The finer resolution and detail of a photo taken by a competent photog.with a Nikon or Leica will still show up to a fair degree compared to a photo taken with a cheap camera when both are reproduced in an unflattering medium such as a newspaper.The point I'm making is that the higher the quality of the source,the better the end product will be.20 or 24 bit converters ensure to a greater degree that the best possible sound is stored in your 16 bit recorder.Of course,20 or 24 bit storage is superior to 16 bit,but a 16 bit recording made with great converters will compare favorably to higher bit recordings made with lesser converters.Cheers!
