Well I bit the bullet and did the lot in one go. The volume unlock went OK apart from the anticipated going off of the backlight which I still found unerving. There is a significant increase in the volume of the NW-HD3. The upgrade from Sonic Stage 2.3>3.0 was a breeze and please anticipate a database conversion. SonicStage 3.0 looks more stable, with some increased functionality particularly in the database search. Yes the NW-HD3 does have to be initialised prior to the transfer of new SonicStage database. Unerving to say the least!! And the transfer itself was a pain up the proverbial. I have a large database and do not attempt the automatic transfer unless you want to watch a computer doing nothing for a long time and probably in an endless loop. Instead transfer a few hundred tracks at a time and all will go well. I have to say I have a large powerful PC which probably made the process somewhat easier. Everything is now up and running fine and well worth the effort.
