Am I totally nuts or just a bit off?

A few weeks ago I came across about a hundred old mono pop jazz albums from the fifties in storage I had forgotten about.
Had some extended(3am extended) listening sessions using a Shure M78 S(sperical) tracking a little over 2 gms on my trusty Sony PS-X7 .

Sure seemed to me that mono was way cool especially in the LOW listening fatigue factor. Going on a Goodwill road trip next week-LOL,

Tell me again, why was stereo invented?

VIRIDIAN, I take your point on the M78 stylus , thanks.

Going thru my stash I found a NOS N70B shure stylus with an .0006 radius vs a .0025 for the M78, would this meet your criteria?
Truth be told I don't even know what a um is,all I ever studied was history.

Good mono recordings are also very useful as a reference standard to help get things set up well for stereo. If you get a solid and full nicely centered and focused image with good mono recordings, chances are the speaker setup will be pretty well optimized for stereo at that point as well. Its much harder to use stereo recordings as a reference in that there is so much variability in how the stereo channels are utilized from recording to recording.

:-)

"um" = "micro-meter" aka "micron" = 1 millionth of a meter = 1 millionth of about 39.37 inches.

"mil" = thousandth of an inch.

15 um = 0.00059 inches = about 0.0006 inches = 0.6 mils, as Viridian indicated.

Viridian- I played 3 records that have been in heavy rotation(oh, that Dakota Satanton)the sound is much fuller and with more detail, must be getting all of that groove!
I did't notice any damage, just less surface noise.

That whole 91ED family must be the greatest buy of all-time in audio.First real table I ever bought was an AR XA that came with one. 45 TT's and twice as many carts later I should have just stopped there, have just as good sound and I'd be 30K richer .

Al, thanks for the class, even at age 78 I got a lot to learn LOL.
