I like Harmonix very much.As Audioquest4life I am thinking same way about slight loss of the highest frequencies but when listened to them for longer period of time found out that I actualy like it this way.I am listening sometimes for long time and before using this cable I was getting tired and getting headaches very easily,now all that disappeared,I can listen and listen.Also those higher frequencies heard before seem to me now as unrealistic and synthetic.Also the placement of the instruments are excelent.
