I'm looking for an amp+DAC to use with Beyerdynamic DT770 PRO's. I don't care about it being portable and my budget is £60 (about $100), I would use it for a broad range of music along with videos and movies. My source is a laptop and an iPod; would the 80ohm or the 250ohm suit me best? I have looked at Fiio mainly and can't find much else, are there any other brands you would recommend?
Any advice would be great.
