recommended speaker cables and interconnects

I would go with Blue Jeans Cables...high quality and they make them up to order. Reasonably priced.

Before I moved to Kii Three Active speakers I was really happy with my The Chord signature reference. Used them on my Tannoy 15” K3808 Professional Syncsource  model M1000. 

I would start with a inexpensive quality cable from a respectable manufacture to use as your base line.

A great candidate would be the 12ga Mogami 3103

You never know - you might decide your money is better spent on something else

I use all Kimber Kable Base in my system with the WBT connectors for the interconnects and phono cable. (sounds better than the balanced in my opinion. (I have them in both and use all the SE cables now). They are fine and don't break the bank. 

"jpmanomet" is right on target with Mogami.  For interconnect cable I recommend the W2549 matched with the Neutrik NF2CB RCA's.  The Mogami W2549 is a microphone cable with 2 jacketed conductors made of ofc.

The soldering required for the neutrik nf2cb rca's is not easy as you have to solder the braided ground before the 2 conductors to the center cup.  You could opt for the Rean  Neutrik NYS352G Gold RCA's that use a satisfying/satisfactory crimp for the ground.

Once broken in, these cables are stunning and deliver the goods!
