First of all, a brand new USB interface allows you to use all common sampling frequencies up to 24 bit / 192 kHz. Also, this new interface allows playback of native DSD-files, without conversion to PCM. Furthermore, the HD12 has equal quality on the 2 optical and 1 coaxial inputs .
Versatility - With an HD12 you can upgrade virtually any system to Hegel standards. There is a very high quality headphone output, regular RCA phono outputs as well as true balanced XLR outputs. This means you can connect to any receiver/amplifier and/or subwoofer. However, the built-in and remote-controlled volume attenuator also allows direct connection to a pair of active loudspeakers or to a power amplifer. High End to the people.
Sound - New research in the digital domain has resulted in extremely low jitter levels. In particular, great improvements have been made to “skirting”, a distortion that reduces the timing and precision in the sound. You hear it very well in drums and dynamic elements of the music. Another large improvement comes in the analog part of the D/A-Converter. We are talking about a noise floor of -145dB. It means the HD12 brings out so much more of those tiny details that suck you in to the music.
Quite simply a significant upgrade and a remarkable D/A-Converter.
