what speaker cable do you use on the Evolution Acoustics MM3 speakers or Harbeth speakers.

Hi,

I own and enjoy the Evolution Acoustics MM3 speakers as well as separate system with Harbeth 40.2 speakers.

I mostly use synergistic research power conditioners and power cables so was wondering if anyone uses speaker cables for the Evolution Acoustics MM3 other than those sold by Evolution Acoustics.  Anyone try the SR Atmosphere 4 speaker cables on the MM3?  What about for the Harbeth?  Anyone try the SR Atmosphere 4 speaker cables on Harbeth ?
