Yoby,
I am using pure solid core 99999 silver soft annealed bi-wired speaker cables.
On my speaker crossovers I have installed the WA quantum speaker chips, over them I have the Audio Magic PEA.
Near the end of the speaker cables I have the Audio Magic Speaker clarifiers. And then finally the Synergistic XOT's.
Each was installed seperatly with the XOT's added last.
With the SR HFT's and the FEQ unit, I have now the BEST sound I have ever heard!
Soundstage is huge, deep, the bass is really deep and well defined. There is such a lifelike image that I swear it can't get any better!
Somewhere down the line I will try removing some of the tweaks to determine just how much each one is contributing to the glorious sound.
