Apparently there is a new version of the North Star M192 dac, it's just being called the MKII version I believe. Seems to be completely redesigned, uses a new receiver chip, new upsampling chip and dual pcm 1796 dacs vs the cs4396 in the original version. The MKII also has balanced outs vs only single-ended outs of the original. On paper the MKII certainly appears to have a better digital section, but the output stage isn't discrete like it is in the original. Price isn't terrible either, $1375 + shipping. It's moved to the top of my list for now.
