Upgrading My Vinyl Set Up

You might try posting this under "cables"

PL HP user here.

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

I agree with tablejocky. IME most folks judge speaker cables on their effect on the tone/color of the sound they produce with any giver component/speaker set up. They interact with the associated equipment (all of it) so it becomes very difficult for anyone to advise you without at least having some reference point. It's all about synergy and your sonic expectations. The best cable (whatever that might be) can sound great or crappy in any given system, as a lesser cable can sound great as well (or crappy). Its easy to get descriptions of the sound potential of many cables (i.e. silver cables, Nordost cables, etc sound bright, Belden sound dullish, etc) but that really is not meaningful because in some systems either can sound very good). 

The speakers you are planning for should be a huge upgrade. 
 

Since they are from the same company, they presumably have the same sound… but they are likely to be much more resolving and dynamic. So, may sound better with different cables. 

‘In any case you must try them in your system.

I would recommend not trading cables at this point and accelerating your speaker purchase. Which might cause you to rethink some other aspect. I always recommend speakers first, component adjustment, then cables and finally vibration control. The largest impacts first… carefully adjusting the less important aspects to optimize them all.

Great idea, thank you!
