Jolida MD (not sure if the "other" Jolida they had issues with are still around, and don't care much if they are) is always a good place to investigate tube things, as they price things fairly without much hype (not much advertisement if any). I noticed Morrow Cables ( I use a few of their cables…they work well) is "partnered" with them…Primiluna is well made and seemingly well regarded with "premium" parts, etc., but costs multiples of Jolida products, and doesn't necessarily sound better, at least in my experience.
