One concern I have is how well the clock in the DAC

connection between them to overcome this issue.

With your current Arcam Transport/DAC setup, try disconnecting this
clock sync link and listen if it makes any difference?

BTW the DAC and the analogue outputs in the squeezebox is optional to
use - the coax/optical outputs are provided for external DAC's like
yours. Though I have an aging audio alchemy dac-in-the-box (which does a
better job getting music out of minidisc than Sony's own DAC's), in the
case of the Squeezebox - the internal one does just fine ;-)

Hopefully the majority of your hard drive stored audio files will all be
in FLAC format if you are going to this much trouble. Low bit rate MP3's
will show up their shortfalls quite quickly on a squeaky clean path.
But, I'm not that fussy - just like listening to new music care of
Pandora :-)
