the Bolder cables work well for me.
I had previously tried Canare 4S11, which I found a bit better than the HD wire, extension cord, etc. - but only if unterminated. I use it in the HT rig now and it does well enough.
The Bolder M-80's are all I have tried of the Bolder speakercables. They could do a lot of things better, but for the cost I am VERY pleased.
Rather than go on about air, soundstage, and immediacy - let me put it this way: with the M-80's in place, swapping a Bolder Type 1 and Bolder Type 2 cord around in the system had a startling impact. You could hear it before. Now, it sounds like a component change. And this is just moving a cord between components...
