Advice on this Board

[E-Stat]

We have no way to know that because the people who are making and selling the most expensive ones haven't published any specifications or tests to prove one way or another what performace differences exist.

While I won't attempt to speak for the large number of manufacturers, I will speak for one prominent one that does provide such information. I cite this example because these are the best cables in my experience. Scroll to the bottom to find the specs.

It's not that they can't. They just won't.

I will suggest an alternative reason: They cannot afford to or at least it does not make economic sense. The market for all high end stereo equipment is relatively small and the cost of a proper DBT trial series would be considerable for small companies. What we need is a wealthy audiophile benefactor to foot the bill.
