Speaker cables for Proac Ref 1.5

I have a Plinius 8200 MKII integrated amp, Arcam FMJ CD23T, and Proac Reference 1.5 speakers. I need speaker cables and don't know what to buy. Suggestions from anyone with a similar system (especially the speakers).
Do you mean the "Response" 1.5s? I own both ProAc Tablette 50 Signatures and Response 1SCs and am currently using cryogenically treated Virtual Dynamics biwired Audition speakers cables with them. The Virtual Dynamics cables are very smooth and at the same time revealing, which results in a very musically dynamic experience.

Another speaker cable that worked very well in my system with the ProAcs were Analysis Plus Oval 9s. Very full and natural sounding. What should be given great weight though are your components and your musical and sonic tastes. What speaker cables are you presently using with your gear? What improvements are you looking for? I'm using a tube DAC and tube preamp so using a revealing cable with warm tubes works very well for me, but you have all solid state gear upstream, so maybe a more forgiving and relaxed set of cables might be more to your liking. But again that depends on what you like.

Have fun and good luck in your search.
