rooExtend-Box: Plug-And-Play for Roon Extensions

As a result, only 16 bit / 44.1 kHz data is output via the DP-570 outside of an Accuphase system.
But even with a restriction to CD format, the interface problem still persists, because the player only outputs the data via 75 Ohm coaxial or (worse) Toslink, while on the other hand the RooExtend box as well as my Roon server “PrimeMini 5” only accept USB.

The tale about bad audio quality using S/PDIF or Optical transmission is a tale from the “old days DACs” where the clock for the DAC was recovered from the digital input signal and prone to Jitter. These days are gone and all state of the art DACs (like the ESS-DAC chip inside your DP-570) don’t care at all where the signal comes from. They buffer and re-clock anything and as far as no bits got lost (you will hear this as a “pop”) anything is perfect and Jitter really an issue of the past but still a “tale” that can be told

So if you like to use the DR-570 transport connect it via Optical and this box to rooExtend. The data will be transported to Roon by rooPlay, DSP filtered and after that sent to whatever DAC you like to use. This also can be the DAC inside the DP-570 which you also connect via USB to the rooExtend-Box (you need a USB-HUB). As far as I read the transport and the DAC act independently in the DP-570 so this setup probably will work. But you will be limited to 16/44.
