+1 Photon. A slightly different example. Manipulating the atomic structure can be done naturally; Chrysler used to, maybe still does, sets their engine blocks out for a year to relieve stresses, before machining.cheerssteve
Yeah, it was something about the rusting acting as case hardening I think.
As to the prior comment about cryo treatment being inadvisable for springs, many in the automotive industry believe otherwise. Engine valve springs are routinely cryogenically treated in pretty much every type of high performance engine building these days; F1, NASCAR, etc. Longevity increases of several hundred percent are reported depending on the metallurgy of the springs.
OK so I got the GTX D Rhodium NCF’s.More on the downside, the treble has become "silvery" with a bit of hardness and brightness. There is more extension but the sound doesn’t seem like it has opened up yet and still sounds etched and shut in.I do hope the treble hardness and brightness goes away. How long does this take?
It does go away. it takes a long time to go away. (in relation to 5 hours.)Actually it can go away and then come back. then go away again. As others have reported.Once the Rhodium is broken in, the majority of folks say it is the best.I agree. And have actually swapped more Rhodium in, taking out gold.
