Model 2

The HD-Player Model 2 is a digital audio player meeting the highest demands concerning design, usability and sound quality

Model 2 Detail
The HD-Player Model 2 is designed as a fully integrated digital playback device, requiring nothing more than an amplifier and loudspeakers. The Player handles practically all digital formats available today at best-in-class sound quality. Controlling it is conveniently done via the high-resolution display on the front or via a mobile device, like a tablet or mobile phone.

The engineering effort is reflected in the implementation of only-the-best selected components as well as in the complex chassis construction dividing the whole unit in a number of separate compartments in order to minimize interference between the functional units or in the separate power supplies for each channel and each functional unit.

Model 2 Detail
The digital/analogue converter alone utilizes 3 torodial transformers. The two dual-mono converter boards are completely galvanically isolated to maximize channel separation and signal-to-noise ratio. The selected R-2R NOS converter chips feature integrated I/V-conversion, so that no external output stage is required. Since eight chips are implemented per channel, they produce sufficient power to drive any downstream equipment, so that the signal path is kept to an absolute minimum. The D/A converter has a completely symmetrical layout and utilizes high-grade Lundahl transformers to generate an analogue RCA output.

The overall result of all this effort is a breathtakingly realistic and emotionally involving listening experience. See for yourself what the experts say:

The renown online magazine HiFi-Statement has tested the HD-Player Model 2 in 04/2018 and expressed a “very strong recommendation”. You can find the full review here: www.hifistatement.net/tests/item/2310-digitale-audio-systeme-hd-player-model-2.

Germany’s largest HiFi magazine ‘Stereoplay’ has reviewed the Model 2 in its September 2018 issue and awarded it a Stereoplay Highlight. You can read the full review here: Sonderdruck Stereoplay 09/2018.

Highlights

Highlights

  • There are two options for control: either via the keys on the front panel or via a remote device (tablet or mobile phone – Apple iOS or Android)*
  • 2 high-resolution displays: one for user control and one for VU-meters (the displays can be switched off)
  • Completely modular design for upgradability and future-proofing
  • 4 TB of internal storage capacity (stores approx. 11,000 CDs in FLAC format); limitlessly extendable with additional storage modules**
  • Optional HDD- or SSD-drives for music file storage
  • SSD operating system and buffer storage drive for high-speed data processing
  • Support of all common audio file formats: Ogg Vorbis, FLAC, Opus, APE, WavPack, MP2, MP3, ALAC, MP4/AAC, AIFF, MOD, Musepack, wave files, Dff, Dsf etc.
  • Playback of all PCM-formats with a bit depth of 16bit to 24bit and all sampling rats of 44.1kHz to 192.0kHz as well as all DSD-formats to 128x
  • Playback of DSD 64x and DSD 128x via PCM-conversion to 24bit /176.4kHz***
  • Gapless playback
  • Optional up-sampling to 176.4kHz respectively 192.0kHz
  • Optional loudness normalization via ReplayGain****
  • Non-oversampling DAC; dual mono layout with eight DACs per channel operating in full dual-differential mode; no digital filters for an analogue sound image free from digital artifacts
  • No current/voltage conversion or analogue output stage for shortest-possible signal path
  • Completly symmetrical design
  • Pure class-A headphone amplifier
  • Full galvanic separation of all the boards to exclude any electromagnetic interference between them
  • Separate power supplies with torodial transformers for each channel as well as for the digital and analogue sections; additional separate torodial transformer for the headphone amplifier
  • Massive chassis construction optimized to minimize vibration and electromagnetic interferences
*An Apple iPad as remote control is included with every HD-Player
**Additional storage modules are separately available as optional accessory
***Conversion from DSD to PCM is a virtually lossless process (in contrast to conversion from DSD to PCM), achieved through a simple decimation filter. Since 64xDSD corresponds roughly to 20Bit / 96kHz and 128xDSD to 22Bit / 120kHz, a conversion to 24Bit / 176.4kHz PCM provides sufficient headroom to ensure full preservation of sound quality
****ReplayGain is an optimized RMS normalization, avoiding dynamic compression or other interferences with the original music
