I have a 6' pr of LS-188's and I've got to tell you - THEY ARE THE BEST I'VE HEARD. I went through a TON of cables. (still have some of them)
XLO, Transparent Audio, Signal Cable, mas Grey, mas Black, Audioquest, Shotguns, SVT's etc.
You definitely get what you pay for. These cables paired up with the IC's (SQ-110) are transparent, open, smooth 'realistic' highs (no roll off), scary midrange (real). The bass is deep with NO roll-off. I am hearing music that I've not heard before. Detail, passages with inner detail I've never heard before.
