Why use Tungsten Carbide (TC) balls instead of [hardened] chrome steel balls?
Although the difference is difficult, if not impossible, to physically measure with instrumentation, the experts [with those precious “tuned ears”] say that Tri-Orbs sound much better in overall listening tests (i.e. tighter base, enhanced mid-range clarity, crisper highs, more dynamic soundstaging, etc., etc.). The two metals themselves are very different in composition. TC is a very heavy metal, about twice the physical weight of steel, revealing a density of 15.7g/cc compared to standard tool steel which has a density of only 7.7g/cc. To provide further evidence using the MOHS hardness standard, TC has a MOHS rating of 9+. The only substance harder is diamond with the highest MOHS rating of 10. As we all know, there is no harder substance on Earth than diamond, period! This is a fact. The higher the density and weight, the better the isolation and damping (up to a point of course). So with this in mind, TC balls must improve the performance of Tri-Orbs, maybe not by a factor of 2 (a
