Here we go with your "theoreticals" again. 50db is a very large dynamic
range above any realistic noise floor, in reality. For example, in a
concert hall with 40db of ambient noise, 50db gets you to 90db, a reasonably
loud performance level. Moreover, since it is possible to hear details like
decay and ambience well below the noise level, the actual musical impact is
substantially more.
Nobody is arguing that CD's aren't quieter than LP's, only that on a good
rig well cared-for LP's can have a noise level that is simply not obtrusive,
as so many here seem to feel it is.

Sorry, but my left ear hearing extends out to 18khz even at my age.

No, he was pointing out that it was *there* at an obtrusive level.

No, he was pointing out that it was *there* at an obtrusive level.
