I'm a little late doing this -- I thought I already had. I wrote to Drew asking about a cable upgrade for my Ultrasone 900's, thinking I ought to go with the copper-based dragon cable (Black Dragon, I think). He recommended Cardas instead, and I went for it, getting a length reduction and 90 degree miniplug. Drew was dead on that the Cardas would tame the ultrabright Ultrasones, and they are so much more than I had hoped for now. It would surely have been easier for Drew to just sell me what I asked for, but he went the extra mile and I am very grateful.
I look forward to more business in future with Moon-Audio and I whole-heartedly recommend it to everyone else.
