Try TMC white label interconnects. If those won't fix it, try another amp. I've never heard an A5, but I just recently bought an MF A300, and it's quite fatigueing, for me, and none of my cables fixed it. It's just sitting, unused, in the garage, for now.
I've always found "listener fatigue" to come more from components, and not cables. Cables can either mask problems, or pass them through.
Chances are, you'll never totally cure your problem with just IC's. You'll probably be able to mask it, to a point, but most likely only for certain recordings.
Good luck.
