Any time you boost levels the headroom is reduced, whether it be in the analog or digital domain.

If any digital audio program material is too high, 1) reduce the global level before boosting, 2) cut instead of boosting, or 3) use floating point processing and adjust the levels when it goes to fixed point.

I'm not convinced that analog eq is always desirable with disk transfers; I know the arguments pro and con. It is very helpful to have a high quality phono preamp with a variety of curves for quick reference in auditioning a disk.
