Consonance Reference7 HD tube music server


The guys at Consonance have hitched their wagon to the digital audio road train with the Sovtek 6H30 tube-infused Consonance Reference7 HD tube music server. It’s a hard disk music storage device AND a network streamer with both single-ended and balanced outputs.

Here’s what Consonance refer to as “key functions”:

  1. Digital stream master network audio interface (24Bit/192KHz)
  2. Digital stream Hard Disk recorder (24Bit/96KHz)
  3. WI-FI/LAN Internet radio
  4. Upgrade operating system from USB
  5. 24Bit/192KHz D/A Converter with asynchronous upsampling
  6. Universal DAC for CD transports, The Consonance HD interface, DVD players, Blu-ray players, cable TV decoders and satellite receivers
  7. 6H30 tube output
  8. Three Group analog outputs (2*RCAs and 1*XLR Balanced ,1*RCA with tube ouput)
  9. Coaxial digital input for independence D/A Converter mode

“The Reference 7 High Definition digital music interface contains audio coding and decoding software that can process 24Bit/192KHz high bit rate digital master tape audio streams at very high speeds and supports the decoding output of all types of digital audio formats, such as (WAV/ FLAC/MP3). In the future, through firmware upgrading, the device will support even more audio formats.

It can also be used as a network music server center. It can support any network hard disc NAS and can share network resources through WI-FI/LAN. It can also be used as an Internet radio. With a built-in channel list, it can receive over ten thousand digital Internet radio stations from all over the world.

The Reference 7 adopts the specialized 32-bit high-performance embedded multi-media processor CPU, multimedia DSP chip solution and the reference clock system of the industrial-class digital phase-locked loop (DPLL) system, effectively reducing clock jitter in transmission of digital audio signals so as to achieve an ultra-low jitter index.

The Reference 7 has an 5 inch LCD display with a touch screen allowing the user simple operation. The screen can display the artist’s name/internet radio station information and the sampling rate. It also includes an easy to use high quality fully functioning remote control.The Reference 7 support control by computer/ipad/iphone/ipod touch and Google Android smartphone or flat computer…”
