The upsampler and the D/A converters are fixed on an independent PCB plugged on the main board which permits easy possible upgrade. The USB type B digital output permits direct connection with a computer (PC and Mac) and accepts high resolution signals such as HD_Master (24bit/192kHz). Each digital input uses its own Digital Input Receiver for a lower level of jitter.
The analog stage includes four operational amplifiers typically chosen for their sound quality, their fast transitions and exceptional audio quality (very transparent, open & aerial) A user friendly digital screen shows the signal frequency of the selected input.
The new converters constitute the latest version of METRONOME TECHNOLOGIE Converters series , has inherited of the most recent developments and proprietary improvements performed by METRONOME TECHNOLOGIE with a very high level of quality achievement.
Main Highlights and Design Features: The two D/A converters using the best 24 bit/192 kHz technology with 32 bit internal processing permit fast music restitution with clearer and deeper sound.
The power supply with individual power transformers and completely independent regulation lines for each critical part of the converter – digital input stage, digital upsampling and processing, converter, analog output – provides an inter-stage EMI/RFI radiation protection to insure a dynamic analog-like sound quality.
The model C5 is a solid state version, becoming C6 with addition of tubes, and C8 includes a switch function from solid state to tubes and an external ELEKTRA power supply.
