I know that 120VA is overkill, but look at Naim Audio and their power
supplies for preamps. Why they are doing it ? Are they so stupid ?

Big transformator has lower impedance, than the small one. Good power
suplly should have the lowest possible impedance.

Thats the reason why i took one 120VA :)
