Several months ago I bought three of Don's Eminence power cords and put them on my power conditioner and mono block amps (300B's). To say it made a difference is probably the understatement of the year. I talked to Don recently and the "new" version is pretty much the same as last year's version. I hope that answers your question. But to elaborate a little, the eminence power cord made such a profound improvement on my system I would say that nothing has even come close to improving the overall sound of my system for the dollar spent than DCCA Eminence power cords. I proceeded to buy two more for CD player and phono pre-amp and my word the quality of sound went into the stratosphere. So what am I talking about ? Sound was more detailed with smoothness (not easily done), body of the music was richer with a fullness that wasn't there before, sound staging every which way was wider and deeper, and tonal realism of individual instruments was just plain more realistic. I hope this helps. To me you cannot go wrong dealing with Don at DCCA. If you don't like the sound of his stock cables, he can even tailor the sound to some degree to your liking. I found the Eminence to be so "perfect" for my system I did not find this necessary. If you are wondering how his cable stacks up to others, I do have a Purist 20th Anniversary on my pre-amp which beat out Don's Eminence only by a hair but for several times the price. Cost to performance ratio not even close for me. I recommend the Eminence power cord as the best improvement per dollar spent I have ever made in this hobby of some 30 years. Thank you.
