The Sopra 2 can sound great driven by it-subjective, of course. The same setup by another set of ears will be heard differently.
You will also get responses the Sopra’s should be driven by "X" SS/tube amp, and "X" brand cable.
Buy the Sopra’s and just listen with your existing cables, then evaluate after a run in period.
Speaker/room setup is priority over cables used as a tone control.
I use Nordost Heimdall 2/Frey2 wall to speaker.
As suggested, post in the cable forum, and you’ll get more detailed responses on why it will/wont work with your choice.
Demo as many as possible, and just eat return shipping charges, if any
