Given your quest. I would recommend Cardas. Transparent... and for that matter Nordost tends to be too... sorry, transparent for that kind of equipment. I have owned Simm. I prefer buying well known brands that have considered all parts of the audio spectrum and optimized for the equipment it likely to be use for. Cardas is probably the best. They are also well reviewed and respected. So, if you become familiar with their products they are easy to choose and swap out over time.... as opposed to boutique companies. This stuff it too esoteric to make it harder by adding more variables.
FYI, I use all Transparent... and currently have no Cardas in my system. But earlier when I had lessor equipment Cardas was a mainstay providing great musical experience and detail. Companies like Nordost and Transparent strive for the most transparent and neutral sound at all levels. But that can easily sound lean, overly detailed and dry in mid or lower tier audio gear.
