yes they do. When planning to recable your system it is very important to try the same cable through out your system. If you dont you will never fully know what the brand of cable added or took away from your systems performance. I was using all transparent ultras which where very good but I tried the Harmonic Techs. and it was asthough someone lifted a vail of the vocals.And I also found out of most of the cables I tried they had the least sonic additive of any of them. And thats what you want a cable that doesnt add or take away.( they all do but you want it to be at the smallest degree possible so it allows you to hear you gear) And the harmonics worked for me. Needless to say I sold all my transparents and went HT. Good Luck
