New toy syndrome? I have both HD800 stock cable and the Q cable (terminated in 4pin XLR). On the Stratus, I don't notice much difference. I'm fond of both. And it was really pleasant doing business with Steve. Below is my earlier post on this. But of course YMMV.
For my HD800, I have both the stock cable and a French Silk balanced (4 pin XLR) cable from Q Audio. I don't hear any noticeable difference between them on the Stratus. ( There could be subtle differences, but I have yet to carefully AB them.) With that being said, the Q cable is lighter, more manageable, and has better build quality.
