Thanks for posting this very useful info.
Good news for those irritated by recessed and cramped inputs/outputs. The Kimber Kable Illuminations D60 coax rca cable fits perfectly and secure in the Chord Hugo, as do the Herron RCA cables (RCA outputs), and Moon Audio's micro usb cables (blue dragon and silver dragon, starting at lengths as short as 6 inches) fit perfectly into the USB inputs...and all these made in America. And another workaround for the RCA connections (thank you ALO audio) is to buy a locking RCA cable, and simply remove the locking cap by unscrewing it and removing it. I have a pair of analysis plus cables that fit perfectly like this. I'd prefer to have recessed (protection) and small cutouts (less stuff can get inside), so glad to have these cables that work.
