Inherent to PCM audio is that the highest frequency one can record properly should be < ½ fs (sample rate).
Vinyl can reproduce up to 25 kHz (but higher values are reported) hence 44.1 is a bit low.
96 allows for frequencies up to 48 kHz
Recording at 96 gives you sufficient headroom, you will capture all frequencies in the recording imho.
It is a job to find the loudest passage for each LP.
Recording at 24 gives you more headroom then 16.
If you have a healthy headroom of about 20 dB, with 16 bits you are recording with 16-3=13 bit resolution. Better use 24

RE: "Recording at 96 gives you sufficient headroom, you will capture all frequencies in the recording imho." per Roseval.
Thanks for that info, with which I am familiar. However, it basically tells me that 25/96 is good. It does NOT address either whether 24/192 might be better, or why NOT to use 24/192.
So, I'm still looking to hear about testing/comparison/personal experience from someone.
If you look at the signal to noise ratio dynamic range of an LP it is around 80dB or so, maybe 90dB on a good day under ideal conditions.
24/96 offers a practical dynamic range of about 120dB - 130dB which is more than sufficient with plenty of headroom for digitizing vinyl. Trying to digitize vinyl at higher resolutions is a waste IMHO because the additional resolution has nothing more to capture off the record except for perhaps more noise.... and the file sizes become unnecessarily huge.
Yes, disk space is cheap. If you can personally hear an improvement in digitizing vinyl at higher than 24/96 resolution, go for it. I can't hear any benefit between 24/96 and 24/192 on the records that I have digitized.
