Wanted to add my voice to the choir and sing the praise of the CPT cables. Added a single 150 to my pre amp about 6 weeks ago and have now got to a point where I am really somewhat awe struck by what this single cable can do. Have been putting systems together for 35 + years and outside of speaker changes this is one of the most significant improvements I've ever gotten.
If you try one be patient in my system had some big time peeks and valleys in sound while breaking in. At about 350 hrs now and still hearing improvement. Definitely want to put one of the high power units on my amps.
