John Atkinson said that he heard a very slight improvement with a $300 AQ USB cable over a basic one when connected to the Off-Ramp 4, but found no measurable proof why that would be so. IIRC he said the basic cable actually had slightly lower jitter. When connected to a dCS Debussy, he said the sound was identical.
The Audiophilleo on its own, or other bus powered converters like the Stello U3 may benefit a bit more from a higher quality cable than converters that mostly or completely use their own power. Regardless, I think your money is much better spent on a SoTM card, Vaunix, or AQVOX than an expensive USB cable.
