We speak from experience.That's funny ..so do I. But I never get obsessed with any one company. And I do not get too carried away with any one designer as there is a wealth of talented audio engineers out there constantly improving the reproduction of music in the home.
The problem with running with cables from one company, or electronics all from one company, is that you get an additive result of colorations and flaws within that product line. If this works for you, that's fine. Even with products of tonal coherency, there is always a tradeoff between detail/clarity and the portrayal of space. Not one product yet gets it all perfect. So until then, we are each left to find a set of products, which integrate into a system to give us a hint of the qualities within the music.
