i say that they do -
and the problem is elsewhere
(unless you also have a poorly done d/a system)
analog "peak" always goes higher than most digital samples (would have been if that had been the original sampled analog signal)
that is just nyquist law in action
i can show examples where they can go 60dB and even higher
like i said earlier
use minimum samples eg 2x+epsilon you will have problems
but oversample 10-20x or more and the problem goes away
now if you do nonlinear processing (compress, clip, limit, yada yada) you need to low pass filter the digital before sending it to teh d/a
or else nyquist theorem will not apply
why not lower the digital level
and boost it after d/a if you want a louder signal ?
this so called problem should be fixed in the analog domain where you can control it (and see it precisely)
trying to do it in the digital domain with invalid signals
is like pushing on a rope
