I'm having trouble figuring out which of the two is better for me to create a vinyl recording at the highest volume without clipping.

I capture a record via my preamp into Audacity, and I get what seem to be relatively low levels even though I make sure the levels are right when I record (Peak: -6.4db, RMS -24.6db). Am I doing something wrong? Or are those levels right? These recordings don't seem as loud as mastered CDs.

Anyway, to get the most accurate sound possible, should I use normalize or just increase the volume? If normalizing makes everything sound the same at a peak level, doesn't that completely screw with the dynamic range of the music?

Thanks!

The gain is normally set to leave plenty of headroom when doing live recordings. Setting to reach about -20dB on expected peaks is common. This leaves that 20db to capture the unexpectedly higher peaks without clipping. If you knew for certain what the highest peak would be, you would not need to leave any headroom.

The easiest, most convenient, and most reasonable thing is to record into a floating point format. You will thus capture the maximum resolution of which the soundcard is capable, and with the lowest quantization error, and not have to fiddle with or worry about it thereafter. Stay in floating point until everything is done. As a last step, or next to the last if you intend to pull the recording apart into separate tracks, convert to integer. Here, 16 bit (preferably with dithering and good noise shaping) is perfectly adequate.
