I have the Jena Trinity ic's. I have been using them almost a year now. Theynare the XLR/Balanced variety of cable which I have used from pre to amp as well as source to pre locations. I have been very satisfied with these cables in all situations. They sacrifice very little detail and present a smoothing and warm tonality to the soundstage. The one time I felt a bit of loss in the resolution and detail i simply switched tubes and was again satisfied.
