Upgrading My Vinyl Set Up

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!

Never the source? I'm pretty convinced that GIGO applies to hi-fi as much as computers.

The source is in the components. It depends where you are. If you are doing a complete system upgrade then after the speakers you could argue the source… but I would do preamp, amp, then sources. Getting the character of your system… the speakers, preamp and amp are the heart… shared by all inputs. So you would want this perfected and stabilized before swapping inputs… TT / phono stage and DAC / Streamer.
