I can't speak to Soundquest or BJC, but here's my two cents on your other choice. I've been unimpressed by IA so far. I ordered a $55 cable last week based on their website photo and description, as well as a phone call to their sales staff, and the cable they sent is completely different (correct part number, just a totally different cable). That was annoying enough, but they have since utterly ignored my attempts to contact them, hence me putting in my two cents.
