Sonosax stuff is elegant, not unlike a Bugatti. And maybe as fragile, too. To run against Nagra and SD you have to be rugged. Folks want recorders to work every time they turn them on. <100% just does not cut it at this price range at all. Only once would a recorder have to fail on me to get me upset.
And, being in the west, French, end of Switzerland is a ways off to be
and to also have bad customer support. SD has excellent customer support in my experience and I will bet you a fat man that Nagra does, too. So just like women, pretty is not enough to go the distance. For something serious I want a recorder I can live with, day in, day out.
As usual, YMMV
Damn sure a pretty recorder, though.
