Digital Audio

The Memory Player

The best digital playback device that I have ever heard. Nothing else is needed to play back your favorite cd rips, hi-res files or thumb drives. Simply connect the Memory Player to your amplifier and listen to glorious jitter-free playback. I am listening to cd's that I had essentially thrown to the scrap heap because they sounded so bad fifteen and twenty years ago. I had no idea that they sounded so good. It is not the cd that is bad, it's the DAC, CD player or other devices used for playback. The engineers of the Memory Player have focused on eliminating the one thing that kills the sound of digital playback, jitter! Listen for yourself by calling for an appointment to hear this amazing device.

Analog Inputs and Outputs

One pair of D2D (DAC) analog outputs, True Balanced output directly out of the DAC chip to XLR and RCA outputs (RCA outputs are not balanced).

Output Impedance: 10 Ohms. Direct drive of any power amplifier from 5,000 Ohms to 1,000,000 Ohms input.

Analog Audio Output Voltages: 1.5 VAC in RCA, 3 VAC in XLR.

Subwoofer and/or Woofer Outputs (for Bi- and Tri-amplification): Up to 4 VAC are available on the dongle in RCA and XLR True Balanced.

Analog Inputs (for digitizing LPs and other analog sources, live recording, or as a preamp for line level sources): Four Inputs, RCA or XLR (balanced).

Dynamic Range: 144dB (less in lower bit depths).

Frequency Response: 10hz to 215khz (Note: Lower sample rates limit the high frequency response).

Input Impedance is 24,000 ohms.

Analog Input Performance
(Analog Inputs, Digitizing Analog, LPs, recording Internet or FM Radio or live recording)

Frequency Response: 0 - 192 kHz, ± 0.05 dB.

Dynamic Range: 144 dB, A-wtd.

Signal-to-Noise: 116 dB, A-wtd. 144dB at 64/192.

Weight & Dimensions

35 lbs.

17" W x 6" H x 18.75" D

Digital I/O

AES/EBU or SPDIF format, XLR connectors on Sync Cable, BNC on clock out.

Sample Rates : 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176 kHz and 192kHz

Bit Depths: 64, 32, 24, and 16 bit audio types, if played using the D2D DAC, or digitally out, IF a third party DAC supports 64 bit audio. If your DAC runs at a lower bit rate than 64, our Sample Rate Converter automatically detects your DAC’s resolution, and downsamples and dithers it to ANY bit depth, if required.

Clock Rates: 44.1 kHz to 768 kHz, including all standard rates with variable adjustment.

On-board Digital Mixer (for recording or digitization)

Resolution / Dither: For digitizing analog up to 64/192, please keep dither enabled for digitizing LPs.

Monitor Mixing: Any input to multiple outputs.

Metering: Peak levels to -120 dB on all inputs and outputs.

Dongle Connections

Audio Port: Bracket-mounted 25-pin female D-sub connector for low frequency analog audio input only (Bi- and Tri-amping or subwoofers). DO NOT USE THIS FOR AUDIO OUTPUT (see note above)!

Clock Sync Dongle: Bracket-mounted 15-pin high-density female D-sub connector for digital input and output, sync in and out (for clock synchronization with external DACs).

Cables (included)

Base and/or subwoofer analog output, digital output, balanced and single ended, RCA and XLR. Clock output and clock input, and clock synchronization using BNC. BNC to RCA or XLR output connectors are available.

Certifications: CE and FCC Class B.


M2Tech Hi-Face Evo
High-end S/PDIF Output Interface

Hi-Face Evo by M2Tech is the new statement in high quality computer audio interfaces. Hosted in a compact and stylish aluminum case, Hi-Face Evo is capable of flawlessly transferring audio data up to 192kHz, 24 bits to virtually every DAC or A/V receiver around, thanks to its comprehensive outputs set. Hi-Face Evo incorporates the same leading edge technology as the classic Hi-Face - with some plus. Asynchronous operation up to 192kHz is used in conjunction with proprietary drivers, which allow for Kernel Streaming, Direct Sound and WASAPI operation (the latter under Windows vista and 7). Windows and Mac drivers are already available. Very high precision, very low phase noise (jitter) crystal oscillators are used. To further improve their performance, they have a dedicated shunt voltage regulator, which ensures a very low noise and spurious-free supply. Hi-Face Evo is powered by an external power supply (not included), to avoid the dirty USB bus supply from negatively affecting Hi-Face Evo’s performance.

Orb Audio

Unlike many DAC manufacturers, ORB have taken a different path by not using the same old DAC chip seen in other DACs, instead they are relying on a Japanese made DAC from Asahi Kasei, and this chip can handle data rates up to 24bit/192kHz. Which means, the optical and coaxial inputs are 24bit/192kHz capable, and the USB port 24bit/96kHz.

Along with the digital inputs, there is a line level input to feed a legacy device into the headphone amplifier, an amplifier capable of driving 600ohm headphones with ease.

Finally, the USB port on the front panel can be used to playback music files from a USB stick, with capacities reaching the sky these days, the ORB can be your only music source as well.
This is an excellent sounding DAC that renders vocals with a natural smoothness that is free of glare or edge.
