I think all cables, whether they are PC's, IC's or spkr. cables, are tone controls of some sort. Some are intentionally made that way, others have tone adjustments as artifacts of the design, so the end result is a tone adjustment of some sort.
I bring this up merely to emphasize that cables are really a personal choice & in a lot of cases, experimentation has to be done to obtain the users best choice. Personally, I went through about 75 cables in a 3 1/2 yr. period to get what I use & although there may be something that would work even better, I'm satisfied with what I have. Also, I haven't closed the door on changing anything but I'm not actively seeking change either, although I will upgrade soon with the same manufacturer.
If you like the Flavor 2 you might like the Flavor 4 more.
