"If you're expecting 850-1000 hrs from a well polished nude conical Denon
tip then how many hrs do you expect from Shibata or MicroRidge?"
My expectations, based on my experience, would be as follows:
1) 850-1000 out of a high quality nude conical.
2) 2,000-2,500 hours out of a high quality line contact or microridge.
Note the words "high quality". Not all conicals are created equal any more than all line contacts or microline styli are created equal.
But I have put those kinds of hours on a Denon 103R before retipping it, with no ill effects (and the cartridge still sounded good when retired) as well as the higher number on a couple of decent cartridges with good quality line contact and microline styli.
This assumes both:
1) playing vinyl that is both in very good condition and very clean
&
2) careful cueing practices
