I record as follows:
Guitar → Kemper (Studio Profile - Amp & Cab) → Focusrite 6i6 (via SPDIF) → DAW (Pro Tools on Windows 10)
I have the SPDIF output set to Master Stereo @ 0 dB and use the volume within the Amp block to ensure the signal hitting my DAW input is at -8 dB (peak). I use a metering plug-in to check it's at -8dB.
I have Pure Cab on between 1.0 and 3.5.
I then use various plugins when mixing and mastering to produce the final track.
It's just a hobby (as you'd probably see if you clicked on the link to my YouTube channel below), but that's how I set things up.
