Are we all forgetting that audio, esp at this level is a recipe. Yep, components and materials that measure well have the advantage. But if a so-called "worse" material sounds better in synergy w the rest of the design, you'd be stupid not to choose it. Designer bias means all. I guess if the customer doesn't like the sound, he doesn't rate the bias either.
This is not how good engineering works. You don’t soften the tires to fix bad suspension design. You design the suspension right to begin with, that is if you know what you are doing...
