Been playing around with 518 gain control and wanted to inquire with HH community if there is a rule of thumb regarding the best way to set the gain/volume relationship on 518/568.2, respectively?

For example, is it better to have 518 set to 0dB gain and 568.2 set to -25dB volume or better to have 518 set to -20dB gain and 568.2 set to -5dB volume?

Think I read somewhere that it is ideal to have 568.2 running close to 0dB volume to maximize DAC/processing? Or is this a moot point in that there is no actual difference between these two gain/volume relationships (e.g., 518 low and 568.2 high or 518 high and 568.2 low)?

Thanks heaps!
