Help - Cable for High End System - M7s and Block Audio Mono A


My friend is putting together a system and I offered to help him, but at this stage, the budget has grown far above the price points where I have knowledge of components and pairings - I could use some advice.  At this time, we are focused on neutral speaker cables.  These don't have to be end game but enough to get him listening for a long time and not limit the other components.  The speakers are the Magico M7 and the amps are the Block Audio Mono A 200.

Any suggestions in the $5000 to $12000 range for a pair of speaker cables.  The other limitations are that the cables should be flexible (not overly stiff) and not have large modules or boxes in the cable.  Thank you.

@soix It is a new system so no cables.  I think neutral would be best and then he can go from there in a year or two.  Thanks.  

@jjss49 - I agree.  It is all relevant to income/net worth though and good to enjoy life and spread it around.  

I think I might start here for a whole lot less than your stated budget.  As they have a 30 day return policy and good customer service he doesn't have a lot to lose in trying them.

Careful with Nordost speaker cables. Tried Tyr 2 and they did not work for me at all despite already using Tyr 2 interconnects. Thin sound, small images in the soundstage, but very precise and they were fatiguing in my system.
Besides they are super wide, super flat and not flexible at all. 
 

If the objective is to get a full set of cables from the same manufacturer I would recommend either Kimber KS series interconnects and speaker cables combined with Kimber Ascent or Palladian power cables (neutral and natural sound) or Shunyata Sigma (slightly cooler and more studio like, analytical). If you plan to mix and match, the Audience FrontRow speaker cables are excellent and are extremely flexible. They have a natural sound. Audience FrontRow interconnects are, unfortunately, not as good as the speaker cables. 
Audioquest would be worth trying as well but the higher end.
