It appears from your system description photos that the length required for this cable is fairly short, probably around 1 meter. Keep in mind that the relatively short length, the fact that the interface is balanced, and the fairly low output impedance of the QB9 will all work in the direction of reducing sensitivity to cable differences.
My suspicion is that you might be pleasantly surprised with the results you would get by spending $80 on a pair of Mogami Gold Studio.
Another factor which may contribute to Mogami being a suitable choice is the proximity of the cable to the laptop in your system. Mogami Gold Studio is known for providing excellent noise rejection, and the electrical noise radiated by the laptop and/or its power supply could conceivably be significant at that close distance.
Good luck. Regards,
