Rather expensive for a couple of short cables...

 
All gear is expensive in Aus compared to elsewhere. And prices seem to have suddenly increased again in the last month. I paid $59 not $69 for that cable.

...there's also the possibility of a problem with your monitor XLR port.  (Since you were using  the quarter inch inputs before).

 
I'll check that out.

As long as you don't buy Monster cables. I switched to Mogami many years ago, and have not regretted it one Bit (pun intended ).

I'm no expert on cables and such but when I connected all my gear with Mogami cables all when quiet. Noise was gone. I even use Mogami cables for guitar etc. Not cheap cables for sure and maybe not the best but they are very good and I feel worth the money. I think your hearing your monitors clearer now as was mentioned. hopefully they are not damaged in any way. Hope you work it out.
