Why not?

Good question. I have pondered it off and on. But, do not know of any companies doing it. A number of speaker manufacturers use wire internally made by high end manufacturers. But I haven’t seen it go further.
 

Maybe the “best” varies so much from system to system it is difficult game? But, I will say that clearly Audio Research products have a large synergy with other brands Audio Research components… so, they could theoretically follow that paradym and make or recommend the ideal cord to achieve their “best” sound among ARC only components… with a chosen speaker. 

@roxy54 Respectfully, that is really not much of an answer. If someone thinks a company is competent enough to design a box they want surely they would be competent enough to choose a wire to connect it to anther box. Further I do feel there would be a distinct marketing opportunity for a manufacturer doing so. Are you saying they believe the stock cord they supply is as good as any other? Because that is the message they seem to be sending from my viewpoint.

Burmester is company that offers complete loop and complete list of products if you like and want their system, including speakers.

As for the power cords, when you buy Burmester product, from their ’top’ or ’reference’ line, you are getting the power cord with component as well.You may buy that cord for some other gear or for some lower level Burmester stuff as well.

Now comes the tricky part. Burmester often demonstrates their system that are wired with their cables, but often they do it with Nordost Odin or Valhhala wires.

Had them both (V.and O.first series), ic’s and power cords (never the speaker cables) with complete Burmester system (except for the speakers) and the Odin’s are the best (no surprise there) but one should be carefull (imho) with Valhalla’s, as they tend to dominate on the sound of the system, making it somewhat ’clinical’ in lack of better term.

Between Valhalla’s and Burmester wires I would probablly choose Burmester’s silver ones (for the reason above mentioned) and that way you will also save few thousands.

But, it is important to say, that if you have only one Burmester component in your system (for example now I have only their 089 ’top line’ player/dac/preamp) you may have ’better’ results with some other cable brand, depending on your system and taste.After many different ones that I have tryed, now I use Synergistic Research power cord. (Burmester cable is in the box for now) Not saying that SR. is ’the best’, but it took me months of trying all that I can get my hands on (from friendly dealer and friends) and that particular one suited me the best. Again, if I change my amp and preamp, some other may sound better, who knows. I believe only to what I hear, in my system.

As for other brands, I think that Spectral recommends Mit, and Ayre Cardas (perhaps Avalon too, when its in combination with Ayre) and I think thats some other brands might have their line of cables as well (Gryphon or Naim for example)

It's the same answer that's ended up being the general consensus for all these years it's been asked, making it much, and enough, of an answer. Manufacturers know their market will experiment with and/or have their own cables to try with it.

What the manufacturers hear with a particular cable will not be what their customers hear in the context of their systems.

All the best,
