How's the Pangea sounding? I only heard bad things about the Pangea power cords, so I would be less likely to chance their USB cable. I only heard good things about Analysis Plus's interconnects, so I would totally roll the dice on their USB cable line.
This Oyaide would have been in your budget

It's what I run into my iUSB 3.0. Coming out of the iUSB I have a Gemini which delivers a wide stage with excessive transparency. I alternate the Gemini with a Whiplash Polestar that may as well be the polar opposite of the Gemini, trading in the wide transparent sound for an organic signature that is hypnotic, and makes PCM far more listenable. There's a 2008 review that said it well - "All unnatural and amusical edge, grit, glare, and other nasties that compromise sonics and contribute to listening fatigue were eliminated". In fact the Polestar goes so far in this direction that I prefer using it w/o my iPurifier2, especially if I'm listening to DSD. I find the highs in DSD to be less "violent" and not as easily offensive, allowing for bolder electronics in the mix.
