I purchased a 2 run bi-wire set of AP Oval 12's for my Maggie 1.5's. Out of the box they were disappointing - very thin sounding. After 50 or so hours they are starting to sound better and I hope they continue to get better. Regardless of what people say about the quality of cables and whether or not they have a break in period its my observation that in my system they are changing for the better over time but I think its going to take quite a while before they settle in - maybe 250 hrs or so. Hey this is just my opinion....
