Since my earlier post I have purchased Chimera Labs XLR, been an interesting sonic journey. Sounded good right from the start, (replaced rca AQ Saphire .. blew away) but the break in "100" hours was "sumptin" else.
I have a modest system but it had the solid sonic qualities that allowed these wires to bring out very pleasing nuances. I would have never guessed that wires need to be broken in, but they did change in staging, dynamics, and tonality. Very pleased with the end result.
