@OP,
There are other right angle adaptors available.
I, too, had the same issue with my AQ cables. I even told Alasdair at AQ that their cables were far too stiff for normal usage. He did say using a right angle connector would do no harm sonically, as it is metal to metal connection.
You'll find a good selection on Amazon- up/down, right/left. I keep a few of each just in case I need one when I move equipment around.
Voodoo cable makes one, but you need to know how you want it oriented, and it costs $100. I bought one, and it is nicely built, but really not worth the cost. I am hoping to take it apart and see if there is a way adapt it to the AQ cables. My thought is that it would be great if each power cord could be adapted for easily for any users particular situation.
