Hi Kenny,
I have four cmarc power cables - entropic, but not the latest stellar. I have no idea how they compare against other high-end cords. I bought them together with a discount because they are b-stock and I bought four. I was assured that they were indistinguishable from new and I've never been able to find a mark on them. My thinking was: getting all four at one time would/should make enough of a difference in my system, and that the discounted price would mitigate my losses should I decide to sell them in the future.
I chose them over other brands because of the numerous 6moons reviews. I know that six moons writers can be a bit wordy, obtuse and clever - no site or reviewer is everyone's cup of tea. However, I have followed the site for many years and feel I have a pretty good handle on Srajan's likes, biases, etc. LessLoss cables are all described as having high resolution, but not being nervous, edgy, shrill, (insert your favorite adjective here). That's exactly what I'm looking for in my system.
My system goals are great imaging, especially depth of field, and as high resolution as I can get without being too forward. My system does a that, and everytime I invest in what I think should be a meaningful upgrade, the system gets better.
Maybe not as helpful as you would like, but that's all I've got. As I have made other changes to my system, the cmarc cables have stayed and I don't think about power cords anymore.
