S input or output can be set for 24bit/96KHz application at one time. Therefore, under this condition, for simultaneous multiple-channel applications other I2S interfaces must be configured at 16-bit/48KHz or 16-bit/96KHz. In other words, when recording it is necessary to set the audio Input on the computer to 24bit/96KHz (PC-Sound application; MAC-MIDI application), but do not set not the audio Output to 24bit/96KHz. The Output should be set to a lower 16bit resolution until recording is done. Then when you want to playback your 24bit/96KHz files through the GT40 you need to reset the output to 24bit/96KHz and reset the input to a 16bit resolution,
