My current Jorma Prime xlr's use Bybee Slipstream Golden Quantum Purifiers which are supposed to improve tone and add some sweetness. To my ears they add some warmth and improve the musical flow. My previous Prime speakers cables had the large copper Quantum purifiers, and the same effects were heard. (For reference, I previously owned a full loom of Jorma Origo cables sans Bybee's, so I was able to quantify the impact of the purifiers).
This is a new tweak however & runs active which i'm a little iffy about. It is also not inexpensive. Personally If I was going to use a cable tweak, I'd go with
Akiko Audio as they are passive, good value & work.
