My system is (mostly) Bryston electronics and PMC speakers and, as Van Damme are the cables that PMC use, I've used them myself for several years. The problem, though, has been a maddening and persistent brightness in the treble and glare in the midrange, the only (not really satisfactory) remedy having been to insert fixed value cement resistors to the tweeters.
Over the past five years or so, I've gradually switched away from Van Damme cables to Studio Connections (Abbey Road) Reference Plus and, though expensive (but not as expensive as quite a few others), they're truly excellent, especially the speaker cables. I managed to get a 4m pair at a very attractive price and would recommend them to anyone (full RRP is £1,600/pr).
Van Damme's 110 ohm digital cable (with XLR terminations) is, however, very good (and wonderfully inexpensive), better than any of the many BNC-terminated ones that I've yet tried (including the one made by Studio Connections). It's the only XLR-terminated one that I've tried, though, so there may be better ones available, albeit with higher price tags. I'm currently considering buying a DH Labs Silver Sonic D-110 XLR digital cable, though at about £130 + import duties (from the US via eBay) and no returns, it could be a costly plunge if (in my system) it doesn't live up to expectations.
