If this really does come out at less than $500, it will for sure replace my DX50. I think I tend to like the slightly more bright/analytical chips like Sabre or Sony's S-Master over the Wolfson. With dual mono DAC's, for close to $1000 less than the AK120, this could be huge for Ibasso.
And dual Sabre dacs. iRiver just charges way too much. I have to relax a little. I am really looking forward to this. Same size as the DX50 and such power in both a dac and while not as much as the DX100 in output, still plenty for most all applications. Fun, fun.
