Why not?

Audio Note looks like a very cool company although I am sad to say I have never heard their equipment. Just the fact that they offer a DIY line puts them in another league (for the better IMHO).

I was actually aware of PS Audio and Audioquest. I bought a couple of power cords when buying a power conditioner from them on the strong advice of the sales person but I must admit I just use them because I have them now. It seemed to be a co-marketing arrangement as much as a clear endorsement. The aggravating fact is the lack of clear statements, much less data to help sort the wheat from the chaff. It seems like this cable searching business could take a lifetime and the cable sellers are not unhappy with that situation at all, much as Nonoise suggested above! I guess I'm looking to identify those manufacturers who have the courage to step forward and say something definitive with regard to how their products are connected. So, I am grateful to those of you adding to that knowledge base.

Making cables optional is a thought, especially if they can be offered at a discount,

@soix you raise an excellent point which I forgot to mention. Certainly if one or more cable models where determined to give top results the manufacturer could negotiate bulk purchase pricing to help make an attractive package deal.

My concern is that manufacturers don't speak on this issue because they don't want to stir up a hornets nest among their industry brethren. A reasonable supposition that leaves us consumers out in the cold.

Audio companies don't want to increase prices of their units with 'better cables' that may or may not work with their systems. So, they leave it to owners to decide what they like/want.

That is the reason.

(And, yes, I asked them).

@bruce19 ,

I don't see it as the way you interpret what it is that I said. My meaning is that we all  hear differently and because of that, we're all going to favor one cable over another and that the manufacturers know this by now.

To use your metaphor of "because god made it that way" presupposes that there is no other way to see hear it which brings us back, full circle, to the manufacturer knowing what's best and their suppling of the cable. I don't see it that way.

But hey, it's a free country. 😄

All the best,
Nonoise

For the same reason GM doesn't make tires. They instead partner with Michelin and try to sell you the recommended tires through a back door. GM does cars and they leave it at that. Your are asking a question from a marketing point of view that has a marketing driven answer.
