But how does it sound? You're the first I've heard of a "fit and finish" problem with the gemini. Them again I've only read reviews. I do own the iusb, I'm interested in the gemini. Right know I use an AB systems cable (not the one with the separated power and data lines). Having nothing to compare it to I don't even know if the AB makes a difference in my system. I'm not even sure if the iusb makes a difference in my yulong u18 (without the optional power supply[it fried out on me before I bought the iusb]) being fed to my yulong d18 via the aes/ebu.
