Nice technical post, not familiar with those numbers but I'll trust your opinion. So the Nuforce it is?

Thanks for all the feedback everyone, this site is so helpful I was choosing between the iBasso D2 Boa and the Nuforce Icon Mobile, I think I'm going to order the Nuforce tomorrow! I'm excited to see how they will match my DT 770!

Thanks for the response Larry, I always learn a lot from your posts. So the only options for a DAC/amp below $200 is the Nuforce Icon Mobile and the iBasso D2 Boa? Which is recommended? I appreciate all the help, this site has got me spending $$$ like no other

I am looking for an amp/dac for under $200, so far I've narrowed it down to Nuforce Icon Mobile and the iBasso D2 Boa, does anyone have any recommendations? Will a dac/amp improve the sound that much?
