I have just purchased a DT660 and 250 ohm DT880 and am looking for amp/dac that is portable, battery powered so can run off an old phone (pre smartphone), and is powerful enough to drive the 250 ohm DT880.
I'm beginning to realise I shouldn't have purchased the 250 ohm version of the DT880 as now it seems I need an expensive amp to drive it. Please tell me I'm wrong.
I would prefer the cheapest thing I can find but I really have no clue on how much quality will scale with price. I have heard the headphone is more important so it seems silly to spend as much on a dac/amp as i did on the headphones.
The 660 will be used by my partner at work and by me for recording/tracking, while the 880 i will use for editing/mixing and for music listening at home.
There is the option that my partner can use her HP envy x2 instead of her dumb phone, and so a USB powered amp could be an option, but only if it is significantly better than a battery powered option. Also, I doubt the DT660 will be driven well by just her phone or laptop because her current cheap headphones aren't and, just so you know, these cheapos are hugely loud on an iPhone.
I really appreciate any help and realise I could have done a lot more research prior to starting this thread but i figured if SQ doesn't scale too considerably with price for a amp/DAC then someone might just be able to give me a quick recommendation of something cheap. On the other hand if there is a lot of things I need to consider then responding may be more difficult.
