Testing the new Bruce Diamond Edison Disc Stylus.

That photo looks great to me, Larry. You can see that these are much nicer looking than the "others" just from this photo!

I'm really looking forward to getting some of these even more now!

I wonder if Tim Fabrizio knows about the new Bruce Diamond Edison styli?When he gets my work done one of the things I'll have him do is put a new styus in my C-250 DD reproducer.edisonplayer

Edisonplayer-they are not available to the public yet.

This is all good news indeed.

Larry, thank you for posting this!

Please keep us informed as to how the
long-term testing is progressing.

Only by playing hundreds, then thousands
of Diamond Disc Recreations, will the true
results be known.

Add to that, that several samples of these
new diamonds will need to undergo this
identical rigorous long-term testing before
we can really "sign off" on them as being
properly made.

It's the only way. Only by putting them
through their actual hard-usage paces, will
we ever know how they stand up in real, live,
actual service conditions.

And so it is with any new hardware which
is subjected to extreme amounts of wear,
abrasion, and excessive pressure.

Play a couple of thousand records then
have a look at it, and see what it's doing
to a pristine runoff area.

Good work!

Magnified, the picture makes it look as if the point has edges instead of being a smooth cone. I hope that's just an illusion, caused by shadow

There are no "edges" to the point when I turn it and look though a magnifying glass. It probably was the way the light fell on it near a window when I tried to get a close up.

As to the long term aspects of the diamond point, that is probably an open question. The only way anyone will know is though many plays as you point out. The other point however is that the company that is making them is quite through and is following the exact edison specs for the stylus. In the past two years I do know that some flaws were found and corrected as far as polishing was concerned. The diamond I have is the end result of their efforts to perfect the stylus and be reliable. I tend to play 10 to 20 records a day and when testing even more. It doesn't take long for me to have played a hundred records though so if its going to become a problem I will probably see it..

Failure of the stylus can be quickly brought on by playing damaged records of which there seem to be quite a number out there. Even when scanning a record visually sometimes a chip in the surface can be hiding and not show up till you hear it. By that time its possible that if the stylus is put under enough stress it could chip. I used to think like some I have read that a diamond being the hardest material would not be easily damaged, but that isn't the case and I hardily suggest anyone purchasing or playing any good stylus carefully check your lead in and playing surface for anything that might damage a other wise good stylus.

I hope this new stylus is successful and makes it into production. I believe there is a lot of pent-up demand given the issues with the ones currently being sold.

[FloridaClay]

I certainly hope that the new styli stand the test of time. However, from what I have read from posts from various people who have tried "the ones currently being sold," those fail rather quickly, or are defective from the beginning, so one need hardly wait for the new version to be used thousands of times over years before being able to discern whether or not they are better.

I have never been a fan of seeing the lid up when the records are in play due to the distortions that generally come from the diaphragm or reproducers, or so I thought. But as I have played though many records now I am finding that with the lid up I get very little of that feedback effect. Maybe someone will have a different view but I am only guessing that since the stylus is now reading the grooves well it is transmitting a clean sound it isn't producing that odd feedback to the reproducer? I know that its clearer because I always would shut the lid so as to not hear that feedback sound. Now there is very little of it. Only places I have heard it was on a record that simply was too worn to play totally clearly which would seem to go along with that theory?
