The Hegel HD 20 (1400 euro) is a natural and powerful-sounding converter that has only digital inputs, but thanks to volume control can replace a pre amp.
- D/A Converter: Hegel HD 20
- Data sheet
The black converter of Norwegian origin for about 1400 Euro know already visually in scene to set – it is more than twice as large as a Musical Fidelity V-DAC or Furutech GT40 and has also a display – even if this gives no further information except the selected input. A USB interface for data up to resolution of 24-bit / 96 kHz intakes and an optical digital connection is found next to two coaxial.
About this, not just the music from the computer is transmitted, but she also commands of the enclosed mini remote control sends the play software – commands how to play, skip and stop of iTunes or Windows Media Player accepts. Logically, the volume can be controlled – on the Hegel himself.
So will Hegel HD20 even to the preamplifier, which can snap on the RCA and XLR outputs directly to active speakers or a stereo power amplifier. It worked surprisingly well in practice, especially as the XLR jacks with a 44 ohm output resistance are tolerant of longer cable runs.
Although the USB controller to access the USB data by tenor not by modern asynchronous mode is able, but the Norwegians around mastermind Anders Ertzeid have devised another method, to keep the jitter in chess. The incoming digital data are channelled through one of the most exquisite and expensive sample rate converter currently available on the market – the AD1896 by analog devices.
The exercise aims, the data buffers and own clock to bars, before the converter AD1955 to work. What brought the Hegel also prompt very good jitter at the laboratory test results.
Also the sound convinced all along the line. Powerful and physically with a fascinating naturalness he played at random through the music portfolio. Itself which by its high bit capabilities became the secret favorite of editorial M2Tech Young (test in AUDIO 4/11) had to be in the category space surrender, could but counter with slightly more finely woven textures and details.
