Dear edgewear, From wrong assertio or premise one can not get
triue conclusions. Your premise is that whole series Bleu is 40 Ohms
while all are 5,2 ohms . For those Kondo san designed 2 SUT's ,
One of them is made from SILVER .Probable from 100 year old
ITALIAN SILVER. This may be the reason for Alessandro's
admiration. BTW for this one one should be looking . Than those
40 Ohm in between and your Lazuli as well my Black heart are again
5,2 Ohm . The nr 3 SUT is made for both 5.2 as well 40 Ohm but
one need to switch between them with ALL intermediary wire, Not
what one would call ''pure ' or conssequent solution . .
