Transparent Audio? JPS? Nordost? Kubala Sosna?

Yes, they will all work.

What exactly do you find lacking in your system that you hope to achieve with a cable swap?

Do you like the sound of the Tara Two? If so and you want more of the same sort/type/sonic that Tara makes I would be very confident buying that cable.
The answer by Brf is absolutely true they all work and you'll get avid fanatics rooting for the cable they use. The only opinion that ever really matters in these sort of questions is your opinion.
To form an opinion you might try the Cable Company. They have a lending library that will allow you to hear the cable in your system in your space etc. I encourage you to get as much first hand experience as possible. Then make an educated purchase none of those cables are inexpensive so choose wisely and buy used if you can find what you like.

Hi

I'm using JPS Aluminata IC's in my system (Hovland HP 200P , Threshold SA-4e, PS Audio PWT/PWD etc.). They are playing very well. However, on the loudspeaker side I'm using Progressive Audio Verdi; those are faster than the JPS Labs with even better resolution and dynamics!

Had Transparent Reference MM2 and Ultra MM2 before; the JPS Aluminata's were better in my system.

Hope this helps.

I have JPS Aluminata and Nordost Valhallas in my system. Bioth are first rate: Valhalla a buit faster and more transparent; JPS a bit better body and bass.

Better sounding than both IMS is Stealth Indra. These really combine the best of both, plus.
