Finally started doing this using an Apogee Duet 2. Unit will do up to 24/192, but I am doing 24/96 since the mac has some limitations past that for some things I am doing. Using Audacity like you are, but I am leaving the files full of the LP noise, as it's minimal, and most of my albums I've had for 30+ years and the noise is sort of like an old friend at this point.

Duet does a really nice job, and is also an improvement over the DAC of my 990 during playback of all my files.
