Record wear article

I haven't put a lot of thought into this, but...usually when stuff wears down tracking something not perfectly linear (grooves are wavy), they tend to get "rounded" edges. So I don't understand how a worn stylus actually wears a record more.
Most of the grooves on all types of music have only a small amount of high frequency information, so they look mostly pretty straight relative to the tiny stylus, and wear the stylus contacts pretty much flat. On a Conical stylus this doesn't change much. On an elliptical, the front and rear edges are intentionally closer together, so they get a bit sharper. On an ML the front and rear edges are much closer together, and the flat contacts form a sharp edge with the ridge cuts. Some people say this can cause groove damage, and indeed of the 4 MLs I have evaluated, the worn one caused the most severe damage.
 
Yes, this is the conventional wisdom, but do you have any data to show this to be true? I'm doing the studies because no data exists to show either way. Unfortunately I think I got a few bad VM95ML, or possibly all VM95ML have suspension issues, and the results are making MLs look bad. Conversely, the controlled nature of the experiments seem to be making the Conicals last longer than expected, so it all appears upside-down. I am really hoping the VM740xML has great tracking and lasts 2000 hours, but we'll have to wait and see.


What opposite thing did I say? I do reserve the right to learn and improve versus time, and that may make me change a viewpoint, but I rarely flip completely opposite on something. Please point out my 180.

For sure I have no agenda, other than to get to the truth. I am not making any money on these studies, and in fact have refused monetary assistance when it has been offered. I'll admit to gladly accepting donations of new Telarc Pictures records for testing, but I make sure no strings are attached. I've spent thousands of dollars and hundreds of hours on these studies, and have learned a lot along the way, so if I say something today that is a bit different from a while back or a year back, go with what I say today.

You are the very last person who should be lecturing about an agenda, and any criticism from you regarding ML's must absolutely be taken with a grain of salt due to your strong conflict of interest in these matters.
Ray I fit conical, Ogura and Shibata also but I like very micro micro ridge.
I really do think you are enjoying the attention and it feels like you want show people thry are wrong which is a concern re an agenda.
I am seeing micro ridge still good at 800 hours, and still good at even 1000 but I would never recommend taking them further.
You said on VE that the Sas was not causing wear like the ml was, now you come hear and say different.
Also you were testing on worn grooves which makes no sense at all. When a groove is gouged the next play the stylus moves more and more damage occurs.
You dont seem to want to except there are other variables in this. Seeing any profile do damage can mean arm, tracking force, bearings, compliance, basically anything could have caused it to happen.
Do we all stop using 3um or less micro ridge, micro line, sas, VDH, Paratrace, Ogura etc because some not peer reviewed hobby test online using cheap turntables says so?
I was very interested in the study when you were doing ellipticals but your unwillingness to listen to ideas about what is causing wear or the methodology is a big concern.
Your study was supposed to eliminate fake news and show people real data on how long stylus last, but it seems to have done the opposite. Now people are cherry picking bits and this fake news is ending up on Facebook making more misinformation than there ever was.
I think the study has run its couse Ray.

Chris...I am truly hoping the study has run its course for you, Chris, and that you will no longer respond to any of these related threads, but alas I think you can't resist. Talk to you soon.
Orbray have noticed you threads and AT will follow. You are going to end up getting sued.

When you post something as fact online when it is about a company you are going to get very sued.
Even if you think it is fact see how that goes with company lawyers. Ray this is not going to end well..

Wow, just wow Chris.

AT has been following these threads all along, from the very first time they had to replace a cartridge due to loose suspension. It will be good to hear what Orbray has to say.
