Dear @mikelavigne : I think that my misunderstood came from what you posted:
" the tubed power supply sounds better than a solid state power supply "
Than's for your last post where appeared not one but 3 different tube power suplies with no SS one.
Btw, " projects lots of energy and life. " :
Obviously that exist different levels but those DaVa characteristics you named are shared by cantilever-less cartridge designs as the Ikeda REX9 and others.
There is no doubt that cartridge field coil design means a " different " quality level than other cartridge design principles ( motor. ) but the DaVa comes with 2 different " principles ": catilever-less and field coil. How much for one and how much of that quality for the other. Yes, at the ends only is important its overall quality level but ??....
The field coil principle can't recovery what the DaVa design cantilever-less can't pick-up from the LP grooves due that it is not ( no one cantilever-less is. ) good tracker.
Taking in count those facts could be interesting that an Audio Note I/O LOMC owner that along owns the I/O field coil could chime here on it because both cartridges are the same but the generator variable.
