jps labs vs less loss

my question is is either the jps labs ac power+ better than the less loss original? i have jps superconductor q for my ic and speaker cables and am now looking to step up the power cord. i am truly amazed at the diff the jps combo has made in the sound and am hoping for continued improvement
I had the jps labs power cord not the + and I had the Lessloss power cord. It has been a while so my memory is not the best, but I remember that in my setup the upper end was rolled off with the Lessloss and I disliked that plenty. I do not remember the JPS Power doing that. Others have reported lack of sparkle and upper end rolloff with the Lessloss. YMMV
