A little confused (rBlink)...

I'm not an audiophile, but I have been learning more and I find all the tech intersting. In John Atkinson's Follow-up (p. 105), John explains his experience with testing and listening to the rBLink Bluetooth receiver D/A processor. At the very end JOhn suggests "plug the Arcam's S/PDIF output into your high-end D/A processor and you have a convenient and legitimate source of music." Here's where I get confused. Isn't the whole point of the rBlink to be the D/A for the source that is sending music to it via Bluetooth? If one uses the digital output from the rBlink, isn' the D/A on the rBlink being bypassed and the Bluetooth data is simple being passed to the external DAC? What value does the rBlink offer if you use the digital output? 

Thanks,

Allan

The rBlink's internal DAC is okay, but if you already own a higher quality D/A processor, the best sound will be obtained by driving that processor from the rBlink's S/PDIF output. Bluetooth data needs to be unpacked and decoded into standard linear PCM before conversion to analog and most DAC's cannot do that. They expect instead to receive PCM digital data and the rBlink povides that from Bluetooth sources.
