I would think that the surface noise should be no greater than tape hiss. If that means anything to you.IMO, that's a very good analogy for someone familiar only with CDs. Plenty of CDs have tape hiss in the quiet sections.

It's interesting that LPs would not also have the tape hiss audible, since they are manufactured from magnetic tapes that often have tape hiss (unless the LPs are rare direct to disk recordings). This doesn't make sense to me.

...with some LPs, even in silent passages, there is just no surface noise and I swear that my ears are still good. Of course this is not true of all Lps, but there seems to be vinyl which is practically without noise, if everything else is done right.
