Digital BW, The Print

I have to lean toward the concept of using a large format 4x5 neg
scanned on a drum scanner as apposed to using some flatbed or Imacon
scan compressed for online download, if that is what the LOC has
available. From what I've seen of dslr files, they really suffer in
the extremes and comparitavily have quite a bit of noise in those
really subtle areas. Isn't  what one really wants to show in a
comparison the best possible output from the best possibe file?
