I've been using the BL-1s in my system for a couple years now, and after comparing them to some of the best around I can say without hesitation they're an outstanding value. They might not offer quite the fullness of tone and harmonics of the high-buck interconnects and the upper frequencies can sometimes get a little smeared, but their transient speed, dynamics, transparency and detail are up there with the best. I think this is due to DH Labs' effective use of silver along with copper in their design, and they can make even top copper-only cables seem a little thick and slow by comparison. If you have a bright system or are looking for an overly lush midrange these might not be appropriate, but if you're after a neutral and detailed presentation these should be near the top of your list and could save you a bundle. Best of luck.
