Gopher,
As I wrote in a much earlier post, compared to Def1.5, Def2 had a little less snap, in exchange for which it delivered a more relaxed presentation than the excitable MDF cabinet in the v1 speaker. First the HO drivers from 2010 and now the nano drivers even further restore the snap of v1 without reintroducing the cabinet talk and glare. One of the by products is more apparent aliveness at low volumes. With nano drivers, this is elevated further by the greater definition, agility and resolution intrinsic to the nano across its range. My move to Def4 improved low volume listening over Def2, but I can also say that upgrading to the older HO drivers in Def2 had similar benefits on Defs I heard so equipped. The nano drivers in your Def2 will help your late night listening at low SPL.
