I'm in the market for a device that can function as a portable DAC/amp while I'm at school and work, and which can be used as a standalone amplifier while I'm at home. The home setup will be my Xonar DX running a line out to whatever amp I end up getting. The reason for this upgrade is that the soundcard of my work PC is pretty lackluster, and I would like to have the option of getting some higher impedence headphones down the line.
For now, this is only going to be driving the headphones in my sig, but I might eventually grab some DT880 250ohm's if I spot a good opportunity.
As for the devices I'm considering, I'd like to keep it around the $150 range if I can. In that range, my primary contender seems to be the Fiio 17, since it appears to do exactly what I need it to do. I would be very willing to buy used if I get a good deal.
Are there any other such devices you would recommend over the Fiio? Thanks for all the input!
