"Two years ago you said that an SiNi ball would potentially destroy a polished steel thrust surface."
It really depends on the applied load. SiNi WILL destroy a polished steel thrust plate given enough load or cycles.
"After more than a year of continuous use there is no more than a polish mark where the SiNi ball engages the steel. There is no shearing, no material transfer, and no damaged materials. The bearing performs with a reduced noise floor, it exhibits improved micro dynamics, clarity, and focus. Even untrained ears can hear the improvement in the sonics."
Unless you left your turntable on for the entire year you'll come nowhere near the point on the S-N curve where you're going to do damage.
BUT. When you reach that point, make sure you're using a bearing system that you don't care about. I'd actually be more worried about the bearing shaft, as that part is usually not easily replaced. A SiNi ball will destroy your polished steel (polishing really has very little effect on wear). It is a complicated system that depends highly on bearing diameter, loading, and number of cycles.
No one can get around physics.
"You were wrong two years ago Mark. Can you admit you are wrong?"
Two years is a very short time for a bearing of this type. Leave that player on continuously for 1 or 2 million cycles and take another look.
"Are you willing to actually test your opinions or do you prefer to simply attack me personally?"
Most of this stuff was worked out well before I was born. I don't think anyone is personally attacking anyone else.
"Mark, you pulled the original material because it did not apply to mirror polished thrust surface. That is the reality. That is what I clearly understand."
Polishing has a miniscule effect on hardness, although a measurable effect on wear. It may increase component lifetime by 50% or so, but once again. It is not the thrust plate that I'm necessarily concerned about. It is the bearing shaft. This may be easily, and cheaply, replaceable on the 1200, but is not on most other players.
