The young ones are just picking up where we left off fuckin everything up. Pollution, drugs, WWII, Iraq, Afghanistan etc..... was not the youngsters faults.... We taught them very well and also left them a mess. Can they figure it out? Hell No.... we brought them up fucked up like we are leaving a fucked up world for them.

I have five different points for the Ortofon Super OM, a spherical for 78s, a spherical for microgroove, stylus 10 and 30 elliptical, and a DJ spherical. I have a generic of the Goldring Elan, with a 78 point, a .6mil spherical, and a .2x.7 elliptical. I keep the same cart mounted, just swap the points and increase pressure a few grams.

Glad you liked the video- a pain in the sphincter to edit! But at least I got to use the “rabbit hole” joke…

I'd be curious of a repeat with the same stylus across the board, to remove that variable. Perhaps a spherical across the board? I'm wondering if the stylus to groove relationship is causing/altering dynamics...

The only difference I can imagine would be less HF definition on the 45 and LP, but since I recorded the outer edge of the LP, the linear velocity of the groove would make the difference in stylus points moot. Even the 45 may not show much difference since that also has a higher linear velocity.

I guess the real test of this was groove modulation- the shellac had lots more room on the disc face for a small playing time (compared to the other two) and the lacquer cutter made the best use of it.

My decision to use stylus 10 over D25M (1 mil spherical) was a last- minute snap. Can’t use anything else for the fat groove on the shellac…

All your 78 copies well predated equalization techniques employed on 33 and 45 samples you played...

A bunch of different cuts from the hard drive while setting up the Audio/Midi, Tascam mixer panel, and Sound preferences on my work Macbook which has an older OS on it so I can use the Tascam with it. About got it set up - it wasn't as transparent as the iMac so it's all sounding good again.

If anything, RIAA didn't boost the bass enough, so the LF would show an even greater modulation.

Audacity 1.3.7 (left) on my ancient MacBook Pro has a greater number of preset curves, version 3 (right) for Win/Mac only has RIAA:

Victor 1947:

RIAA:

Notice- these are playback curves, not the de-emphasis curves used during the disc mastering. So yes, the shellac record from 1948 should have 6db more bass, resulting in an even wider waveform. The test is flawed, I admit, but normal listening playback really isn't so horribly wrong.
