Been in your position and the best I found with my set up is the AudioQuest Anaconda. I was using XLO reference Type 2 and was thrilled until I auditioned the AQ. No brightness, detail and no real character of it's own. Kinda spooky when you hear it. I picked up a .6 meter for $325.00 but you can find 1 meter pairs for under $500.00. Good luck and Cheers...
