Sorry i can't remember if there was one "exact" spot where I got the info or how I found out about it or exactly. We all have different ways of trying to find things out. As to when I was looking it was after the USBPre-2 was released which means it was after 11/8/2010, so I'm not sure what info you are looking for. I get you're frustrated about the unit, but as for me, when I end up with gear that does not perform the way I want it to I either sell it or adjust my expectations. Of course YMMV. I love the uSBpre-2, maybe you could sell the mico and get one of those. OR there are V3's showing up fairly cheap too. Both of which are great sounding preamps and maybe an option to your lack of digital input. I hoped to help by posting the things I know about MICO VS 680, if those things are not helping you out, sorry, I aint got any other info or answers.
