I have recently replaced really good cables with Audio Sensibility cables after making multiples comparison. First, I sold my beloved Transparent Premium USB cable after a really long comparison with a special beta cable made by Steven Huang of Audio Sensibility. A double header cable made with more OCC silver than his current Statement offering. Steven knew that I tried about seven good to really good USB cables including his Testament. The Transparent Premium was my favorite follow by Audio Sensibility Statement. Both cables were superior to the Audioquest Diamond, Oyaide Continental 5S and Silnote Poseidon in my System. Steven Huang is a man whl loves challenge, so he ask me to be a beta tester for a Signature USB a couple months back. I never thought my Premium will be beaten but that' s exactly what happened. So lately, i told to myself, why not trying his Signature XLR against my stellar Audioquest SKY, fantastic cables on their own. I ended up selling the AQ SKY last week. Finally, in the same time I moved my headphone set up in my living room so I needed a longer cable for my Audeze LCD-2v2. I found a used Audio Sensibility Statement in 12 feet lenght. I'm now settled with mostly Audio Sensibility cables and I'm really, really pleased with the performance and quality I get for the money. If I have to put one quality that give AS cables the edge over other cables I tried is musical smoothness. At the same time, all the details and dynamics are there but with an incredible fluidity. Kind of hard to descibe without experiencing it. Anyway, I think with the 30 days money, anybody looking for really good value should give Audio Sensibility cables a serious look. I doubt that it will cost you shipping cost for return. Beside, Steven is certainly the kindest personne with who I ever dealt in this hobby.
