My guess is the RF is sneaking in the back door so to speak. If this is the case you will not get any improvement no matter how well shielded the input or power cables. When RF sneaks in the back door it comes in on the speaker wires & gets amplified by the negative feedback loop. There is no RF protection here. There is already RF protection at the input of the amp but none at the output. Almost every case of RF interferance that I have had better shielded input wiring would not solve at all. You could even ground the input & it would not stop the RF interferance as it was not coming from the input side. I would borrow some better shielded cables to see if it helps rather than buy new better shielded cables to see if it works. My guess is it won't, this way you will not have wasted any money on a fix that won't work in case it doesn't work.
Some times what appears as a flter network at the output of an amp can actually work against you by tuning the radio frequency in & making it stronger ensuring that it gets amplified. I had this happen with a headphone amp when driving anouther amp with it. Removal of the tuned circuit solved the issue, no more interferance. It was not an issue by the way when driving headphones only when driving anouther amp in this case.
I have been running unshielded cables for years now without any real issues.
