I'm brand new to stello and to your forum also.
I'm reading your post about the DA100 because I just ordered the DA100 yesterday...signature actually.
I initialy choosed the "normal" one when i've been proposed to get the sig one for the 200 extra bucks.
Well, even if I don't even know what I2S is and have no use of balanced outputs, as one of you said, why getting limited with features to save little money?
As you seem all to worry about differences between the normal unit and the signature, here you can find data sheet for the sig model: http://www.aprilmusic.co.kr/AM/produ...00Sig_Spec.doc
hope it helps.
I plan to use it with a macmini/usb first, then, who knows?
