In old woods the resins have oxidized to the insides of the cell walls, allowing for more vacuous cavities which, along with the diaphragmatic aspect of the board, color the tone. It also helps the vibrations travel from point to point in the board better, as old wood is therefore denser and stiffer ( i.e. transmits vibrations better than newer, softer, vibration absorbing wood. ) That said, a new board with nice crown , well made, certainly is impressive: but will develop compression set ( which the old board has, already and probably as much as it ever will ) and so the old board's only real disadvantage ( besiders the fact that it was made with hide glue, which is more susceptible to breakdown from humidity swings than modern glues ) is that it has lost crown. I'm seeking a method which remedies this, and D.L. Bullock claims to have found it, and successfully used it, for years. I'm not at all interested in fighting over this. Yes, "better" is subjective.
