I used a pair of the least expensive AQ cables (VDMXr or something) and although they seemed to sound fine, I upgraded to a VDM3 (1 meter) from the CD player to the DAC, and a VDM5 silver cable (.5 meter) from a Squeezebox Touch to the DAC. All work great and and the cable length seems to be irrelevant (I a/b'd them to test this) maybe due to the re-clocking ability of the DAC. The difference between the cheapest and most expensive of this group seemed minor, but it's there. Now I have an extra pair of VDMx cables languishing in my Cable Museum.
